Fascitis necrosante como causa de muerte en trauma de recto. Reporte de caso / Necrotizing fasciitis as a cause of death in rectal trauma. Case report

Introducción. La perforación del recto por trauma cerrado es poco frecuente y se asocia a fracturas pélvicas. En pacientes con perforaciones de recto no traumáticas se ha reportado fascitis necrosante en miembros inferiores, en la mayoría de los casos asociada a alta mortalidad. Caso clínico. Hombre de 36 años con trauma cerrado abdomino-pélvico y perforación de recto inferior, quien recibió manejo quirúrgico mediante derivación intestinal y fijación pélvica. Evolucionó con hematoma escrotal sobreinfectado, inestabilidad hemodinámica, signos de fascitis necrosante y choque séptico 4 días posterior a su ingreso. Resultados. Se tomó muestra para cultivo del hematoma escrotal que reportó E. coli. La patología del desbridamiento escrotal informó necrosis de coagulación en toda la muestra. Conclusión. El tacto rectal debe realizarse siempre ante la presencia de enfisema subcutáneo al examen físico o en la tomografía, para un diagnóstico temprano y manejo quirúrgico multidisciplinario oportuno, según el caso. La presencia de enfisema subcutáneo debe aumentar la sospecha de perforación de recto. Hay pocos reportes de fascitis secundaria a perforación de recto por trauma cerrado, por lo que no se conoce con precisión la mortalidad asociada.

Introduction. Rectal perforation due to blunt trauma is rare and associated with pelvic fractures. Signs of necrotizing fasciitis in lower limbs have been reported in non-traumatic rectal perforations, in most cases associated with high mortality. Case report. A 36-year-old man presents blunt abdomino-pelvic trauma and perforation of the lower rectum. Surgical management by intestinal diversion and pelvic fixation is performed. 4 days after admission, evolves with over-infected scrotal hematoma, hemodynamic instability, signs of necrotizing fasciitis and septic shock. Results. A sample for culture was taken from a scrotal hematoma that reported E. coli. Pathology of scrotal debridement reported coagulation necrosis in the entire specimen. Discussion. Digital rectal examination should always be performed in the presence of subcutaneous emphysema on physical examination or CT scan for early and multidisciplinary diagnosis and surgical management as appropriate. Conclusion. The presence of subcutaneous emphysema should raise the suspicion of rectal perforation. There are few reports of rectal perforation due to blunt trauma and fasciitis, so the associated mortality is not precisely known.

Nodular fasciitis: a benign mimicker of soft tissue malignancies / Fascitis nodular: un imitador benigno de las neoplasias malignas de tejidos blandos

La fascitis nodular es una masa subcutánea, benigna, autolimitada, que puede simular un sarcoma de tejidos blandos en su presentación clínica e histopatológica. Debido a que la mayoría de las descripciones de esta condición provienen de pacientes caucásicos, es necesario enfatizar su existencia en poblaciones poco representadas en la literatura. Se presenta el caso de un paciente mexicano, masculino, de 49 años, quien fue inicialmente mal diagnosticado y tratado como quiste epidérmico. Tras la recurrencia de la lesión, se realizó una adecuada técnica de biopsia y estudios de imagen, confirmando el diagnóstico de fascitis nodular. El presente reporte resalta la importancia de abordar con cautela las masas subcutáneas que puedan simular tanto tumores benignos como malignos para mejorar el pronóstico de los pacientes.

Nodular fasciitis is a benign, self-limited, subcutaneous tumor that may resemble a soft tissue sarcoma both clinically and histopathologically. Since most descriptions derive from Caucasian patients, further awareness is necessary in underrepresented populations. Here, we present a case of nodular fasciitis in a 49-year-old Mexican male who had been misdiagnosed and mistreated as an epidermal cyst. After recurrence, an adequate biopsy and imaging studies confirmed the diagnosis of nodular fasciitis. This case illustrates the importance of properly studying subcutaneous masses that can mimic a wide array of benign and malignant tumors to improve overall patient prognosis.

