title: [Ganglioneuromatosis with carcinoid foci in the large bowel].
abstract: A rare case of a 27-year-old man who suffered from ganglioneuromatosis with five carcinoid foci arising from the colon and underwent subtotal colectomy is reported. There was no malignancy. The tumors extended to the mucosa and/or submucosa, and in most parts, tumors created polypoid lesions protruding into the intestinal lumen. In the rectum the tumors showed circumscribed extension around the wall. In the sigmoid and descending colon, polypoid lesions were seen on the side opposite from the attachment line of the mesocolon. In one of five carcinoid foci, a transitional pattern between carcinoid and neuroma was investigated.
