A Case of Carcinoid Tumor at the Ileocecal Valve

Abstract

A 58-year-male came to our hospital with a complaint of lower abdominal pain. The barium enema examination showed a protruding lesion at the ileocecum. The colonoscopic examination revealed a nodular tumor with ulceration, measuring 15×10 mm in size, at the ileocecal valve. The result of the biopsy showed carcinoid tumor. No metastatic lesion was detected by the CT scan and the Ga scintigram. No specific result was found on the hormonal study. Then a right hemicolectomy was performed.
This case was diagnosed as carcinoid tumor of the iliocecal valve. Only four similar cases have been reported in Japan.
