Abstract
IntroductionGastric heterotopic pancreas (HP) is usually asymptomatic and benign; however, it may become evident when it is complicated by pathological changes such as inflammation, bleeding, and malignant transformation. Presentation of caseA 43-year old man was diagnosed with gastric HP 18 years prior suffered a haemorrhage from the enlarged gastric HP with multiple cystic lesions. Although endoscopic ultrasonography–guided fine needle aspiration showed no malignancy, he underwent a partial gastrectomy for diagnosis and treatment. Postoperative histological findings revealed ectopic pancreatic tissue with retained cysts that consisted of dilated pancreatic ducts without malignancy. DiscussionThis is a first report of enlarged gastric HP due to the expansion of retained cysts. Gastric HP is rarely enlarged by pathological changes including inflammation, retention cysts, or malignant neoplasms. ConclusionSymptomatic enlarged gastric HP should be respected and further examined histologically to ensure diagnostic accuracy.
