AB  - We report a rare case of heterotopic gastric mucosa presenting in a jejunal polyp of a 9-year-old girl, diagnosed with capsule endoscopy and laparoscopic exploration, after a 15-month history of lower gastrointestinal bleeding and anaemia. During surgery, the jejunal segment containing the polyp was resected and pathological examination revealed a polyp with gastric heterotopia. Heterotopic gastric mucosa is a rare pathology characterised by the presence of gastric mucosa outside of the stomach. Heterotopic gastric mucosa usually occurs in the oesophagus, duodenum, Meckel's diverticulum and enteric duplication cysts. It can be either congenital (heterotopic) or acquired (metaplastic). Symptoms vary from mild dyspepsia to massive gastrointestinal bleeding.
