Cholangiocarcinoma and Crohn's disease

Cholangiocarcinoma is an infrequent complication of inflammatory bowel disease. Although increasing numbers of cholangiocarcinomas are being reported in association with ulcerative colitis, the occurrence of this disease in patients with Crohn's disease is rare. To understand this complication better, we have reported the case of a patient with Crohn's disease in whom cholangiocarcinoma subsequently developed and reviewed the literature.
