A 56-year-old female visited our hospital with positive indication of fecal occult blood. Endoscopy revealed a submucosal tumor, 10mm in diameter, in the lower rectum. Endoscopic ultrasonograpy revealed a low echoic lesion between the second and third layer, and strong echo area in the center of the lesion. We performed endoscopic mucosal resection for this lesion. Histrogical diagnosis was rectal carcinoid, and carcification was found in the center of the tumor. A case of gastrointestinal carcinoid with carcification is rare. We discussed and reported about rectal carcinoid with carcification.
