Colorectal polyps are classified histologically as either neoplastic or nonneoplastic polyps. A juvenile polyp, which is sometimes referred to as a retention polyp, is a type of nonneoplastic polyp. Juvenile polyps are found most commonly in children less than 10 years of age. However, they are also encountered, albeit rarely, in adolescents or adults of all ages. The most common clinical problem is painless rectal bleeding. Most juvenile polyps are found in the rectosigmoid colon, and more than 90% are detected within 20 cm from the anal verge. In Korea, there are some reports of juvenile polyps located in the rectosigmoid colon in adults. We report two cases of juvenile colon polyps in adult that presented as a hematochezia, which were located at the hepatic flexure and ascending colon. (Korean J Gastrointest Endosc 2006;33:372⁣376)
