Abstract

• The most common malignant hepatic tumor is by far hepatocellular carcinoma, followed by intrahepatic cholangiocarcinoma. However, other primary malignancies can occur and require specific approaches.

• Cystadenocarcinoma is a cystic tumor that usually develops from hepatic biliary cystadenoma. In both cases, radical surgical resection is the treatment of choice.

• Primary hepatic lymphomas are very rare (contrary to the frequent secondary involvement of the liver in disseminated non-Hodgkin lymphoma) and frequently associated with hepatitis C virus infection. Chemotherapy is efficient for most tumors and surgical resection indicated for complete resection of limited tumors or to reduce tumor burden before systemic therapy.

• Most cases of hepatoblastoma occur in childhood. Prognosis in adults is much poorer due to late diagnosis. Treatment is based on complete surgical resection.

• Hepatic epithelioid hemangioendothelioma is a rare vascular tumor with variable degrees of aggressiveness. Surgical resection (including liver transplantation) is the best approach when no extrahepatic involvement is present.

• Angiosarcoma, the most common primary hepatic sarcoma, represents up to 2%of primary liver malignancies, occurs more frequently in aged patients, and carries a very poor prognosis. Surgical resection is the best option in resectable cases, although recurrence is very common. Chemotherapy and trans-arterial therapy are used alone (to prevent bleeding and avoid tumor growth) or in combination with surgery.
