NCI Definition: A benign or malignant neoplasm that affects the intrahepatic or extrahepatic bile ducts. Representative examples of benign neoplasms include bile duct adenoma and extrahepatic bile duct lipoma. Representative examples of malignant neoplasms include intrahepatic and extrahepatic cholangiocarcinoma. [1]

Bile duct neoplasms most frequently harbor alterations in TP53, KRAS, IDH1, ARID1A, and CDKN2A [2].

Most Commonly Altered Genes in Bile Duct Neoplasm

TP53 Mutation, KRAS Mutation, TP53 c.217-c.1178 Missense, TP53 Missense, and KRAS Exon 2 Mutation are the most common alterations in bile duct neoplasm [2].
