title: Advanced cholangiocarcinoma in a patient with stage I primary sclerosing cholangitis.
abstract: A 29-year-old woman presented with jaundice and fever in May 2001. Cholangiography showed multiple strictures and beading of the biliary tree, with a large stricture in the common bile duct and marked dilatation of the hilar bile ducts. Typical cholangiography findings and elevated hepatobiliary enzymes suggested primary sclerosing cholangitis (PSC). At the same time, computed tomography detected a 2-cm tumor in the common bile duct, and angiography showed an encasement in the portal vein. Tumor markers, cytology, and biopsy were all negative for cancer. Although laparotomy showed a healthy liver and no lymph node metastasis was found, suggesting early-stage PSC and a low likelihood of accompanying cholangiocarcinoma (CCA) reported so far, the tumor in the resected common bile duct was subsequently diagnosed as CCA. Therefore, pancreatoduodenectomy was performed combined with partial resection of the portal trunk. Histology also revealed invasion of the wall of the portal vein by cancer cells. The patient had a recurrence 5 months later and died 12 months after her operation. This is a rare case in which stage I PSC was complicated by advanced CCA.
