According to their anatomical origin in the biliary tract, cholangiocarcinomas can be subdivided into three distinct categories, namely intrahepatic, perihilar, and distal cholangiocarcinoma. Besides definitional purposes, considering each category of different biologic characteristics and clinical course, such a classification is useful in diagnostic approach and clinical management.
