Perihilar tumors, also called Klatskin tumors, are the most common cholangiocarcinomas. They occur in the hilum region at the bifurcation of the right and left hepatic ducts. Intrahepatic tumors are the least common. Distal extrahepatic tumors are located in the common bile duct, which inserts into the small intestine. More than 95% of these tumors are ductal adenocarcinomas.