Infecciones graves de huesos, articulaciones y tejidos blandos adquiridas en la comunidad / Severe community-acquired bone, joint, and soft tissue infections

Introducción: Las infecciones de huesos, articulaciones y partes blandas, no solo han tenido una incidencia creciente en los últimos años en el Hospital Pediátrico Universitario Paquito González Cueto de Cienfuegos, sino también una evolución más grave. Objetivo: Describir aspectos clínicos y epidemiológicos de las infecciones graves de tejidos blandos, huesos y articulaciones. Métodos: Se revisó la base de datos computadorizada del Departamento de Estadística del Hospital Pediátrico Paquito González, para identificar todos los egresos de la Unidad de Cuidados Intensivos Pediátricos, con diagnóstico de celulitis o absceso de tejidos blandos, fascitis, miositis, osteomielitis, sepsis severa y shock séptico, en el periodo de enero de 2009 a diciembre de 2019. Se estudiaron las siguientes variables: localización de la infección de piel y tejidos blandos, grupo de edad, año del egreso y sitio de origen de la sepsis. Resultados: No hubo diferencias en la incidencia entre los grupos de edad. La celulitis de los miembros fue la forma clínica más frecuente. Se encontró una incidencia creciente de las infecciones de tejidos blandos. Las infecciones de huesos y articulaciones, representaron el segundo sitio de origen más frecuente de sepsis grave y el shock séptico. Conclusiones: Ha habido un aumento de las infecciones de piel y tejidos blandos que requieren ingreso en la unidad de cuidados intensivos del citado hospital en los últimos 11 años. Estas infecciones de conjunto con las infecciones de huesos y articulaciones, constituyen un problema de salud puesto que provocan sepsis grave y shock séptico con una incidencia significativa(AU)

Introduction: Infections of bones, joints and soft parts have not only had an increasing incidence in recent years at ¨Paquito González Cueto¨ University Pediatric Hospital in Cienfuegos, but also a more serious evolution. Objective: Describe clinical and epidemiological aspects of severe soft tissues, bones and joints infections. Methods: The computerized database of the Department of Statistics of ¨Paquito González¨ Pediatric Hospital was reviewed to identify all discharges from the Pediatric Intensive Care Unit with a diagnosis of cellulite or soft tissue abscess, fasciitis, myositis, osteomyelitis, severe sepsis and septic shock, in the period from January 2009 to December 2019. The following variables were studied: location of skin and soft tissue infection, age group, year of discharge, and sepsis origin location. Results: There were no differences in the incidence between age groups. Limb cellulite was the most common clinical form. An increasing incidence of soft tissue infections was found. Bone and joint infections represented the second most frequent origin location of severe sepsis and septic shock. Conclusions: There has been an increase in skin and soft tissue infections that require admission to the intensive care unit of the aforementioned hospital in the last 11 years. These infections, together with bone and joint infections, constitute a health problem since they cause severe sepsis and septic shock with a significant incidence(AU)

Papillary thyroid carcinoma with nodular fasciitis-like stroma: a rare variant

Papillary thyroid carcinoma with desmoid-type fibromatosis (PTC-DTF) or nodular fasciitis-like stroma (PTC-NFS) is a rare morphological variant of PTC with a favorable prognosis. There is a paucity of molecular data regarding this entity. We present the case of a 20-year-old female who presented with a palpable mass over the anterior aspect of the neck for the past 3-4 months, which was diagnosed as PTC-NFS. Ultrasonogram of the neck revealed a bulky left lobe of thyroid that contained a well-defined heterogenous lesion measuring around 24 × 26 × 36 mm with involvement of the adjacent isthmus. She underwent a total thyroidectomy with central compartment lymph node dissection. Histological examination revealed a biphasic tumor with epithelial and stromal components resembling nodular fasciitis. Two dissected lymph nodes showed metastasis of the epithelial component only. On immunohistochemistry, BRAF mutant protein expression was evident in the epithelial component only, while β-catenin was negative in both the components. The histopathological diagnosis of papillary thyroid carcinoma with nodular fasciitis-like stroma was offered. Sanger sequencing revealed a BRAFV600E (c.1799T>A, Val600Glu) mutation. Post-operatively, no residual tumor was detected on ultrasound and radioiodine scans. The patient was doing well at follow-up of 9 months. PTC-NFS/DTF is a histological variant of PTC with a favorable prognosis. Our index case was associated with the BRAF mutation, which was restricted to the epithelial component. Thorough sampling of the excised specimen is essential in order not to miss the epithelial component, which, in most reported cases (including ours) appears to be small.

