ABSTRACT

Fundamento: Los linfomas primarios de ovario son poco frecuentes; el 1 % de estos se presenta en ovario y el 1.5 % de los tumores malignos de ovario son linfomas. Los tipos histológicos más frecuentes es el linfoma no Hodgkin difuso de células B grande y el BurKitt; el tratamiento consiste en cirugía combinada con quimioterapia. Objetivo: Reportar un caso de un linfoma no Hodgkin difuso de células B grande primario de ovario. Presentación de caso: Se presentó el caso de una paciente de 39 años de edad, con antecedentes patológicos personales de salud; la cual fue al cuerpo de guardia de ginecología por presentar dolor abdominal difuso que no se aliviaba con analgésicos. En la exploración física presentaba dolor a la palpación superficial y profunda en hipocondrio y fosa ilíaca derecha con masa tumoral palpable. Ecografía hacia proyección anexial derecha se observó una imagen de baja ecogenicidad y en la laparoscopia de urgencia se concluyó como una formación de aspecto tumoral que parecía corresponderse con ovario derecho. Se le realizó una histerectomía con doble anexectomía. El diagnóstico anatomopatológico fue un linfoma no Hodgkin primario de ovario. Conclusiones: La paciente del caso presentado tuvo una clínica oligosintomática y la confirmación de la enfermedad fue a partir de una muestra quirúrgica, lo que expresa que el diagnóstico del linfoma no Hodgkin de células B es difícil y aunque es poco frecuente siempre se debe tener en cuenta en el diagnóstico diferencial de las tumoraciones unilaterales de ovario.


Background: Primary ovarian lymphomas are uncommon, 1% of these malignancies occur in the ovary, and 1.5% of all ovarian malignancies are lymphomas. The most common histologic types are diffuse large B-cell non-Hodgkin's lymphoma and BurKitt's lymphoma; treatment consists of surgery combined with chemotherapy. Objective: To report a case of primary ovarian diffuse large B-cell non-Hodgkin lymphoma. Case presentation: A 39-year-old female case is presented, with a personal pathological history; she went to the gynecology emergency service because she presented diffuse abdominal pain that was not relieved by analgesics. Physical examination revealed superficial and deep pain on palpation in the hypochondrium and right illiac fossa with a palpable tumor mass. Right adnexal ultrasound showed an image of low echogenicity and at the emergency laparoscopy, it was diagnosed as a tumor-like formation that appeared to correspond to the right ovary. She underwent a hysterectomy with double adnexectomy. The anatomopathologic diagnosis was primary ovarian non-Hodgkin's lymphoma. Conclusions: The patient in the presented case had an oligosymptomatic clinical presentation. Confirmation of the disease was obtained from a surgical sample, which means that B-cell non-Hodgkin's lymphoma is difficult to diagnose and although it is uncommon, it should always be considered in the differential diagnosis of unilateral ovarian tumors.

ABSTRACT

Adjuvant-induced autoimmune/inflammatory syndrome leads to capsular contracture and fibrosis from the oxidation that takes place in silicone. Anaplastic large cell lymphoma occurs through the development of a seroma, with the formation of a periprosthetic effusion, or through the infiltration of the condition itself. To analyze these conditions, a review of the literature was carried out on the symptoms and pathophysiology of the autoimmune/inflammatory syndrome induced by adjuvants and anaplastic large cell lymphoma, searched using the terms "ASIA breast silicone," "Lymphoma," "Adjuvants" "Immunologic" " Breast Implants" on the PubMed platform. Analyzing the data obtained, it was noted that the symptoms of the autoimmune/inflammatory syndrome induced by adjuvants are nonspecific, such as fatigue, myalgia, arthralgia, morning stiffness, and night sweats, and therefore need attention. Anaplastic large cell lymphoma presents with breast pain, periprosthetic effusion, and palpable mass, among other characteristics. Because of these aspects, it is concluded that a good investigation should be carried out when nonspecific symptoms appear, regardless of the time the surgery was performed since these complications can occur years later.


A síndrome autoimune/inflamatória induzida por adjuvantes leva à contratura capsular e fibrose pela oxidação que acontece no silicone. O linfoma anaplásico de grandes células ocorre através do desenvolvimento de um seroma, com a formação de derrame periprotético ou por uma infiltração da própria afecção. Para análise destes acometimentos, foi realizada uma revisão da literatura acerca da sintomatologia e fisiopatologia da síndrome autoimune/inflamatória induzida por adjuvantes e linfoma anaplásico de grandes células, pesquisada através dos termos "ASIA breast silicone" "Lymphoma" "Adjuvants" "Immunologic" "Breast Implants" na plataforma PubMed. Analisando os dados obtidos, notou-se que os sintomas da síndrome autoimune/inflamatória induzida por adjuvantes são inespecíficos, como fadiga, mialgia, artralgia, rigidez matinal e suores noturnos, e, portanto, necessitam de atenção. Já o linfoma anaplásico de grandes células se apresenta com dor mamária, derrame periprotético, massa palpável, dentre outras características. Em vista destes aspectos, conclui-se que uma boa investigação deve ser realizada ao surgirem sintomas inespecíficos, independentemente do tempo que a cirurgia foi realizada, uma vez que estas complicações podem ocorrer anos após a cirurgia.

