[Submucosal gastric tumour: heterotopic pancreas. A case report and review of the literature].

Heterotopic pancreas is the presence of pancreatic tissue outside the anatomical location of the pancreas. It is a rare condition and can occur anywhere in the gastrointestinal tract with the stomach and small bowel as the most common sites. It is usually asymptomatic but may become clinically evident when complicates by pathologic changes such as inflammation, bleeding, obstruction and malignant transformation. We report the case of a 49-year-old man who presented with recurrent epigastric pain. The upper gastrointestinal endoscopy revealed a submucosal tumour in the antrum. The histopathology study after surgery showed a heterotopic pancreatic tissue. Ectopic pancreas should be considered in the differential diagnosis of a submucosal gastric tumour.
