ECTOPIC PANCREATIC TISSUE IN THE STOMACH: CASE REPORT

Abstract

Introduction: Etopic pancreas is a rare developmental anomaly. It is presence of pancreatic tissue without anatomic or vascular continuity with the normally developed pancreas. The most common heterotopic site is the stomach commonly involving antrum and prepyloric region on the greater curvature or posterior wall. Ectopic pancreas is diagnosed by endoscopic ultrasound, gastroscopy and biopsy, CT scan and MRI of the abdomen, a definitive diagnosis is verified by histopathological examination. Treatment is surgical. Case report: A 56-year-old woman presented with epigastric pain, nausea and fatigue. Esophagogastroduodenoscopy showed submucosal mass in the prepyloric region, biopsy was performed. Histopatological findings described normal gastric mucosa. Endoscopic ultrasonogpraphy and CT of the abdomen showed submucosal tumor, 18 mm in diameter, located in the prepyloric region. Surgical treatment was indicated. Gastrotomy with total extraction of tumor was performed. Histopathology findings showed ectopic pancreatic tissue in the submucosal and muscular layer of the stomach. Postoperatively patient fully recovered, and in the 2 year folow-up did not develop any symptoms related to gastrointestinal tract. Conclusion: Although presentation of ectopic pancreatic tissue in stomach is very rare condition, it should be considered during gastroitestinal diagnostic in patients with nonspecific gastrointestinal symptomatology. In most of cases, for this patients, surgery is curative and definitive solution.
