Abstract

Ectopic pancreas is an uncommon clinical finding, and it is rare for heterotopic pancreatic tissue to cause symptoms. The most common sites for ectopic pancreas are the submucosal layer of the stomach and the small intestine. An ectopic pancreas is subject to various pathological changes occurring in the pancreas itself, namely cyst, pancreatitis, hemorrhage, abscess, necrosis, and neoplastic changes. We report a case of a gastric ectopic pancreas associated with elevated serum carbohydrate antigen 19-9 (CA 19-9). We performed endoscopic submucosal dissection for histologic diagnosis and removal of the submucosal tumor in the stomach, and histological examination confirmed ectopic pancreas tissue. One months later, serum CA 19-9 declined to a normal level.
