According to their localization, cholangiocarcinomas (CCAs) are classified into intand extrahepatic forms.
Eighty to 90% of the tumors are extrahepatic.
The extrahepatic forms include perihilar tumors known as Klatskin tumors, which are located at the junction of the right and left hepatic forming the common hepatic duct, and distal bile duct tumors.
Most extrahepatic CCAs appear as firm, gray nodules within the bile duct wall
Klatskin tumors generally have slower growth than other CCAs, show prominent fibrosis, and infrequently involve distal metastases.