ABSTRACT

Resumen ANTECEDENTES: Durante el embarazo es más común el linfoma de Hodking que el no Hodking; afecta, en promedio, a mujeres de 30 años (18-44 años) y más. Suele diagnosticarse alrededor de las 28 semanas de embarazo y está documentado que puede llegarse al término. Los esquemas de tratamiento pueden iniciarse en el posparto inmediato o, incluso, antes. La incidencia mundial del linfoma no Hodking es de 0.8 por cada 100,000 mujeres; se desconoce la supervivencia durante el embarazo. CASO CLINICO: Paciente de 34 años, con antecedentes obstétricos de tres embarazos, una cesárea y un aborto y el embarazo actual en curso de las 29 semanas, referida de la ciudad de Colima debido a un reporte de BI-RADS 3 en el ultrasonido de mama y un nódulo mamario palpable, con evidencia de múltiples tumoraciones en la zona hepática, esplénica y peripancreática. La biopsia tomada de las zonas de la lesión reportó: linfoma de células B de alto grado de malignidad, con morfología blastoide y expresión de C-MYC y BCL2. Además, la paciente se encontró con: anemia, dolor abdominal, múltiples nódulos hepáticos y adenopatías abdominales. Se decidió la interrupción del embrazo a las 30 semanas, con la obtención de un recién nacido, sin complicaciones. Enseguida se inició el tratamiento con rituximab-etopósido-prednisolona-vincristina-ciclofosfamida-doxorrubicina (R-EPOCH) con adecuada adaptación por la paciente. CONCLUSION: Puesto que la información bibliográfica de linfoma y embarazo es escasa el caso aquí reportado es relevante por su aporte. La atención multidisciplinaria favorecerá siempre el pronóstico de las pacientes.


Abstract BACKGROUND: Hodking's lymphoma is more common during pregnancy than non-Hodking's lymphoma; it affects, on average, women aged 30 years (18-44 years) and older. It is usually diagnosed around 28 weeks of pregnancy and is documented to be carried to term. Treatment regimens can be initiated in the immediate postpartum period or even earlier. The worldwide incidence of non-Hodking's lymphoma is 0.8 per 100,000 women; survival during pregnancy is unknown. CLINICAL CASE: 34-year-old patient, with obstetric history of three pregnancies, one cesarean section and one abortion and the current pregnancy in progress at 29 weeks, referred from the city of Colima due to a report of BI-RADS 3 on breast ultrasound and a palpable breast nodule, with evidence of multiple tumors in the hepatic, splenic and peripancreatic area. Biopsy taken from the lesion areas reported: high grade malignant B-cell lymphoma, with blastoid morphology and expression of C-MYC and BCL2. In addition, the patient was found to have: anemia, abdominal pain, multiple hepatic nodules and abdominal adenopathies. It was decided to terminate the pregnancy at 30 weeks, with the delivery of an uncomplicated newborn. Rituximab-Etoposide, Prednisone, Vincristine, Cyclophosphamide, and Doxorubicin (R-EPOCH) therapy was started immediately with adequate adaptation by the patient. CONCLUSION: Since bibliographic information on lymphoma and pregnancy is scarce, the case reported here is relevant for its contribution. Multidisciplinary care will always favor the prognosis of patients.

ABSTRACT

Os linfomas B primários cutâneos (LBPCs) são linfomas não Hodgkin, de acometimento exclusivamente cutâneo, e representam 25% dos linfomas primários cutâneos. São divididos, conforme comportamento clínico, em indolentes e intermediários. O tratamento das formas indolentes inclui a cirurgia, a radioterapia e, em casos extensos, o rituximabe. Relata-se o caso de mulher de 57 anos, com placa única no braço esquerdo, com diagnóstico de LBPC da zona marginal, tratado com excisão com margens de segurança de 5mm, sem recidiva após 36 meses de seguimento. A cirurgia é uma alternativa terapêutica com bom resultado clínico, sem impacto na sobrevida livre da doença.


Primary cutaneous B-cell lymphomas are non-Hodgkin lymphomas presenting only in the skin and represent 25% of all primary cutaneous lymphomas. Based on their clinical behavior, they are classified into indolent and intermediate forms. Treatment of indolent forms includes surgery, radiotherapy, and, in extensive disease, rituximab. We report a case of a 57-year-old woman with a single nodule in the left arm treated with surgical excision with 5-mm security margins, without relapse after 36 months. Surgery is a therapeutic option in these lymphomas without compromising disease-free survival.

ABSTRACT

Resumen INTRODUCCIÓN: Los linfomas no Hodgkin son un grupo heterogéneo de neoplasias hematolinfoides, de manifestación principal ganglionar; un pequeño porcentaje tiene un origen extra-ganglionar. Se han descrito algunos casos de linfomas no Hodgkin primarios de ovario y, en general, del conducto genitourinario femenino. Debido a su poca frecuencia suponen un reto diagnóstico, clínico y patológico. Se informa el caso de una paciente con linfoma no Hodgkin primario de ovario, a quien se le practicó citorreducción quirúrgica primaria y tratamiento coadyuvante con quimioterapia sistémica. Se revisa la bibliografía en torno a los criterios diagnósticos y el pronóstico de la enfermedad. CASO CLÍNICO: Paciente de 65 años, que acudió a consulta debido a un síndrome constitucional y síntomas irritativos urinarios; al ingreso tuvo signos vitales dentro de los parámetros de referencia y en el examen físico se encontraron: edema grado 2, bilateral, en los miembros inferiores y marcada palidez mucocutánea. Los estudios complementarios evidenciaron anemia microcítica hipocrómica heterogénea y trombocitosis. La resonancia magnética reportó la existencia de una masa anexial derecha, compleja, por lo que se practicó la citorreducción quirúrgica primaria. El estudio anatomopatológico reveló que se trataba de un linfoma no Hodgkin B primario de ovario. El tratamiento consistió en quimioterapia, con esquema R-CHOP. Diez meses después se estableció la curación de la enfermedad mediante estudios de imagen y pruebas de laboratorio. CONCLUSIONES: El linfoma no Hodgkin primario de ovario es una causa poco frecuente de afectación extraganglionar y se trata de un diagnóstico de exclusión, que requiere confirmación histopatológica. El pronóstico sugiere que la enfermedad confinada al ovario muestra una tasa de supervivencia global de 79% a 10 años. Se requieren estudios adicionales, que caractericen el pronóstico y el procedimiento diagnóstico de esta enfermedad.


