title: [An anatomicoclinical case of lipoma of the sigmoid].
abstract: The authors describe a case of a submucosal lipoma of the large intestine. Family, physiological, and remote anamnesis of the patient was negative to inflammatory or neoplastic intestinal diseases. The symptomatology was not characteristic like the several cases reported in the literature, by abdominal cramps, subocclusion or total occlusion crisis and rectal bleeding. The patient presented with a symptomatology characterized by altered bowel habit, and evacuations of blood-stained feces. The clinical diagnosis was difficult for the aspecific symptoms referred. A barium enema and colonoscopy examination showed a suspected benign neoformation localized within the sigmoid colon. The patient underwent surgery and the following histologic exam exhibited a submucosal lipoma with an atrophied superficial epithelium replaced by necrotic and granular tissue, marked architectural disarray of glandular crypts and intensive inflammatory infiltrate of tunica mucosa.
