Cholangiocarcinoma: clinical manifestations and diagnosis

Cholangiocarcinoma (CCA) is the most common malignancy of the biliary tract. CCA most commonly presents with perihilar tumor location, the so-called “Klatskin tumor”. However, mass-forming CCAs can also occur. The most important mimicker of CCA is IgG4-associated cholangiopathy, which can create strictures radiologically resembling CCA. Chronic inflammatory processes in the liver and biliary tree may be involved in biliary carcinogenesis. Li ver fluke infestation and Oriental cholangiohepatitis are seen primarily in Asia, and increase the risk of CCA.
