RESUMO

La especialidad de anatomía patológica juega un papel fundamental en el equipo multidisciplinario de los sistemas de salud, debido a que un grupo mayoritario de enfermedades son diagnosticadas mediante el estudio de los cambios ocasionados en las células, tejidos y órganos a niveles macroscópico y microscópico, circunscribiendo esta especialidad, de forma general, en: patología quirúrgica, citología y necropsias. Hoy en día, con el advenimiento de nuevas tecnologías al Perú, el ejercicio de la especialidad ha ampliado su actividad enormemente (Inmunohistoquímica, inmunofluorescencia, microscopía electrónica, patología molecular, entre otras).


The anatomic pathology specialty plays a fundamental role within the multidisciplinary health systems team, since the majority of diseases are diagnosed by studying changes in cells, tissues and organs at both the macro and microscopic levels. Thus, this specialty is generally circumscribed in: surgical pathology, cytology and necropsy. Today, with the advent of new technologies in Peru, the practice of the specialty has considerably expanded its activity (immunohistochemistry, immunofluorescence, electron microscopy, molecular pathology, among others).

RESUMO

El virus de Epstein Barr (VEB) es responsable del 10% del cáncer gástrico (CG) y se correlaciona con mejor tasa de sobrevida. En Perú, no existen estudios sobre prevalencia y características clínicas de CG VEB positivo. Objetivos: Determinar la prevalencia y las características clínico patológicas del CG VEB positivo. Materiales y métodos: 111 muestras de GC fueron examinadas centralmente por hibridización cromogénica in situ del RNA del VEB (EBER CISH). Resultados: El 8,4% de los casos fueron positivos para VEB. La mayoría de los casos VEB positivos tuvieron más de 60 años, varones y la localización, antro / píloro fue la más frecuente. La mayoría de los casos fueron de tipo intestinal y un patrón tubular con una tendencia a un mejor pronóstico en comparación con los casos de VEB negativo. Conclusión: CG VEB positivo es una entidad con una prevalencia de 8,4% en Perú con características clínicas y morfológicas distintivas.


Epstein Barr Virus (EBV) is responsible of 10% of Gastric Cancer (GC), correlating with better survival rates. In Peru, there were not studies about prevalence and clinical characteristics of CG EBV positive. Objective: Determine prevalence and clinicopathological characteristics of GC EBV positive. Materials and methods: 111 GC tumour samples were centrally screened by Chromogenic in situ hybridization (CISH) technique for EBV-encoded RNA (EBER) transcript. Results: 8.4% of cases were positive for EBV. Most cases EBV positive were more than 60 years old; male, antrum/pylorus had more frequent localizations. Most cases had an intestinal type and tubular patter and a tendency to better prognostic in comparison EBV negative cases. Conclusion: EBV positive GC is an entity with a prevalence of 8.4% in Peru with distinctive clinical and morphological characteristics.

RESUMO

INTRODUCTION: To address the lack of genomic data from Hispanic/Latino (H/L) patients with lung cancer, the Latino Lung Cancer Registry was established to collect patient data and biospecimens from H/L patients. METHODS: This retrospective observational study examined lung cancer tumor samples from 163 H/L patients, and tumor-derived DNA was subjected to targeted-exome sequencing (>1000 genes, including EGFR, KRAS, serine/threonine kinase 11 gene [STK11], and tumor protein p53 gene [TP53]) and ancestry analysis. Mutation frequencies in this H/L cohort were compared with those in a similar cohort of non-Hispanic white (NHW) patients and correlated with ancestry, sex, smoking status, and tumor histologic type. RESULTS: Of the adenocarcinomas in the H/L cohort (n = 120), 31% had EGFR mutations, versus 17% in the NHW control group (p < 0.001). KRAS (20% versus 38% [p = 0.002]) and STK11 (8% versus 16% [p = 0.065]) mutations occurred at lower frequency, and mutations in TP53 occurred at similar frequency (46% versus 40% [p = 0.355]) in H/L and NHW patients, respectively. Within the Hispanic cohort, ancestry influenced the rate of TP53 mutations (p = 0.009) and may have influenced the rate of EGFR, KRAS, and STK11 mutations. CONCLUSIONS: Driver mutations in H/L patients with lung adenocarcinoma differ in frequency from those in NHW patients associated with their indigenous American ancestry. The spectrum of driver mutations needs to be further assessed in the H/L population.

