Rectal carcinoid tumors are relatively uncommon and make up 1∼2% of tumors found in the rectum. Approximately 50% of the tumors are asymptomatic and are found incidentally. In most cases, the tumors are slowly growing in nature and thus have a favorable outcome. Anywhere from 66 to 80% of rectal carcinoid tumors are smaller than 1 cm and rarely metastasis. However, malignant behavior, such as invasion to the muscle wall, and metastasis to a distant organ, may be seen infrequently with tumors greater than 2 cm in size. The liver is the most common site of a metastasis. We experienced a case of a 1 cm sized small rectal carcinoid tumor with multiple liver metastases. (Korean J Gastrointest Endosc 2007;34:233⁣238)