Fasceíte necrotizante cervical: relato de caso / Cervical necrotizing fasciitis: case report

Introdução: A Fasceíte Necrotizante Cervical é uma infecção rara, geralmente com evolução rápida e progressiva da fáscia superficial e do tecido adiposo subcutâneo. Pode se desenvolver a partir de uma infecção odontogênica que se dissemina para os planos faciais e profundos. O presente trabalho tem por objetivo relatar um caso clínico de uma paciente do gênero feminino, 49 anos de idade, atendida na Emergência do Hospital Getúlio Vargas-PE, com quadro clínico sugestivo de Fasceíte Necrotizante Cervical de origem Odontogênica.

Eosinophilic fasciitis: an atypical presentation of a rare disease

SUMMARY Eosinophilic fasciitis, or Shulman's disease, is a rare disease of unknown etiology. It is characterized by peripheral eosinophilia, hypergammaglobulinemia, and high erythrocyte sedimentation rate. The diagnosis is confirmed by a deep biopsy of the skin. The first line of treatment is corticotherapy. We present a rare case of eosinophilic fasciitis in a 27-year-old woman with an atypical presentation with symmetrical peripheral edema and a Groove sign. The patient responded well to treatment with corticosteroids at high doses and, in this context, was associated with hydroxychloroquine and azathioprine. After two and a half years, peripheral eosinophilia had increased, and more of her skin had hardened. At that time, the therapy was modified to include corticoids, methotrexate, and penicillamine. It is of great importance to publicize these cases that allow us to gather experience and better treat our patients.

RESUMO A fasciite eosinofílica ou doença de Shulman é uma doença rara de etiologia desconhecida. É caracterizada por eosinofilia periférica, hipergamaglobulinemia e velocidade de sedimentação eritrocitária elevada. O diagnóstico é confirmado por biópsia profunda da pele. O tratamento de primeira linha é a corticoterapia. Apresentamos um caso raro de fasciite eosinofílica numa mulher de 27 anos com uma apresentação atípica com edema periférico simétrico e sinal de Groove. A paciente respondeu bem ao tratamento com corticoides, mas em doses elevadas, e, nesse contexto, associou-se hidroxicloroquina e azatioprina. Ao fim de dois anos e meio verificou-se aumento de eosinofilia e novamente pele mais endurecida. Nessa altura alterou-se a terapêutica para corticoides, metrotexato e penicilamina. É de grande importância a divulgação desses casos que nos permitem reunir experiência e assim melhor tratar os nossos doentes.

Manejo diagnóstico-terapéutico de las lesiones mamarias atípicas / Diagnostic-therapeutic Management of Atypical Breast Lesions

Las lesiones mamarias se dividen histológicamente en dos grandes grupos, malignas y benignas. Las lesiones malignas pueden ser de origen ductal o lobulillar, siendo el carcinoma ductal infiltrante la neoplasia invasiva más frecuente. Las lesiones benignas se clasifican en no proliferativas, proliferativas sin atipias y proliferativas con atipias. Dentro de los dos últimos grupos se encuentran entidades que conllevan un alto riesgo de desarrollar carcinoma de mama, como pueden ser la hiperplasia ductal atípica, la cicatriz radial o la neoplasia lobular. Revisamos en qué consisten dichas entidades y cuáles son sus características principales en imagen, fundamentalmente en mamografía y ecografía. Si tras realizar una biopsia se obtiene uno de esos diagnósticos histológicos, es importante analizar las características imagenológicas y el tipo de procedimiento realizado (número de cilindros obtenidos, calibre de aguja...), para realizar un adecuado manejo posterior. En algunos casos la actitud a seguir será la extirpación quirúrgica completa de la lesión, mientras que en otros se podrá realizar una extirpación percutánea (mediante biopsia con aguja de vacio), o incluso seguimiento estricto por imagen. Mediante diferentes casos mostraremos nuestra experiencia y analizaremos la literatura vigente para recordar esas entidades y llegar a un consenso adecuado sobre el manejo de las mismas.

