Heterotopic gastric mucosa (HGM) is a rare entity that can occur anywhere in the gastrointestinal tract; its exact genesis remains unclear. While HGM is usually asymptomatic, it can occasionally cause bleeding, obstruction and perforation.

A 31-year-old woman presented with episodic cramping abdominal pain. A small bowel capsule endoscopy revealed a large lesion within the proximal small bowel. During anterograde double-balloon enteroscopy a 60mm sessile polypoid lesion was identified, at the jejunum.

Wide-field endoscopic-mucosal-resection was performed. Histology revealed gastric-type mucosa with mixed mucinous and specialised glands. Reactive changes with foveolar-hyperplasia and reactive nuclear features were seen and HGM diagnosis was made.
