[A symptomatic ectopic pancreas in the stomach--a case report].

Ectopic pancreas (heterotopic pancreas) is a congenital anomaly and the most common type of ectopic tissue in the gastrointestinal tract. It is typically located in the stomach, duodenum and jejunum. Ectopic pancreas is usually an asymptomatic and benign lesion, in a majority of cases found incidentally during endoscopy or surgery. Generally appears as submucosal lesion with characteristic central umbilication. Complications of heterotopic pancreas are secondary to pathologic changes occurring in the normal pancreatic tissue or caused by ,,mass effect". Asymptomatic cases of ectopic pancreatic tissue are seldom recognized at a preoperative stage. In this paper we reported a case of symptomatic heterotopic pancreatic tissue in a young man, requiring surgical treatment.
