Early gallbladder carcinoma associated with primary sclerosing cholangitis and ulcerative colitis.
Patients troubled with primary sclerosing cholangitis (PSC) and ulcerative colitis (UC) are at high risk for cholangiocarcinoma, whereas cancer of the gallbladder (GBC) is rarely reported to develop in that population. A Japanese man aged 62 years with a 14-year history of PSC and UC had been found to have a protruding lesion of the gallbladder by screening sonography. The preoperative examination suggested the lesion to be GBC at an early stage. Pathology examination after cholecystectomy proved that the lesion was papillary adenocarcinoma localized in the mucosal layer. Although the prognosis of GBC is poor, the outcome of cholecystectomy against early GBC is relatively good. Early detection of the tumor is required for a better prognosis of patients with GBC. According to the review of the literature, PSC and UC patients are regarded as a high-risk group not only for cholangiocarcinoma but also GBC. It is advocated that clinicians perform repeated radiographic examinations including sonography for patients with PSC and UC even if the diseases are being controlled.