Abstract INTRODUCTION: Non-Hodgkin's lymphomas are a heterogeneous group of neoplasms hematolymphoid, with main lymph node manifestation; a small percentage have an extra-nodal origin. Some cases of non-Hodgkin's lymphomas have been described.Primaries of the ovary and, in general, of the female genitourinary duct. Because of his they infrequently pose a diagnostic, clinical and pathological challenge. We report the case of a patient with primary ovarian non-Hodgkin's lymphoma, who underwent primary surgical cytoreduction and adjuvant treatment with systemic chemotherapy. The bibliography around the criteria is reviewed diagnosis and prognosis of the disease. CLINICAL CASE: A 65-years-old patient who presented constitutional syndrome and urinary irritative symptoms, her vital signs at the admission were normal, at the physical examination bilateral grade 2 edema in lower limbs and mucocutaneous paleness was observed, heterogeneous hypochromic microcytic anemia, thrombocytosis and also a right complex ovarian mass were documented during the hospitalization, for this reason was treated with primary surgical reduction, the histopathological result was Ovarian Primary Non Hodgkin B-cell Lymphoma, for that reason systemic adjuvant chemotherapy with R-CHOP scheme was initiated, at the ten month follow-up radiological and nuclear examinations were performed confirming the remission of the disease. CONCLUSIONS: Primary ovarian non-Hodgkin lymphoma is an unusual extra-nodular hematolymphoid neoplasm that requires a histopathological confirmation. The prognosis according to the literature review for the disease limited to the ovary has an overall survival rate of 79% to 10 years after diagnosis. More studies are required to characterize the prognosis and diagnostic approach of this entity.

ABSTRACT

ABSTRACT The report describes the clinic of an aggressive non-Hodgkin lymphoma, primary cutaneous diffuse large-B cell lymphoma, leg type (PCDLBCL-LT), and shows its relevance for addressing the case of a rare lymphoma, with complex diagnosis and, in most cases, late as there are few studies reported on the subject. Since it is an aggressive pathology, it is essential to have the dissemination of knowledge to assist in the early diagnosis of the disease and, consequently, in the choice of a more effective treatment. Therefore, we seek to demonstrate the main clinical characteristics, as well as the diagnostic approach, staging, and the symptomatic and specific treatment of PCDLBCL-LT.


RESUMEN Este trabajo describe la clínica de un linfoma no Hodgkin extranodal agresivo, el linfoma cutáneo difuso de células B grandes, tipo pierna (LCDCGTP), y muestra su relevancia en abordar el caso de un linfoma raro, de diagnóstico complejo y, en la mayor parte de las veces, tardío ante la carencia de estudios sobre el asunto. Por ser una enfermedad agresiva, debe existir una mayor difusión de conocimiento para ayudar a su diagnóstico precoz y, consecuentemente, la selección de un tratamiento más eficaz. Por lo tanto, buscamos demostrar las principales características clínicas, así como el abordaje diagnóstico, la estadificación y el tratamiento sintomático y específico del LCDCGTP.


RESUMO Este trabalho descreve a clínica de um agressivo linfoma não Hodgkin extranodal, o linfoma cutâneo difuso de grandes células B, tipo perna (LCDCBTP) e mostra sua relevância ao abordar o caso de um linfoma raro, com diagnóstico complexo e, na maioria das vezes, tardio devido aos raros estudos sobre o assunto. Por ser uma patologia agressiva, é primordial haver maior difusão de conhecimento para auxiliar no diagnóstico precoce da doença e, consequentemente, na escolha de um tratamento mais eficaz. Portanto, buscamos demonstrar as principais características clínicas, bem como a abordagem diagnóstica, o estadiamento e o tratamento sintomático e específico do LCDCBTP.

ABSTRACT

RESUMEN Fundamento: el linfoma testicular constituye entre el 1 y el 9 % de los tumores testiculares, es el tumor testicular maligno más frecuente en los varones mayores de 50 años. El pronóstico es reservado debido a una gran tendencia a la propagación sistémica temprana. La presentación clínica más habitual, dolor testicular a la palpación y espontáneo, con aumento del volumen y de la consistencia testicular. Su tratamiento se sustenta en tres pilares fundamentales: orquiectomía, quimioterapia y radioterapia. Objetivo: describir un enfermo con linfoma testicular tipo B de célula grande. Presentación del caso: paciente masculino de 55 años de edad, hipertenso, fumador 10 cigarrillos al día, bebedor ocasional. Acude a consulta por aumento de volumen testicular izquierdo. En la analítica se observa elevación del lactato deshidrogenasa. Ecografía: teste izquierdo con ecogenicidad muy heterogénea, parénquima desestructurado, sin lesiones nodulares. Engrosamiento difuso del epidídimo. Vascularización incrementada. Se realiza orquiectomía radical inguinal, al ser el diagnóstico anatomopatológico linfoma difuso de células grandes tipo B, en la actualidad ha sido tratado con quimioterapia, por presentar además afectación ósea. Pero ha evolucionado favorablemente. Conclusiones: el linfoma testicular es una enfermedad poco frecuente, a pesar de ser considerado el tumor testicular más común en mayores de 60 años. En su mayoría se trata de linfomas no Hodgkin difusos de grado intermedio alto de malignidad e inmunofenotipo B. El pronóstico siempre es reservado debido a su gran tendencia a la propagación sistémica. El tratamiento está basado en la cirugía (orquiectomía radical inguinal), quimioterapia y radioterapia.


