Epithelioid XXXX of the colon: a case report.

@entity1712 @entity1 @entity2695 @entity5 @entity5072 @entity1350 @entity490 @entity14 @entity2280
CONTEXT: Epithelioid @entity2695 or @entity5072 with @entity1712 is an uncommon @entity1350 that is usually located on the face or neck. Exceptionally, it has been described affecting the colon, with only two such cases described in the worldwide literature. The aim here was to present a case of primary @entity2695 of the sigmoid colon with confirmation by immunohistochemical examination. CASE REPORT: A 37-year-old @entity1 had had a complaint of intermittent @entity490 for six months. Two months after the condition started, she began to present changes in her intestinal habit, with evacuations containing blood and mucus and a weight loss of 4 kg over this period. At physical examination, a palpable mass was noted in the lower left quadrant of the abdomen. @entity5 of the colon was clinically suspected and she underwent colonoscopy. This demonstrated the presence of a vegetating sessile lesion of approximately 5 cm in diameter, at a distance of 36 cm from the anal margin. It occupied 80% of the intestinal lumen. A biopsy collected during the examination suggested a diagnosis of @entity5 of vascular origin. After surgical resection, histopathological examination of the resected specimen confirmed the diagnosis of @entity2695 of the colon, which was backed up by the immunohistochemical panel (factor VIII, Ki-67, @entity2280 ). At present, three years after the surgery, the @entity1 is asymptomatic, she has recovered her normal weight and she has normal findings from control colonoscopy. Despite the rarity of @entity5 of vascular origin, this possibility should be considered in the differential diagnosis for @entity14 .
