Pseudomembranous colitis is a serious digestive disease that develops in a context clinical-epidemiological quite predictable and most of the time, fatal. We present the case of a Elderly patient suffering left hip fracture, enters the hospital center and develops infection urinary, receiving broad-spectrum antibiotic therapy. Progressively, complications are installed respiratory, digestive and septic, being operated surgically to correct a clinical picture of intestinal obstruction, performing a sigmoidectomy. The macro and microscopic findings corresponded to a typical pseudomebranous colitis. The patient dies five days after the surgery. The entity is reviewed, with emphasis on the pathological findings, in order to make diagnoses safer and faster in future cases.   DOI 10.25176/RFMH.v18.n4.1739

La Colitis pseudomembranosa es una enfermedad digestiva grave que se desarrolla en un contexto clínico-epidemiológico bastante predecible y la mayoría de las veces, fatal. Presentamos el caso de una paciente anciana que sufre fractura de cadera izquierda, ingresa al centro hospitalario y desarrolla infección urinaria, recibiendo terapia antibiótica de amplio espectro. Progresivamente, se instalan complicaciones respiratorias, digestivas y sépticas, siendo intervenida quirúrgicamente para corregir un cuadro clínico de obstrucción intestinal, realizándosele una sigmoidectomía. Los hallazgos macro y microscópicos correspondieron a una típica Colitis pseudomebranosa. La paciente fallece cinco días después de la cirugía. Se revisa la entidad, con énfasis en los hallazgos patológicos, a efectos de realizar diagnósticos más seguros y rápidos en casos futuros.   DOI 10....

ABSTRACT Introduction: Digestive bleeding can put patients’ lives at risk, even more so when the origin is not located in routine upper and lower endoscopy. The small intestine is the largest portion of the digestive tract and being a source of bleeding means a diagnostic and therapeutic medical challenge. Clinical case: We presented cases of two female patients, 53 and 60 years old, who develop digestive bleeding, locating its origin in the small bowel and undergoing surgical removal of the affected intestinal segment. The anatomopathological study finds malformed arteries and veins that communicate without an intermediate capillary bed. The diagnosis was arteriovenous malformation, a rare entity in the small bowel. Both cases are reviewed with emphasis on the histopathological criteria and their clinical correlation. Keywords: Arteriovenous malformation, small bowel, obscure digestiv...

Juvenile Xanthogranuloma is a non-neoplastic skin lesion of the non-Langerhans histiocytosis type, which mainly affects the pediatric population and usually has a self-limited course. Exceptionally, the lesion is multifocal, ocular and even visceral, causing severe complications. We present the case of two 10-year-old female patients, with no other symptoms or important history, both with a single lesion, one on the thigh, with 3 months of evolution, the other on the scalp, with 4 months of evolution, both with progressive growth and surgically removed. The anatomopathological study identified multiple histiocytes in the dermis, with cytoplasmic lipidization and forming giant multinucleated cells, some of the Touton type, characteristic of this lesion. This unusual entity is reviewed, with emphasis on the histopathological criteria and the usual clinical course.
