Cholangiocarcinoma is the most common primary malignancy of the biliary tract. Currently, this cancer is classified into the following types according to its anatomic location along the biliary tree: intrahepatic, perihilar or distal extrahepatic. These cholangiocarcinoma types differ in their biological behavior and management. Blechacz et al. discuss the emerging diagnostic criteria as well as the different staging systems for cholangiocarcinoma, and provide a critical appraisal regarding these advances in biliary tract malignancies.
