Pseudocyst formation in gastric ectopic pancreas

Abstract

Context: It is rare for ectopic pancreatic tissue to cause symptoms or require treatment, however diseases of normal pancreas may also occur in ectopic pancreas tissue.

Case report: This report describes the clinical, endoscopic, radiologic and histologic features of a pseudocyst occurring in gastric ectopic pancreas in a 19-year-old man. The difficulty and implications of making an accurate pre-operative diagnosis are highlighted.

Conclusion: Ectopic pancreatic tissue, although rare, should be considered in the differential diagnosis of a submucosal gastric mass.
