Abstract
BackgroundEctopic pancreas (EP) is defined as pancreatic tissue that lacks anatomical or vascular communication with the normal body of the pancreas. Despite improvements in diagnostic endoscopy and imaging studies, differentiating ectopic pancreatic tissue from gastric submucosal diseases remains a challenge.Case presentationHere, we present a case of a 44-year-old woman with severe epigastric pain. Initially, gastric lymphangioma was highly suspected due to a well-demarcated protruding mass with a large size that occurred in the submucosal layer of the gastric antrum and appeared as a cystic lesion. The final correct diagnosis of gastric EP was made during surgery.ConclusionGastric EP with serous oligocystic adenoma appearing as a giant gastric cyst is extremely rare. The difficulty of making an accurate diagnosis and differential diagnosis is highlighted, which may provide additional clinical experience for the diagnosis of EP with serous oligocystic adenoma in the stomach.
Highlights
Ectopic pancreas (EP) is defined as pancreatic tissue that lacks anatomical or vascular communication with the normal body of the pancreas
Gastric EP with serous oligocystic adenoma appearing as a giant gastric cyst is extremely rare
Ectopic pancreas (EP) refers to healthy pancreatic tissue that lacks anatomical, vascular or neural communication with the normal pancreas; EP was probably first described in the eighteenth century when it was found in an ileal diverticulum [1]
Summary
Gastric EP with serous oligocystic adenoma appearing as a giant gastric cyst is extremely rare.
