[Pancreatic heterotopia as a rare diagnosis of a size increasing gastric tumor].
A 39 years old woman was noted to have a submucosal gastric tumor during gastroscopy for cholecystectomy. She was asymptomatic regarding this tumor. The patient was primarily observed, but the tumor size increased. The lesion was biopsied with a negative result. A local excision with simultaneous endoscopy was done laparoscopically. Malignancy was excluded by immediate sectioning. Histological examination revealed pancreatic heterotopy Type I by Heinrichs- with exocrine and endocrine cells. The patient had an uneventful postoperative course. Eight months after resection the patient was free from recurrence and symptoms.
