Abstract
Carcinoid tumors of the rectum are relatively uncommon and comprise only about one percent of all rectal neoplasms. Typically, rectal carcinoids present as small, solitary submucosal nodules and have benign course. But, multicentricity is rare. The frequency of an associated second malignancy is about 13%. The explanation of the high frequency of other neoplasms associated with carcinoid tumors is still unclear. We have experienced two cases of multiple carcinoid tumors of the rectum, one was coexisted with adenocarcinoma of the sigmoid colon. They presented with mass on the right inguinal area and hematochezia. Carcnoids was found incidentally. Because the tumors measured 15 mm or less in diameter, did not infiltrate beyond the submucosal layer and had no histological atypia, carcinoids was treated by endoscopic polypectomy and mucosal resection. Thereafter, one underwent surgery for adenocarcinoma of the sigmoid colon. Herein we present our experience with reviewed literatures. (Korean J Gastrointest Endosc 2001;23:192-196)