ABSTRACT Background: testicular lymphoma constitutes between 1 and 9 % of testicular tumors; it is the most frequent malignant testicular tumor in men over 50 years of age. The prognosis is reserved due to a great tendency to early systemic spread. The most common clinical presentation is testicular pain on palpation and spontaneous, with increased volume and testicular consistency. Its treatment is based on three fundamental pillars: orchiectomy, chemotherapy and radiotherapy. Objective: to describe a patient with large cell type B testicular lymphoma. Case report: 55-year-old male patient, hypertensive, smoker 10 cigarettes a day, occasional drinker. He goes to consultation due to left testicular volume increase. In the laboratory tests, the lactate dehydrogenase is elevated. Ultrasound Scand: Left testicle with very heterogeneous echogenicity, unstructured parenchyma, no nodular lesions. Diffuse thickening of the epididymis. Increased vascularization. Inguinal radical orchiectomy is performed, the anatomic-pathological diagnosis being diffuse large B cell type lymphoma, it has now been treated with chemotherapy, because he alsopresented bone involvement. But he has evolved favorably. Conclusions: testicular lymphoma is a very rare entity, despite being considered the most common testicular tumor in people over 60 years of age. The majority are diffuse non-Hodgkin lymphomas of high intermediate degree of malignancy and immune-phenotype B. The prognosis is always reserved due to its great tendency to systemic spread. The treatment is based on surgery (radical inguinal orchiectomy), chemotherapy and radiotherapy.

ABSTRACT

RESUMEN: El absceso esplénico es una patología poco frecuente; su incidencia es baja (0,2 a 0,7%)1,2; por tanto, es importante individualizar el tratamiento, buscar su causa y ofrecer al paciente el mejor manejo. Hasta hace algunos años, un absceso esplénico se lo trataba siempre mediante esplenectomía; sin embargo, actualmente, debido a la importante función inmunitaria del bazo, su extirpación quirúrgica es la última alternativa. Inicialmente, se debe intentar tratamiento médico con antibióticos de amplio espectro; luego probablemente se requiera pensar en el drenaje guiado por tomografía y, finalmente, la tercera opción es la esplenectomía. En este artículo presentamos el caso de un paciente con un absceso esplénico grande (aproximadamente 550 ml) del polo superior, secundario a un linfoma esplénico abscedado que fistulizó hacia el fondo gástrico. A propósito de este paciente, revisamos la literatura médica y realizamos algunas recomendaciones para el manejo de esta patología.


ABSTRACT: Splenic abscess is a rare condition with a low incidence (0,2 to 0,7%). It is important to individualize treatment, seek its source and offer the patient the best management. Until a few years ago a splenic abscess was always treated with splenectomy. Nowadays, due to the important immune function of the spleen surgical removal is the last alternative. Initially medical treatment with broad spectrum antibiotics should be attempted. The next step is usually tomography-guided drainage. The last step used if other methods fail is splenectomy. In this article we present a case of a patient with a large splenic abscess (550 ml approximately) from the upper pole secondary to B cell lymphoma that fistulized towards the gastric fundus. We reviewed the current medical literature regarding this pathology and the current treatment algorithm.Keywords: splenic abscess, B cell lymphoma, gastrosplenic fistula.

ABSTRACT

ABSTRACT Background Prognosis of patients with Diffuse Large B Cell Lymphoma (DLBCL) is highly variable, and despite the use of modern immunochemotherapy regimens, almost 50% of patients will eventually relapse. Standard risk models, like the International Prognostic Index or the Revised International Prognostic Index (R_IPI) incorporate patient and tumor characteristics but do not consider variables related to host adaptive immunity which have been shown to be of significant prognostic value in non-Hodgkin lymphomas. Aim To analyze the prognostic significance of the absolute monocyte count at diagnosis in diffuse large-B-cell lymphoma in a retrospective setting. Material and Methods We reviewed data of 171 patients with DLBCL treated with Rituximab-based immunochemotherapy at two reference public Hospitals in Montevideo-Uruguay. The outcome measures were overall and relapse free survival. Results The absolute monocyte count, analyzed as a dichotomized variable predicted progression-free and overall survival in low risk patients according to the R-IPI score. Worse outcomes were observed in those with high monocyte count al diagnosis. Conclusions Absolute monocyte count could help in the identification of high-risk patients otherwise expected to have a good prognosis according to traditional scores.


