Overview
Classification
Cholangiocarcinoma may be classified according to location of the tumor into 3 subtypes:[1]
- Extrahepatic bile duct cancer
- Perihilar bile duct cancer
- Intrahepatic bile duct cancer
Cellular Classification of Cholangiocarcinoma
Extrahepatic Bile Duct Cancer
- Carcinoma in situ
- Adenocarcinoma, not otherwise specified (NOS)
- Adenocarcinoma
- Intestinal type
- Mucinous type
- Clear cell type
- Signet-ring cell carcinoma
- Adenosquamous carcinoma
- Squamous cell carcinoma
- Small cell (oat cell) carcinoma
- Undifferentiated carcinoma
- Spindle cell type
- Giant cell type
- Small cell type
- Papillomatosis
- Papillary carcinoma
- Noninvasive
- Papillary carcinoma
- Invasive
- Carcinoma, NOS
Perihilar Bile Duct Cancer The histologic types include the following:
- Carcinoma in situ
- Adenocarcinoma, not otherwise specified (NOS)
- Adenocarcinoma:*Intestinal type
- Mucinous type
- Clear cell type
- Signet-ring cell carcinoma
- Adenosquamous carcinoma
- Squamous cell carcinoma
- Small cell (oat cell) carcinoma
- Undifferentiated carcinoma
- Spindle cell type:*Giant cell type
- Small cell type
- Papillomatosis
- Papillary carcinoma:*Noninvasive
- Papillary carcinoma*:Invasive
- Carcinoma, NOS
Intrahepatic Bile Duct Cancer
- Mass-forming tumor growth pattern
- Periductal-infiltrating tumor growth pattern
- Mixed mass-forming and periductal-infiltrating growth pattern
