title: Carcinoma of the biliary tree complicating Crohn's disease.
abstract: A patient with long-standing Crohn's disease who subsequently developed carcinoma of the biliary tree is described. Biliary tract neoplasia may represent another extraintestinal complication of Crohn's disease, but its frequency of association is probably less than that of ulcerative colitis.
