A case of hemorrhagic cyst of the pancreas resembling the cystic endometriosis.
A 47-year-old Japanese woman with a history of epigastric pain and a recent episode of acute pancreatitis (back pain, nausea, and vomiting) and anemia was found to have a pancreatic cyst of the tail on CT-scan and ultrasonography. Especially, ultrasonography revealed the papillary solid lesion in the cyst. With the tentative diagnosis of a cystic neoplasm, distal pancreatectomy was performed. Histological examination of sections showed massive hemorrhage, surrounded fibrous connective tissue, and numerous macrophages with hemosiderin deposits; these histological findings resembled cystic endometriosis. The clinicopathological features and pathogenesis of the pancreatic endometrial cyst are discussed.
