LOPEZ PANQUEVA, Rocío del Pilar. Malignant Hepatic Neoplasms. Part 2. Morphology and important ancillary studies useful for histopathological diagnosis. Rev Col Gastroenterol [online]. 2015, vol.30, n.3, pp.361-372. ISSN 0120-9957.

We continue with the review of primary malignant liver tumors. This article covers the most important aspects of primary tumors that are not hepatocellular. Those that originate in the epithelium of the bile duct such as cholangiocarcinoma, cystadenocarcinoma and mesenchymal tumors occur most frequently. Epithelioid hemangioendothelioma and angiosarcoma occur less frequently. The main difficulty lies in making a definitive diagnosis which must be based on the exclusion of extrahepatic primary neoplasms and benign liver lesions. Additional immunohistochemistry and molecular studies as well as diagnostic cloning of cells can be very useful

Keywords : Malignant liver tumors; cholangiocarcinoma; cystadenocarcinoma; epithelioid hemangioendothelioma; angiosarcoma; immunohistochemistry.
