Mucus producing cholangiocarcinoma secrets large amount of mucus and is often difficult to make diagnosis accompanied with varieties of symptoms and pictures in image studies. We report a case of mucus producing cholangiocarcinoma in which PTCS was useful in making diagnosis and selecting the choice of surgical treatment. The patient was 78-year-old female who presented to us with general malaise, anorexia and fever. The blood test revealed the presence of mild inflammation, mild elevation of hepatic enzymes and CEA. The intrahepatic and common bile ducts revealed significant dilatation in US and CT studies and abnormal images in ERCP. The study with PTCS revealed mucoid and granular disease in the intrahepatic ducts of posterior segment and common bile duct. Accordingly, the diagnosis of mucus producing cholangiocarcinoma was strongly suspected and resection of posterior hepatic segment, extrahepatic bile duct and removal of D2 lymphnodes were performed on Dec. 10th, 2001. The pathological diagnosis was well differentiated adenocarcinoma arising in papillomatosis. The patient is surviving without sign of recurrence three years after the operation.
