Abstract

Ectopic pancreas is defined as being the presence of pancreatic tissue outside its usual or habitual location and without anatomic relation either of continuity or of vascularization with the pancreatic proper. The most common developing sites are the stomach(especially greater curvature of antrum), duodenum and proximal jejunum. Most lesions do not cause any clinical symptoms, but sometimes nonspecific significant symptoms appear. We report 2 cases of ectopic pancreas located in the pyloric region in a 13 year-old girl and a 12 year-old boy who had symptoms of epigastric pain, nausea, vomiting and dyspepsia. Gastrofiberscopy revealed 2 cm sized submucosal mass with double circular folds and 0.8 cm sized submucosal polypoid mass with central umbilication in the posterior wall of the pyloric region respectively. Wedge resections were performed, although the 12 year-old boy required a second operation due to pyloric obstruction. Histologic findings showed pancreatic acini and Langerhan`s islet within gastric submucosa and muscle layer, and pancreatic acini and duct within gastric submucosa layer respectively. Symptoms disappeared after complete removal of the ectopic pancreas by operation.