Antecedentes El pronóstico de pacientes con Linfoma Difuso de Células B Grandes (DLBCL) es muy variable y el 50% de los pacientes recae a pesar de uso de regímenes actualizados de inmuno-quimioterapia. Los modelos pronósticos clásicos como el International Prognostic Index o el Revised International Prognostic Index (R_IPI) incorporan características del paciente o del tumor pero no incorporan variables asociadas a la inmunidad adaptativa que tienen valor en linfomas no Hodgkin. Objetivo Analizar retrospectivamente el valor pronóstico del recuento absoluto de monocitos al momento del diagnóstico en pacientes con DLBCL. Material y Métodos Se revisó información de 171 pacientes con DLBCL tratados con inmuno-quimioterapia basada en rituximab en dos centros de referencia públicos de Montevideo, Uruguay. Las variables de resultado fueron la sobrevida global y libre de recaída. Resultados El recuento absoluto de monocitos, tratado como una variable dicotómica, predijo la sobrevida libre de recaída en pacientes de bajo riesgo, de acuerdo al puntaje R-IPI. El pronóstico fue peor en pacientes con altos recuentos al momento del diagnóstico. Conclusiones El recuento absoluto de monocitos puede identificar pacientes de alto riesgo, clasificados como de bajo riesgo por los puntajes tradicionales.

ABSTRACT

RESUMEN El linfoma difuso de células B es el tipo más común de linfoma no Hodgkin en adultos y se caracteriza por su agresividad y amplia localización. La primera señal de su presencia es una masa de nódulos linfáticos que crece rápidamente. Se presenta el caso de una paciente de 64 años de edad, con antecedentes patológicos de hipertensión arterial, exfumadora, que fue ingresada porque desde hacía 3 meses presentaba aumento de volumen de la región lateral izquierda del cuello. Los estudios clínicos, de imágenes, de citología por aspiración, medulograma y biopsia medular y biopsia de ganglio permitieron realizar el diagnóstico y estadiamiento para comenzar tratamiento con ciclofosfamida, doxorrubicina, vincristina y prednisona más el anticuerpo monoclonal rituximab según protocolo para estos tumores. A dos meses de tratamiento se había logrado la reducción de las masas ganglionares. Se presenta el caso porque es de interés para especialistas y personal en formación.


ABSTRACT Diffuse B-cell lymphoma is the most common type of non-Hodgkin lymphoma in adults characterized by its aggressiveness and wide location. The first sign of its presence is a rapidly growing mass of lymph nodes. The case of a 64-year-old patient is presented, with a pathological history of arterial hypertension, ex-smoker, who was admitted because for 3 months she had increased volume of the left lateral region of the neck. Clinical studies, imaging, aspiration cytology, medullogram and spinal biopsy and lymph node biopsy allowed diagnosis and staging to begin treatment with cyclophosphamide, doxorubicin, vincristine and prednisone plus the monoclonal antibody rituximab according to the protocol for these tumors. Two months after treatment, the reduction of ganglionic masses had been achieved. The case is presented because it is of interest to specialists and training personnel.

ABSTRACT

RESUMEN Se presenta el caso de un paciente masculino de 21 años, quien el 30 de diciembre de 2017 comenzó con aumento de volumen, rubor y calor en región lateral derecha del cuello, posterior a la presencia de un forúnculo en región occipital del cuero cabelludo. Se inició tratamiento con antibiótico, pero aparecieron lesiones eritematopapulosas en tronco y extremidades que se interpretaron como una reacción adversa al medicamento. Comenzó con fiebre mantenida de 380C, decaimiento marcado, pérdida de peso, hepatomegalia y adenopatías pequeñas y no dolorosas en regiones inguinales y axilares, por lo que fue ingresado el 14 de enero de 2018 en el Hospital Gustavo Aldereguía Lima, de Cienfuegos y se impuso tratamiento con antibiótico ante un perfil hematológico que indicaba sepsis asociada. Se realizó aspiración con aguja fina que resultó negativa y se hicieron coordinaciones para biopsia. El 15 de enero empeoró el estado clínico del paciente con fiebre elevada, desorientación, marcada excitación, toma de conciencia e insuficiencia respiratoria, por lo que falleció el día 16. La autopsia reveló como causa básica de muerte la granulomatosis linfomatoide. Por ser esta una entidad infrecuente, desconocida por gran cantidad de clínicos y cuyo tratamiento y pronóstico no está definido, se decidió la presentación del caso.


ABSTRACT The case of a 21-year-old male patient is presented, who on December 30, 2017 began with increased volume, flushing and heat in the right lateral region of the neck, after the presence of a boil in the occipital region of the scalp. Treatment with antibiotic was started, but erythe-matopapular lesions appeared on the trunk and extremities that were interpreted as a medication adverse reaction. He started with a maintained fever of 38 0C, malaise, weight loss, hepatomegaly and small non-painful adenopathies in the inguinal and axillary regions, so he was admitted on January 14, 2018 at the Gustavo Aldereguía Lima Hospital in Cienfuegos and was treated with antibiotic before a hematological profile which indicated associated sepsis. A fine-needle aspiration was performed, which was negative and arrangement for biopsy was made. On January 15, the clinical condition of the patient worsened with high fever, disorientation, marked excitement, awareness and respiratory insufficiency, and he died on the 16th. Autopsy revealed lymphomatoid granulomatosis as the main cause of death.

