A strong relationship exists between cholangiocarcinoma and primary sclerosing cholangitis. Cholangiocarcinoma generally develops in patients with long-standing ulcerative colitis and primary sclerosing cholangitis.

At increased risk are patients with ulcerative colitis without symptomatic primary sclerosing cholangitis and a small subset of patients with Crohn disease.
