Core Tip

Core tip: This review article focuses on the current views about the histopathology and clinical characteristics of combined hepatocellular cholangiocarcinoma (CHC). Whether the different components of CHC share a common cell origin is still ambiguous. Furthermore, the definition of CHC subtype is still ambiguous and the identification of CHC subtype when a single tumor contains many components has remained unresolved. The features between hepatocellular carcinoma (HCC) and cholangiocarcinoma (CC) make CHC has better prognosis than CC but poorer than HCC.
