Four @entity1 had resection for primary @entity99 : one with @entity1418 ( @entity1418 ), two with poorly differentiated @entity1492 , and one with @entity1822 . Age ranged from 40 to 69 years. One @entity1 had a cousin and a grandmother who had died of @entity99 . At presentation, all @entity1 had @entity158 ; one had @entity5 rupture, and one had mental changes and @entity4053 . None had @entity99 or @entity82 . Results of laboratory evaluation were nonspecific, including normal carcinoembryonic antigen and @entity160 levels. Computed tomography showed hypodense masses with enhancement. Angiography showed a hypervascular mass in three @entity1 and an avascular mass in the @entity1 with @entity1418 . Despite large @entity5 (8 to 32 cm), portal and hepatic veins were not invaded. The pattern of vascularization and lack of venous invasion helps differentiate primary @entity99 from @entity157 , especially in noncirrhotic @entity1 . All @entity1 had extensive hepatic resections, with one @entity204 . Immunohistochemical stains of the @entity5 were positive for vimentin but negative for epithelial markers, differentiating these lesions from other @entity99 . The @entity1 with @entity1418 died with recurrence at 10 1/2 months. The @entity1 with the @entity397 had a second resection and chemotherapy, but died with recurrence at 3 years. The @entity1 with the @entity1822 had a second resection and was disease free at 4 years. Resection of primary @entity99 is warranted, with potential survival measured in years.
