Pseudocyst formation in gastric ectopic pancreas.
BACKGROUND
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.


METHODS
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.


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