Breast lesions are divided histologically into two large groups, malignant and benign. Malignant lesions may be of ductal or lobular origin, with infiltrating ductal carcinoma being the most frequent invasive neoplasm. Benign breast lesions are classified as proliferative, proliferative without atypia and proliferative with atypia. Within the last two classifications are entities that carry a high risk of developing breast carcinoma, such as atypical ductal hyperplasia, radial scar or lobular neoplasia. We review what these entities consist of and what are their fundamental characteristics in image, fundamentally in mammography and ultrasound. When we perform one of these histological diagnoses after a biopsy, it is important to analyze the radiological characteristics and the type of procedure performed (number of cylinders, needle gauge ...) to perform an appropriate posterior management. In some cases the attitude to be followed will be the complete surgical removal of the lesion, while in others a percutaneous excision (through vacuum needle biopsy) or even strict image follow-up may be performed. Through different cases we will show our experience and analyze current literature to remember these entities and reach an adequate management consensus.

Fascitis eosinofílica: reporte de un caso / Eosinophilic fasciitis: a case report

RESUMEN La fascitis eosinofílica es una enfermedad rara del tejido conectivo que se caracteriza por induración y engrosamiento progresivo y simétrico de la piel y del tejido celular subcutáneo localizado, principalmente, en las extremidades. Además de las manifestaciones cutáneas hay compromiso articular, muscular y, en casos excepcionales, compromiso sistémico. Su diagnóstico se basa en los hallazgos clínicos, eosinofilia en sangre periférica y la toma de una biopsia profunda de piel, que incluya la fascia donde se evidencia un infiltrado compuesto por linfocitos y eosinófilos. El tratamiento de elección son los esteroides sistémicos acompanados de medicamentos inmunosupresores.

ABSTRACT Eosinophilic fasciitis is a rare connective tissue disease. It is characterised by a progressive and symmetrical induration and thickening of the skin and soft tissues of the limbs. In addition to the skin manifestations, the joints and muscles are also involved, and in rare cases there can be systemic involvement. The diagnosis of EF is based on clinical findings, the presence of peripheral blood eosinophilia, and a full-thickness biopsy that should include the deep fascia in order to show the inflammatory infiltration that is mostly composed of lymphocytes and eosinophils. Systemic corticosteroids remain the treatment of choice and may be combined with an immunosuppressive drug.

Injerto dermo-epidérmico como tratamiento del siliconoma de extremidad inferior / Dermoepidermal graft as treatment of lower extremity siliconoma

Resumen Introducción A pesar de la evidencia sobre los malos resultados y riesgos del uso de inyecciones subcutáneas de silicona para mejorar el contorno corporal, esta técnica sigue siendo utilizada por personas no calificadas. Caso clínico Paciente de 56 años quien consultó por cuadro de celulitis en pierna izquierda. Se obtuvo el antecedente de intervención con silicona en cara, dorso de las manos, glúteos y piernas el año 2000. El cuadro progresó con múltiples abscesos en la totalidad de la pierna y sepsis. Se realizaron aseos quirúrgicos exponiendo planos fascial y muscular, se utilizó terapia local con sistemas de presión negativa y posterior injerto dermo-epidérmico (IDE). El manejo multidisciplinario se realizó en unidades críticas. Los resultados del manejo fueron satisfactorios, salvando la extremidad con cobertura total, logrando el alta luego de 4 meses. Conclusión A pesar de conocerse los peligros de la inyección de silicona, este sigue siendo un procedimiento frecuente. En nuestra paciente se manifestó como fascitis de la pierna, requiriendo tratamiento quirúrgico agresivo. Conocer esta entidad, su diagnóstico y tratamiento es fundamental para tratar pacientes con complicaciones graves.

Introduction Despite the evidence of poor performance and risks of using silicone subcutaneous injections to improve body contour, this technique is still used by untrained people, generating an iatrogenic entity with serious complications. Case report 56 year old female presented left lower extremity cellulitis. A history of previous intervention with silicone injections in face, back of hands, buttocks and legs in year 2000 was obtained. An inflammatory process progressed locally and systemically with multiple abscesses, subcutaneous thickness in the entire leg and sepsis, requiring multiple surgical procedures, reaching fascial and muscle planes exposition of the left leg. The patient underwent local therapy with negative pressure systems and subsequent dermoepidermal graft. Multidisciplinary management was performed on a critical unit. The results were satisfactory, preserving the limb with full coverage. She was discharged after four months of inpatient management. Conclusion Despite knowing the risks of silicone injection (industrial or medical) it remains a common procedure. In our patient she presented as leg fasciitis, requiring aggressive surgical treatment. Knowing this entity, its diagnosis and treatment is essential to treat patients with serious complications.