RESUMO

Presentamos el caso de una paciente de 40 años, en edad fértil que inicio con un cuadro clínico abdominal obstructivo, la laparoscopia diagnóstica reveló una tumoración ileal de aspecto estenosante, se hace la resección intestinal y en el estudio histopatológico se encontró epitelio endometrial y estroma del endometrio confirmando el diagnóstico de endometriosis ileal. Se hace la revisión de esta patología. En pacientes jóvenes, sin cirugías previas y con antecedentes de períodos menstruales dolorosos asociados a distensión abdominal y alteración del ritmo defecatorio, debe incluirse la endometriosis en el diagnóstico diferencial de una obstrucción intestinal.


We report the case of a patient of 40 years, in childbearing age with clinical abdominal obstruction, diagnostic laparoscopy revealed an ileal stenosing tumor , after intestinal resection their histopathological study found endometrial epithelium and stroma confirming the diagnosis of endometrial ileal endometriosis. It is the revision of this pathology. In young patients without previous surgery and with a history of painful periods bloating associated with defecation rhythm alteration, endometriosis should be included in the differential diagnosis of intestinal obstruction.

RESUMO

GOAL: Milk-based formulas can induce cow's milk protein allergy (CMPA) in infants. This article discusses two cases of severe CMPA in infants exposed to casein-based formulas. CASES: Case N°1: A 7 day old boy developed diarrhea with no improvement despite several courses of antibiotic and switching to formula without lactose. At 2 months of age he had a hemoglobin 8.6 mg/dL, IgE = 17.8 IU/ml (normal <1.5 UI/ml) and a CD4/CD8 ratio = 0.16 (normal 1.5 ­ 2.5). Upper endoscopy biopsies showed duodenal atrophy. He received a casein hydrolysate formula with decreased fecal flow but continued diarrhea. At 3 months of life he was changed to an amino acid formula with cessation of diarrhea in < 48 hours, resumption of normal growth and normalization of duodenal histology. Case N°2: A 10 month old boy had a 6-day history of vomiting, diarrhea and edema. His albumin was 2.35 mg/dL. An upper endoscopy biopsy showed severe duodenal atrophy. He received a casein hydrolysate with good tolerance and resolution of the edema. At 26 months of age, and endoscopic duodenal biopsy showed regeneration of the mucosa. CONCLUSION: The CMPA is a frequent diagnosis in young infants that can be confused with infection. An early diagnosis is key to a positive outcome.

RESUMO

OBJETIVO: El uso de fórmulas maternizadas puede causar alergia a la proteína de leche de vaca (ALPLV). Se discuten dos casos de ALPLV en infantes. CASOS: Caso N°1: Niño que presentó diarreas desde los 7 días de vida, sin mejoría a pesar de varios cursos de antibióticos y uso de fórmula sin lactosa. A los dos meses tenía anemia (8.6mg/dL), además de IgE de 17.8 UI/ml (normal <1.5 UI/ml) y una relación CD4/CD8 = 0.16, (normal 1.5 û 2.5). Endoscopía mostró atrofia duodenal. Recibió una fórmula a base de hidrolizado extenso de caseína, con mejoría parcial. A los tres meses de vida se le cambió a fórmula a base de aminoácidos cesando la diarrea en < 48 horas, retomando crecimiento normal y normalizando la histología duodenal. Caso Nº2: Niño que debutó a los 10 meses de edad con un cuadro de 6 días caracterizado por vómitos, diarreas, y anasarca. Presentó hipoalbuminemia (2.35mg/dL). Una endoscopía mostró atrofia duodenal severa. Recibió hidrolizado extenso de proteínas con resolución de los edemas. Biopsia duodenal control a los 2 años y dos meses de vida evidenció regeneración de la mucosa. CONCLUSION: La ALPLV es un diagnóstico que se debe plantear precozmente para un manejo exitoso.

RESUMO

La positividad al HER2 se plantea como un factor pronóstico negativo en Cáncer Gástrico (CG), correlacionando con pobres tasas de sobrevida. Los reportes de tasas de positividad al HER2 en CG varían ampliamente (6-35%). El objetivo del estudio fue determinar la tasa de positividad y describir las características clínicas y patológicas de los CG Her2(+). Los tumores CG fueron centralmente screneados para inmunohistoquímica y FISH. 9% de loscasos fueron positivos, encontrándose mayor positividad en los estadios avanzados (III/ IV) vs. los estadios tempranos (I/II)(p= 0.045); en el tipo histológico intestinal vs. mixto/ difuso ( p=0.03 ) y en los cánceres de la unión gastroesofágica vs CG ( p=0.005).


