Two patients with a sclerosing type of cholangiocarcinoma are reported. One, a 68‐year‐old male, presented with jaundice and mild right upper abdominal pain. Endoscopic retrograde cholangiography showed diffuse narrowing and irregularity of the intra‐ and extrahepatic bile ducts, suggestive of primary sclerosing cholangitis. The other patient was a 72‐year‐old female who complained of slight right upper abdominal pain, lassitude, and anorexia. Both ultrasonography and computed axial tomography demonstrated slight dilatation of the anterior branch of the right hepatic duct, but no mass. Endoscopic cholangiography revealed stenosis of that duct and diffuse irregularity of the other intrahepatic ducts, also suggestive of primary sclerosing cholangitis. In both patients, however, transpapillary cytology of bile demonstrated malignant cells, and biopsy from within the bile duct showed cholangiocarcinoma. Both transpapillary cytology and biopsy, especially the latter, are useful procedures for the diagnosis of this unique clinical entity.
