A CASE OF CARCINOID TUMOR AT THE ILEOCECAL VALVE

Abstract

A 42-year-old-male came to our hospital with a complaint of anal bleeding. The colonoscopic examination revealed a nodular tumor, measuring to mm in diameter, at the ileocecal valve. Carcinoid tumor was diagnosed by histological examination of biopsy specimen. Then ileocecal resection with regional lymph node dissection was performed. Histological examination of the resected tissue showed that the carcinoid tumor was located mainly in the submucosal layer with the invasion into the muscular layer at the top of the tumor. No definite metastasis was seen in the lymph node or liver. This case was diagnosed as carcinoid tumor of the ileocecal valve. Only five similar cases including our case have been reported in Japan.