HER2 positivity is thought to be a negative prognostic factor in gastric cancer (GC), correlating with poor survival rates. Reported HER2-positivity rates in GC have varied widely (6-35%).Objetive of this study is to determine rate of positivity and describe clinical and pathological characteristics of HER-2(+) GC. 100 GC tumour samples were centrallyscreened by immunohistochemistry and FISH. 9% of cases were positive . More positivity HER2 was found in advanced stages (III/IV) vs. early stages (I/II)(p=0.045) ; intestinal histology subtype vs diffuse/ mixed (p=0.045) and gastro-oesophageal junction cancervs GC ( p=0.005).

RESUMO

A 30-yr-old woman was admitted with acute headache, right hypesthesia and hemiparesis, right quadrantanoptic defect and neck stiffness. CT imaging study revealed left temporal hematoma and angio CT and cerebral digital angiography revealed and aneurysm of the left posterior cerebral artery. The patient was treated surgically. Surprisingly the clot was very firm and consistent with a mixture of tumor tissue and blood debris and in the pathological examination turned to be a glioblastoma multiforme. The aneurysm was clipped. The partner gradually improved and was treated with linear accelerator radiotherapy. This rare case is consistent with the association of malignant tumor with an aneurysm of neoplasm type.

RESUMO

Se reporta el caso de un paciente varón de 69 años con un gran adenoma de las glándulas de Brunner que se presentó con anemia severa sintomática y pérdida de peso significativa. El estudio endoscópico alto detectó una gran tumoración duodenal que se extendía del bulbo hasta la segunda porción y la biopsia fue informada como duodenitis crónica inespecífica con cambios metaplásicos gástricos. El paciente fue sometido a una duodenopancreatectomía y la histología de la pieza quirúrgica fue un tumor de glándulas de Brunner. El adenoma de glándulas de Brunner se considera un tumor benigno del duodeno; sin embargo, la resección endoscópica está limitada a lesiones menores.


We report the case of a 69-year-old male patient with a large Brunner's gland adenoma, who presented with symptomatic anemia and significant weight loss. The upper gastrointestinal endoscopy showed a large duodenal tumor extending form the bulb to the second portion, and the biopsy was reported as chronic non-specific duodenitis with gastric metaplastic changes. The patient underwent a duodenopancreatectomy, and the histological study of the surgical specimen was reported as a Brunner's gland tumor. Brunne's gland adenoma is considered a benign tumor of the duodenum; however, endoscopic resection is restricted to minor injuries.

RESUMO

Introducción: El virus del papiloma humano (VPH) es un agente involucrado en la patogénesis del cáncer de cérvix. Varios reportes describen una asociación entre VPH y carcinoma escamoso de esófago (CEE). Objetivo: determinar la frecuencia de infección del PVH de alto riesgo y el CEE. Material y método: se realizó un estudio retrospectivo del universo de caso, n= 29 de CEE diagnosticados del 2003 al 2006 con estudio anatomopatológico en el Hospital Edgardo Rebagliati Martins, Lima, Perú. La muestras parafinadas fueron sometidas a PCR-RT para la detección de PVH 16,18,31,33 y 45 . Resultados: la edad media fue de 73 años, la relación masculino/femenino fue 3. Los estadios fueron : estadio I :1 caso; estadio II: 12 casos, estadio III:14 casos y estadio IV: 2 casos. No se detectó en ningún caso VPH de alto riesgo a pesar de emplear dos sondas diferentes. Conclusión: el VPH no fue detectado en CEE en el universo de casos estudiados.


Introduction: Human papilloma virus (HPV) is an agent involved in the pathophysiology of cervical cancer. Many reports describe an association between HPV and esophageal squamous-cell carcinoma (ESCC). Objective: The main objective of the study is to determine the frequency of high-risk HPV infection and ESCC. Material and method: A retrospective study including 29 ESCC cases with a histological and pathological diagnosis from 2003 to 2006 in Edgardo Rebagliati-Martins Hospital in Lima, Peru. Paraffin-mbedded tissue fragments underwent RT-PCR tests for detecting HPV types 16, 18, 31, 33, and 45. Results: Mean age of patients was 73 years, male to female ratio was 3. Stage I disease was found in one case; stage II disease in 12 cases, stage III disease in 14 cases, and stage IV in 2. No highrigh HPV was found in any of the samples studied, even though we used two different probes. Conclusion: HPV was not detected in ESCC in the population studied.

