ABSTRACT
Carcinoid is a tumor that primarily affects the intestinal tract, which arises from entero-chromaffin cells. Rectal carcinoid tumor is a relatively rare neoplasm originated in Kul-chitszky cell and clinicians have the difficulties in predicting their malignant potential and in proper treatment. These cells are found to increase in the distal small intestine, are common in the appendix, and then decrease within the mucosa of the colon from cecum to rectum. In the cumulative world literature, the incidence of carcinoids of rectum is slightly higher than 10 percent. All of these tumors are within reach of the rigid procto-sigmoidoscope, most being located between 4 and 13 cm from the anal verge. Eighty five percent are found on the anterior and lateral walls. The tumors are usually submucosal and light yellowish or reddish color. The vast majority of rectal carcinoid tumors are be-nign, which can be treated by local excision safely. Lesions larger than 2 cm and invading the muscular wall of the rectum should be considered malignant, which are treated by more radical surgery such as abdominoperitoneal resection. We experienced a case of rectal carcinoid tumor, which was excised by endoscopic polypectomy, so we present this case with a review of relevant literatures.
