A 59-year-old man with mucin-producing pancreatic tumor is reported. In January 1973, he was first seen at this hospital because of occasional episodes of abdominal pain after drinking large amounts of alcohol, and a diagnosis of chronic pancreatitis was made. At that time ERCP findings showed a small pancreatic cyst at pancreatic body and a minute radiolucency in main pancreatic duct near the cyst. The second ERCP examination performed in June 1980 showed a dilatation of main pancreatic duct with amorphous filling defects at the body of pancreas, which was thought to be protein plugs. The third ERCP examination performed in November 1985 revealed a large cystic lesion at the pancreatic body and a remarkable dilatation of proximal main pancreatic duct with irregular filling defects. Endoscopic findings at the ERCP showed widely enlarged orifices of both major and minor papilla with retention of mucous material. Those characteristic findings led to the diagnosis of mucin-producing pancreatic tumor. The distal pancreatectomy was performed in May 1986. Histopathological examination revealed a papillaly adenoma with a size of 1.5×1cm in the cystic dilated main pancreatic duct.
