Pancreatic endometrial cyst: Report of a case


A pancreatic endometrial cyst is an extremely rare disease. Since 1984, only 7 cases have been reported, including the current case. A 35-year-old woman with a history of recurrent severe left upper abdominal pain of 3 months’ duration was found to have a cyst in the pancreatic body on the diagnostic imaging findings. With a preoperative diagnosis of mucous cystic adenoma, she underwent a distal pancreatectomy. The histopathological examination of the specimen revealed a pancreatic endometrial cyst. She complained about severe periodic abdominal pain during the convalescence, without any surgical complications. This study reviews previous reports of pancreatic endometrial cysts, and also discusses the clinicopathological features, pathogenesis, and appropriate treatment for this disease.
