A Case of Carcinoid Tumor of the Rectum / 대한소화기내시경학회지

Carcinoid tumor primarily affects the intestinal tract, which arise from the Kulchitsky cells found at the base of the crypts of Lieberk hn. Rectal carcinoids are relatively uncommon lesions, representing only 1.3 percent of all rectal tumors. Rectal carcinoids have benign course and are usually asymptomatic. While their prognosis is generally favorable, it is known that about 15% of these tumors metastasize. Rectal carcinoid tumors should be treated appropriately and aggressively when indicated. Present-day treatment programs call for radical cancer resection only for lesions larger than 2 cm in diameter and local resection for all others. We have experienced a case of carcinoid tumor of the rectum treated by endoscopic polypectomy.