ABSTRACT

Abstract Background: Diffuse large B-cell lymphoma (DLBCL) makes up from 25% to 40% of all non-Hodgkin lymphomas (NHL) and is the most common histological subtype worldwide. In Ecuador, DLBCL makes up 49% of all NHL cases, but there have been no studies on the immunophenotypic classificationof DLBCL in germinal center (GC) and non-germinal center (NGC)subtypes.This study was conducted to ascertain the immunophenotypic profile of DLBCL in an Ecuadorian hospital. Methods: A total of 38 DLBCL cases from 2006 to 2015 were compiled from the Pathology Service at Metropolitan Hospital (HM) in Quito, Ecuador. Eleven of these cases failed to meet the inclusion criteria; thus, the final sample consisted of 27 cases. Manual tissue microarrays were constructed, and three immunohistochemical markers (CD10, BCL6, and MUM1) were applied according to the Hans algorithm; in addition, the expression of the c-myc protein expression was also investigated. Results: The results showed that 77.8% of cases were of the GC subtype, 11.1% were NGC, and 11.1% were unclassifiable according to the Hans algorithm. Conclusions: The most frequent DLBCL subtype was GC, with 21 cases; and 40.7% of these cases overexpressed c-myc.


Resumen Antecedentes: El linfoma difuso de células grandes B (LDCGB) constituye el 25 al 40% del total de los linfomas no Hodgkin (LNH) y es el subtipo histológico más frecuente en el mundo. En Ecuador el LDCGB corresponde al 49% del total de los casos de LNH, sin embargo no hay estudios de clasificación inmunofenotípica del LDCGB en centro germinal (CG) y no centro germinal (NCG). Este estudio se realizó para conocer el perfil inmunofenotípico del LDCGB en un hospital de Ecuador. Métodos: Se recopiló del Servicio de Patología del Hospital Metropolitano de Quito, Ecuador, un total de 38 casos de LDCGB desde el 2006 al 2015, de los cuales 11 no cumplieron con los criterios de inclusión. La muestra final fue de 27 casos. Se realizaron microarreglos tisulares manuales para la aplicación de tres marcadores de inmunohistoquímica según el algoritmo de Hans (CD10, BCL6 y MUM1) y luego se correlacionó con la sobreexpresión de la proteína c-MYC. Resultados: El 77,8% de casos fue tipo CG, 11,1% fue NCG y 11,1% fueron inclasificables según Hans. Conclusiones: El subtipo de LDCGB más frecuente fue CG con 21 casos y de estos 40,7% sobreexpresaron c-MYC.

ABSTRACT

Objetivo: Evaluar el valor pronostico del índice linfocito monocito (ILM) en la sobrevida global de los pacientes con Linfoma de células grandes B difuso (LCGBD) del Hospital Edgardo Rebagliati Martins. Métodos: Estudio longitudinal retrospectivo. Se incluyó a los casos de LCGBD diagnosticados en el Hospital Nacional Edgardo Rebagliati Martins durante el período 2010-2017. No se realizó muestreo, se trabajó con la totalidad de la población que cumplió con los criterios de selección por ser esta pequeña y accesible. Se revisó las historias clínicas de los pacientes obteniéndose información del tiempo en meses de supervivencia, del ILM así como de variables sociodemográficas, clínicas y de laboratorio. Resultados: Se incluyó en el análisis a 121 pacientes con LCGBD; de ellos, el 57% eran de sexo femenino y 66.1% eran mayores de 60 años. De acuerdo al Status Zubrod, el 66,5% correspondieron al grado de mejor pronóstico y el 59.5% presento sintomas B asociados. Cerca del 60% fueron diagnosticados en estadios I y II y el 57% presento compromiso extraganglionar. El análisis bivariado con el modelo de riesgos proporcionales de Cox mostró que el ILM<2 constituyó un predictor de la supervivencia global del LCGBD (p=0,011) estimándose un HR=2.2 (IC 95%: 1.2-4.1); asimismo, un ILM< 1,7 también constituyó predictor (p=0,009) estimándose un HR=2.2 (IC 95%: 1.2-4.1). El ILM<2,7 no constituyó predictor de la supervivencia global. Conclusión: El ILM podría utilizarse como un índice pronóstico debido a que constituye un predictor de la supervivencia global de los pacientes con LCGBD del Hospital Nacional Edgardo Rebagliati Martins.


Objetive: To evaluate the prognostic value of the monocyte lymphocyte index (ILM) in the overall survival of patients with diffuse large B-cell lymphoma (LCGBD) of the Edgardo Rebagliati Martins Hospital. Methods: Retrospective longitudinal study. We included cases of LCGBD diagnosed in the National Hospital Edgardo Rebagliati Martins during the period 2010-2017. No sampling was done, we worked with the entire population that met the selection criteria because it is small and accessible. The patients' clinical histories were reviewed, obtaining information about the time in months of survival, ILM, as well as sociodemographic, clinical and laboratory variables. Results: 121 patients with LCGBD were included in the analysis; of them, 57% were female and 66.1% were older than 60 years. According to the Zubrod Status, 66.5% corresponded to the degree of better prognosis and 59.5% presented associated B symptoms. About 60% were diagnosed in stages I and II and 57% presented extranodal involvement. The bivariate analysis with the Cox proportional hazards model showed that the ILM <2 constituted a predictor of the overall survival of the LCGBD (p = 0.011), estimating HR = 2.2 (95% CI: 1.2-4.1); likewise, an ILM <1.7 was also a predictor (p = 0.009) with an estimated HR = 2.2 (95% CI: 1.2-4.1). ILM <2.7 was not a predictor of overall survival.. Conclusion: The ILM could be used as a prognostic index because it is a predictor of the overall survival of patients with LCGBD of the Edgardo Rebagliati Martins National Hospital.