RESUMO

Introducción: las características clínicopatológicas de los linfomas malignos varían de acuerdo a la geografía. La piel es el segundo lugar de compromiso extranodal de linfoma no Hodgkin .El linfoma primario cutáneo tienen un comportamiento clínico y pronóstico diferente de los linfomas sistémicos Objetivo: el objetivo de este estudio fue determinar la frecuencia relativa de los linfomas cutáneos y examinar la relevancia clínica de la nueva clasificación WHO/EORTC y la sobrevida de los casos peruanos de linfoma primario cutáneo. Material y método: se realizó un estudio retrospectivo clínicopatológico de 78 casos de linfomas cutáneos, diagnosticados desde 1997 al 2004 en el Hospital Edgardo Rebagliati Martins, Essalud, Lima,Perú. Las historias clínicas, biopsias y pruebas de inmunohistoquímica de los 78 pacientes enrolados fueron revisadas. Resultados: 67/78 (85,9%) fueron linfomas primarios cutáneos y 11/78 (14,1%) fueron linfomas cutáneos secundarios. El linfoma secundario cutáneo más frecuente fue el linfoma /leucemia T del adulto (ATLL) con 72% de los casos. El linfoma primario cutáneo más frecuente fue la micosis fungoide (MF) 30/67 (44,7%) , seguido del ATLL 13/67 (19,4%) y el linfoma T periférico no especificado 4/67 (6%). La sobrevida a 5 años para la MF, ATLL cutáneo y ATLL sistémico fue de 77%. 18% y 0% respectivamente. Conclusión: MF y ATLL cutáneo fueron los linfomas primarios cutáneos más frecuentes en nuestro hospital. La MF posee un buen pronóstico mientras el ATLL cutáneo posee pobre sobrevida.


Introduction: Clinico-pathological features of malignant lymphomas vary according to geography. The skin is the second site for extranodal Non-Hodgkin Lymphoma. Primary cutaneous lymphoma has a different clinical behavior and prognosis compared with systemic lymphomas. Objective: The aim of this study was to determine the relative rate of cutaneous lymphomas and to examine the clinical relevance of the new WHO/EORTC classification and survival in Peruvian persons with primary cutaneous lymphoma. Methods: We conducted a clinico-pathological retrospective study in 78 cases of cutaneous lymphoma diagnosed between 1997 and 2004 in a National General Hospital. Clinical records, hematoxylin & eosin-stained slides and immunohistochemical studies from 78 patients with malignant lymphoma of the skin were reviewed. Results: 67/78 cases (85,9%) were primary cutaneous lymphomas and 11/78 (14,1%) were secondary cutaneous lymphomas. Most frequent secondary cutaneous lymphoma was systemic adult T-cell lymphoma/Leukemia (ATLL), accounting for 72% of cases. Most frequently found primary cutaneous lymphoma were mycosis fungoides (MF), in 30/67 (44,7%) patients, cutaneous ATLL in 13/67 (19,4%), and non-specific peripheral T-cell lymphoma in 4/67 (6%). 5-year survival rates for MF, cutaneous ATLL and systemic ATLL were 77%, 18%, and 0%, respectively.Conclusions: MF and ATLL are the more frequently found primary cutaneous lymphomas in our hospital. MF has a good prognosis, while cutaneous ATLL has a poor survival rate.

RESUMO

El Síndrome Antifosfolipídico es una entidad adquirida y multisistémica, caracterizada por hipercoagulación, en la que las manifestaciones cutáneas, en un alto porcentaje, permiten sospechar su diagnóstico; estas se caracterizan por livedo reticularis y los diferentes grados de necrosis cutánea dependiendo de los vasos afectados, además de otros hallazgos importantes como son la trombocitopenia y los antecedentes de abortos. Los marcadores serológicos son los anticuerpos antifosfolipidicos que corresponden al anticoagulante lupico y a la anticardiolipina.


Antiphospholipidic syndrome is an acquire and multisystemic entity, whose principal feature is the hypercoagulability; the cutaneous lesions are livedo reticularis and different types of skin necrosis, that depends on venous or arterial or both thrombosis, another signs are thrombocytopenia and history of aborts. Laboratory serologic markers are antiphospholipidic antibodies such us lupic anticoagulant and anticardiolipin.

RESUMO

Las neoplasias de ampolla de Vater son lesiones poco frecuentes, la ampulectomía consiste en la resección total de la ampolla de Vater y parte de la pared duodenal con la posterior reconstrucción y anastomosis de los conductos colédoco y Wirsung al duodeno. La resección local de la ampolla es una alternativa a la duodenopancreatectomía, que tiene que ser tomada en cuenta, sobre todo en lesiones benignas como son los casos de adenomas de la ampolla de Vater. Aquí se describen dos casos. El primero se trata de un adenoma de ampolla de Vater que luego de la ampulectomía presentó bordes comprometidos en la biopsia de congelación y terminó en una duodenopancreatectomía y el segundo caso se trata de un lifangioma de ampolla que no presento compromiso del borde de sección y luego de la ampulectomía no requirió mayor tratamiento.
