LONG-TERM FOLLOW-UP CASES OF THE MUCIN PRODUCING PANCREATIC TUMORS: REPORT OF TWO CASES WITH SPECIAL PEFERENCE TO THE CHANGES OF PANCREATOGRAM

Abstract

Two cases of mucin producing pancreatic tumors, followed for four years, were experienced. The first case was a 68-year old female and was initially diagnosed as having the chronic pancreatitis with local dilatation of the main pancreatic duct in the tail of the pancreas. ERP done 4 years later demonstrated marked diffuse dilatation of the main pancreatic duct and findings of papilla of Vater showed characteristically the mucin producing pancreatic tumors. Surgical management was performed and the tumor was histopathologically papillary adenoma. The second case was a 87-year old female with cystic lesion in the body of the pancreas. Findings demonstrated by CT and pancreatogram by ERP showed no marked interval change after 4 years. The tumor was histopathologically the intraductal papillary adenocarcinoma. Findings of the pancreatic duct and papilla of Vater seemed to be mainly affected by the amount of mucin from the tumor. There was no relation of degrees of histopathological malignancy. Local dilatation of the main pancreatic duct supposed to be an inital change of the mucin producing pancreatic tumor in association with a development of diffuse dilatation of the main pancreatic duct.