ABSTRACT

ABSTRACT CONTEXT: Splenic diffuse red-pulp small B-cell lymphoma is a rare disease, representing less than 1% of all non-Hodgkin lymphomas (NHL). This entity is characterized by involvement of bone marrow sinusoids and peripheral blood. The majority of cases are at an advanced stage when diagnosed. Its pathogenesis is still poorly understood. CASE REPORTS: We report on two patients with chronic non-replicating hepatitis B virus (HBV) who developed splenic diffuse red-pulp small B-cell lymphoma. Both of them were in stage IV at diagnosis and evolved with aggressive disease. Both of them achieved a complete response through chemotherapy, but one of them died due to infectious complications during bone marrow transplantation. The other decided not to undergo transplantation and continues not to show any evidence of disease today (three years after treatment). Some studies have shown a possible association between B-cell NHL and HBV. Nonetheless, the mechanism through which this oncogenic virus interacts with B-cell NHL is still poorly understood. HBV is lymphotropic and may insert into the host's genome, thus causing overexpression of oncogenes and downregulation of tumor suppressor genes. Therefore, chronic stimulation by HBV can increase B-cell proliferation, which promotes monoclonal expansion of these cells and results in malignancy. CONCLUSION: HBV may be implicated in the pathogenesis of this lymphoma, although no direct association between these two entities could be proved in the present study. Further investigations are necessary.


RESUMO CONTEXTO: Linfoma esplênico difuso da polpa vermelha, de linfócitos B pequenos, é uma doença rara, representando menos do que 1% de todos os linfomas não Hodgkin. Essa entidade é caracterizada por envolvimento de sinusoides da medula óssea e sangue periférico. A maioria dos casos está em estádio avançado ao diagnóstico. Sua patogênese ainda é pouco compreendida. RELATOS DE CASOS: Reportamos dois pacientes com vírus da hepatite B (HBV) crônica não replicante que desenvolveram linfoma esplênico difuso da polpa vermelha, de linfócitos B pequenos. Ambos estavam em estádio IV ao diagnóstico e evoluíram com doença agressiva. Ambos alcançaram resposta completa com a quimioterapia, porém um deles evoluiu a óbito por intercorrências infecciosas durante o transplante de medula óssea e o outro optou por não realizar o transplante e encontra-se sem evidência de doença até os dias atuais (três anos após tratamento). Alguns estudos demonstraram a possível associação entre linfomas não Hodgkin B e HBV. Entretanto, o mecanismo pelo qual esse vírus oncogênico interage com linfoma não Hodgkin B ainda é pouco compreendido. HBV é linfotrópico e pode se inserir no genoma do receptor, causando superexpressão de oncogenes e downregulation de genes supressores tumorais. Portanto, o estímulo crônico pelo HBV pode aumentar a proliferação de células B, promovendo expansão monoclonal dessas células, resultando em malignidade. CONCLUSÃO: HBV pode estar implicado na patogênese desse linfoma, entretanto, uma associação direta entre essas duas entidades não pôde ser provada no presente estudo e investigações adicionais são necessárias.

ABSTRACT

Fundamento: el síndrome de Sjögren es una enfermedad crónica autoinmune, de causa multifactorial, que se caracteriza por infiltración de las glándulas exocrinas con manifestaciones de sequedad de mucosas, así como otras manifestaciones sistémicas; su evolución y pronóstico son relativamente favorables, pero en ocasiones suele asociarse a procesos oncoproliferativos. Mantener un seguimiento estricto de estos pacientes es de vital importancia. Objetivo: conocer la asociación entre síndrome de Sjögren y linfoma no Hodgkin de células B grandes y difusas. Caso Clínico: paciente femenina, de 45 años de edad, con antecedentes síndrome de Sjögren, que acude a consulta donde refiere manifestaciones clínicas que permiten realizar el diagnóstico de linfoma no Hodgkin de células B grandes y difusas. Conclusiones: el síndrome de Sjögren, a pesar de tener una evolución favorable, puede asociarse, con relativa frecuencia, a procesos linfoproliferativos que ponen en peligro la vida del paciente. Se hace necesaria la búsqueda constante de elementos de sospecha de procesos tumorales en los pacientes con síndrome de Sjögren, como son la disminución brusca del factor reumatoide, la presencia de anticuerpos positivos de forma permanentes o la aparición de un síndrome seco que no responde al tratamiento.


Background: Sjögren´s syndrome is a chronic autoimmune disease. Its causes are multifactorial. It is characterized by infiltration in exocrine glands with mucosae dryness as well as other systemic manifestations. Its evolution and diagnosis are relatively favorable, although sometimes it is associated with developing cancer processes. Consequently, to carry a strict follow-up of these patients is of vital importance. Objective: to know the association between Sjögren´s syndrome and diffuse large B-cell Non-Hodgkin´s lymphoma. Clinical case: a forty-five year old female patient, with preceding Sjögren´s syndrome, who attended consultation. She had clinical manifestations that allowed the doctor to make the diagnosis of diffuse large B-cell Non-Hodgkin´s lymphoma. Conclusions: despite the disease has a favorable development, it can be frequently associated with proliferating lymphoma processes, which risk the patient´s life. It is necessary to search constantly for suspicious signs of tumors in patients with Sjögren´s syndrome, like sudden decrease in rheumatoid factor, the presence of permanent positive antibodies, or appearance of dry syndrome which do not respond to treatment, among others.

