A case of symptomatic heterotopic pancreas with huge pseudocyst formation / 대한내과학회지

ABSTRACT

Heterotopic pancreas is the presence of pancreatic tissue that lacks anatomic and vascular continuity with the main body of the pancreas. Most patients with heterotopic pancreas are asymptomatic. Any pathologic change in the normal pancreas also can occur in heterotopic pancreas; namely, pancreatitis, cyst formation, hemorrhage, necrosis and neoplastic chang. But pancreatic pseudocyst formation is extremely rare in heterotopic pancreas. Recently, we experienced a case of gastric heterotopic pancreas in a 22-year-old women complicated by chronic pancreatitis with pseudocyst formation. She underwent a antrectomy with Billroth I reconstruction. Symptoms were relieved after operation. Microscopic findings were compatible with gastric heterotopic pancreas with pseudocyst formation. Herein, we report a case of symptomatic heterotopic pancreas with huge pseudocyst formation and the pertinent literatures were reviewed briefly.
