title: Recurrent acute pancreatitis and persistent hyperamylasemia as a presentation of pancreatic osteoclastic giant cell tumor: an unusual presentation of a rare tumor.
abstract: Giant cell tumors of the pancreas are rare neoplasms divided into three forms: osteoclastic, pleomorphic, and mixed. We report an unusual case of a 62-year-old male presenting with recurrent acute pancreatitis and found to have a mass in the head of the pancreas on routine imaging. Endoscopic retrograde cholangiopancreatography showed a main pancreatic duct stricture, with brush cytology revealing the diagnosis of osteoclastic giant cell tumor of the pancreas. Whipple's procedure was successfully performed for resection of this tumor. and IAP.
