title: Ectopic gastric mucosa in rectum: a rare cause of rectal bleeding in children.
abstract: A 3-year-old boy with rectal bleeding and colicky abdominal pain is described in whom heterotopic gastric mucosa in the rectum was found. Increased uptake of 99mTc-pertechnetate was demonstrated in two sites: rectum and left colon. However, gastric mucosa could be identified by endoscopic and histologic examination in the rectum only. The patient was asymptomatic after the operation and during follow-up, over 14 months.