ABSTRACT

Los linfomas mediastinales anteriores pueden hacer parte del linfoma sistémico y comprenden aproximadamente el 50 % de los tumores mediastinales. El linfoma no Hodgkin primario del mediastino es un subtipo de menor prevalencia, representando un 10 % de los casos; este tiene dos subtipos histológicos que son el linfoma T linfoblástico y el linfoma B difuso de célula grande. Este último es agresivo y tiende a infiltrar la pleura, las estructuras óseas y el pulmón; se origina de las células B de la médula del timo. En este artículo se describe un caso de linfoma no Hodgkin primario del mediastino del subtipo B difuso de células grandes, sus hallazgos por imágenes, patología y una breve revisión de la literatura.


Anterior mediastinal lymphomas may be part of systemic lymphoma and they comprise approximately 50 % of mediastinal neoplasms. Primary non-Hodgkin's lymphoma of the mediastinum is a subtype with lower prevalence, representing 10 % of all cases; it has two histologic subtypes that include T-cell lymphoblastic lymphoma and diffuse large B-cell lymphoma. The latter is an aggressive neoplasm that tends to infiltrate the pleura, bone structures and the lung; it originates from thymic medullary B cells. This article presents a case of primary non-Hodgkin's lymphoma of the mediastinum with diffuse large B-cell subtype, its radiologic findings, pathology and a brief review of the literature.

ABSTRACT

Objetivos: Describir las características clínicas y los resultados del tratamiento inicial de los pacientes con linfoma de células del manto atendidos en el Instituto Nacional de Cancerología (INC) entre los años 2007 y 2011. Métodos: Estudio descriptivo y retrospectivo, tipo serie de casos basado en fuentes secundarias institucionales. Resultados: Se incluyeron 41 pacientes con una edad promedio de 60,5 años (DE ±10,5) y que tenían en su mayoría un estado funcional adecuado. La mayor parte tenía enfermedad avanzada al momento de la presentación (85%). El compromiso de la médula ósea y la afectación extranodal fueron frecuentes, encontrándose en 73% y 39% respectivamente. El diagnóstico histopatológico de la malignidad se realizó en tejido ganglionar en la mayoría de los casos (56%). Los esquemas de quimioterapia de primera línea empleados con más frecuencia fueron R-CHOP y R-HyperCVAD, en 37% y 29% de los casos respectivamente. Tras la quimioterapia de primera línea se logró alcanzar una respuesta completa en 64% de los pacientes, la mediana de duración de la primera remisión fue 9 meses (RIQ0,9 - 15). La neutropenia febril fue una complicación común presentándose en 42% de los casos. Dieciocho individuos recibieron quimioterapia de segunda línea, los esquemas más frecuentemente empleados fueron R-DHAP y R-HyperCVAD. Conclusiones: Las características clínicas de los pacientes son similares a las descritas en series de referencia. Las tasas de respuesta completa y la duración de la primera remisión son inferiores a las publicadas por otros grupos con esquemas similares de tratamiento. © 2014 Instituto Nacional de Cancerología.


Objective: To describe the clinical features and the treatment results achieved with the initial therapy among patients with mantle cell lymphoma treated at the National Cancer Institute (INC) between 2007 and 2011. Methods: Descriptive study, based on secondary institutional sources. Results: A total of 41 patients were included, with a mean age of 60.5 years (Standard deviation SD ± 10.5) and a good functional status. Most of them had advanced disease at initial presentation (85%). Bone marrow involvement and extra-nodal disease were frequent, as they were seen in 73% and 39% of the patients, respectively. Histopathological diagnosis of the malignancy was mainly made on lymph node tissue (56%). First line chemotherapy regimens used with an increased frequency were R CHOP and R- HyperCVAD, in 37% and 29% of the cases, respectively. After first line therapy, a complete response was achieved in 64% of the patients, median duration of the first remission was 9 months (Interquartile range IQR 0.9 - 15). Febrile neutropenia was a frequent complication, seen in 42% of the cases. Eighteen individuals received a second line of chemotherapy, with R DHAP and R HyperCVAD being the regimens most commonly administered. Conclusions: The clinical features of the patients are similar to those described in larger series of patients with the disease described elsewhere. The rate of complete responses, as well as the duration of the first remission after chemotherapy, is inferior when compared with the results of other groups that used similar treatment regimens.

ABSTRACT

Primary cutaneous lymphomas have different clinical behavior and prognosis than systemic lymphomas of similar histological subtype. About 30% of non-Hodgkin lymphomas involve extranodal tissues, the skin being the second most affected body organ after the gastrointestinal tract (approximately 18%). According to the EORTC (European Organization for Research and Treatment of Cancer) classification, the lymphoma centrofollicular is indolent, since the lesions increase in size slowly over the years and spread to extracutaneous sites is uncommon. Based on this, radiotherapy has been considered the treatment of choice by many studies. We present the case of a patient who had cutaneous centrofollicular scalp lymphoma for 1 year and showed good response to radiotherapy.


Os linfomas cutâneos primários têm comportamento clínico e prognóstico diferente dos linfomas sistêmicos de subtipo histológico semelhante. Cerca de 30% dos linfomas não-Hodgkin acometem tecidos extranodais, sendo a pele o segundo órgão mais envolvido após o trato gastrointestinal (aproximadamente 18%). De acordo com a classificação EORTC (European Organization for Research and Treatment of Cancer), o linfoma centrofolicular cutâneo é indolente, uma vez que as lesões aumentam de tamanho lentamente ao longo dos anos e a disseminação para sitios extracutâneos é incomum. Com base nisso, a radioterapia tem sido apontada como o tratamento de primeira escolha por muitos estudos. Apresentamos um caso de paciente com linfoma cutâneo centrofolicular no couro cabeludo há 1 ano e que apresentou boa resposta à radioterapia.