Pyomyositis and fasciitis by carbapenem resistant microorganism in a patient with severe tophaceus gout / Piomiositis y fascitis asociadas a microorganismo resistente a carbapenémicos, en un paciente con gota tofácea severa

Abstract Pyomyositis, defined as a suppurative muscle infection, is a rare entity that is classified as tropical or non-tropical according to the geographical region. The case of a patient with a history of severe tophaceous gouty arthritis, coming from tropical wet climate in Colombia, who presented with suggestive cellulitis, with a torpid evolution despite standard dual management. An associated abscess was documented, and initially abscessed cellulitis and septic arthritis were suspected, the latter was finally ruled out, once teh muscle origin of the abscess becames evident by means of computed tomography and ultrasonography. Intraoperatively, an abscess with fascia involvement and intramuscular tophaceous disease was observed. Surgical drainage and repeated washes were required. Carbapenem resistant Klebsiella pneumoniae was isolated, requiring last-line Gouty arthritis antibiotic therapy for a prolonged period of time.

Resumen La piomiositis es una infección supurativa del músculo estriado, rara, que se clasifica según la región geográfica de presentación, en tropical y no tropical. Se presenta el caso de un paciente con antecedente de artritis gotosa tofácea severa, proveniente de zona tropical, quien comienza con cuadro sugestivo de celulitis, con evolución tórpida pese a manejo estándar dual; se documenta un absceso de ubicación no clara, sospechando en principio celulitis abscedada y artritis séptica, finalmente descartándose esta última y haciéndose evidente origen muscular del absceso por medio de tomografia computarizada y ultrasonografía. Quirúrgicamente se evidenció absceso con compromiso de fascia, enfermedad tofácea intramuscular; requirió drenaje quirúrgico y lavados, documentándose germen Klebsiella pneumoniae resistente a carbapenémicos, requiriendo antibioticoterapia de última línea por un periodo prolongado.

Eosinophilic fasciitis

Abstract Eosinophilic fasciitis is a rare sclerodermiform syndrome of unknown etiology. It is characterized by the thickening of the muscular fascia and subcutaneous tissue, with a variable infiltration of eosinophils. Peripheral eosinophilia, poly or monoclonal hypergammaglobulinemia and increased erythrocyte sedimentation rate can be seen. Clinical features begin acutely, with local edema and a painful and symmetrical stiffening of the limbs, progressing rapidly to fibrosis, which can limit joint movements. Some cases have a history of strenuous physical exercise or trauma. The diagnosis is confirmed by a deep skin biopsy. Glucocorticoids in high doses is the treatment of choice. We report a typical eosinophilic fasciitis case with peripheral eosinophilia and dramatic response to pulse therapy with methylprednisolone.

Nodular fasciitis on the zygomatic region: a rare presentation / Fasciite nodular na regiao zigomatica: uma apresentacao rara

Nodular fasciitis is a benign tumor, resulting from reactive proliferation composed of fibroblastic/myofibroblastic cells. Due to its rapid growth and high cellularity it may be mistaken for sarcoma. Despite the possibility of spontaneous regression, excision is the treatment of choice. A 24-year-old female patient presented with a nodule on the zygomatic region with 3 months of evolution. Excisional biopsy was performed. Histopathological examination associated with immunohistochemical markers HHF35, AML and Ki-67 allowed diagnostic confirmation. The main relevance of the case presented is its rare location, suggesting its inclusion among the differential diagnoses of tumor lesions on the face.

A fasciíte nodular é um tumor benigno, decorrente da proliferação reativa de células fibroblásticas ou miofibroblásticas. Pode ser confundida com os sarcomas, devido a seu rápido crescimento e rica celularidade. Apesar da possibilidade da involução espontânea, a excisão é o tratamento de escolha. É apresentada uma paciente de 24 anos, com um nódulo de 3 meses de evolução na região zigomática. Foi realizada biópsia excisional. O exame histopatológico associado à imuno-histoquímica com os marcadores HHF35, AML e Ki-67 permitiram a confirmação diagnóstica. A principal relevância do caso apresentado é sua rara localização, sugerindo a sua inclusão entre os diagnósticos diferenciais das lesões tumorais na face.
