AOASE OF CARCINOID TUMOR IN THE TERMINAL ILEUM DIAGNOSED PREOPERATIVELY

Abstract

A 72-year-old man visited our clinic with a chief complaint of bloody stool. Colonoscopic examination revealed a lesion resembling a submucosal tumor, 5mm in diameter, inthe terarninal ileum. A histological diagnosis of carcinoid was made based on a biopsyspecimen taken from the lesion. Endoscopic ultrasonography showed the lesion invadingdeeply in the submucpsal layer. Having cpnsidered the depth and lpcation of the carcinid tuner, ileeceeal resectien was performed. Only 7 cases of carcineid turners in the terminalileum diagnosed before operation have been reported in Japan. Our case is the smallest oneof the 7 cases.
