Liver and intrahepatic bile ducts
Hepatocellular adenoma (HCA) is a benign liver neoplasm composed of neoplastic hepatocytes. The incidence is about 3–4 per 100 000 population in Europe and North America

but lower in Asia. Eighty-five percent of cases occur in young women. The major risk factor for HCA is exposure to estrogenic or androgenic steroids; in young women with HCA, 80% have been users of oral contraceptives and risk increases with duration of use. Nonhormonal risk factors include glycogenosis type 1 (von Gierke disease) or 3 (Forbes disease), galactosaemia, tyrosinaemia, familial polyposis coli, and hepatic iron overload with β-thalassemia

. HCAs are classified into four different subtypes: (1) HNF1α-inactivated HCA, (2) β-Catenin-activated HCA, (3) inflammatory HCA and (4) unclassified HCA, which vary greatly in their clinical, pathological, and radiological features
