Esophageal polyps are rare in children, whereas colorectal juvenile polyps are common. An 11-year-old boy with an esophageal colonic interposition for an esophageal stricture secondary to caustic injury was found to have a polypoid mass in the interposed colon. Fiberoptic endoscopic removal with diathermy was performed. Histological examination confirmed it was a juvenile polyp. The occurrence of a polyp in a colon removed from its natural location and serving a different function suggests the possibility that an unknown factor produced by colonic cells play a pivotal role in its development.
