This patient was a 60-year-old man. He had no complaint and no drinking history. Dilatated pancreatic duct was detected at the annual medical check up on March 2000. Endoscopic retrograde pancreatography revealed localized narrowing of the main pancreatic duct in the pancreatic body. The result of pancreatic juice cytology showed no malignancy. Endoscopic ultrasonography and intraductal ultrasonography revealed a mass-forming lesion around the narrowed pancreatic duct. He underwent segmental resection of the pancreatic body, because we suspected small pancreatic cancer. Microscopic examination showed carcinoma in situ on the narrowed pancreatic duct and thick fibrosis around the pancreatic duct. The mechanism of the fibrosis is unknown, however, it might be related to carcinoma in situ. We have to consider carcinoma in situ of the pancreas for localized narrowing of the pancreatic duct.
