Abstract
Carcinoid tumors are enigmatic slow growing malignancies which occur most frequently (74%) in the gastrointestinal tract. Rectal carcinoids comprise 12.6% of all carcinoid tumors and represent the third largest group of the gut carcinoids. The initial symptoms of carcinoid may be nonspecific when present and symptoms are dependent on the location and extent of the tumor. The majority of patients with rectal carcinoid tumors are asymptomatic; and the tumor is after diagnosed incidentally at endoscopy; surgery; or autopsy. Rectal carcinoid tumors are generally small and rarely metastatic and it is known that about 15% of these tumors frequently metastasize to distant organs (especially; liver) when its size is larger than 2 cm. Endoscopic resection may be the best treatment for small tumors. Recently; we experienced two cases of rectal carcinoid tumors which were treated by endoscopic polypectomy; therefore; the cases are presented in this paper with a relevant literature review.
Key Words: Rectal carcinoid tumor, Endoscopic polypectomy
