A CASE OF ABERRANT PANCREAS WITH CYST FORMATION

Abstract

A 50-year-old woman was admitted to our hospital with a complaint of epigastralgia, who had an episode of a submucosal tumor in the gastric antrum detected by an endoscopyfive years ago. An endoscopy on admission revealed that the tumor had increased in size And the tumor was considered to have a cystic lesion on an ultrasonography and computed tomography. A wedge resection of the turnor was performed following a biopsy and a puncture which could show no particular findings on pathological study. On the macroscopic examination of the resected specimen, the tumor consisted of a yellow nodule 5mm in diameter and cystic components. The cyst was found to contain macinous fluid. The pathologic diagnosis was a gastric antral aberrant pancreas with a cyst formatiorn, which involved pancreatic acinar cells, ducts and a few numbers of islands of Langerhans. There are few reports that the aberrant pancreas associated with cystic lesion and that EUS studies were done in such cases. We report our case of the aberrant pancreas withacystic formation that was pointed out by EUS and reported cases in Japan.
