The hepatocellular adenomas are classified on the basis of molecular patterns called phenotypic-genotypic classification into 4 major groups, including HNF1-alpha inactivated adenoma, beta-catenin activated adenoma, inflammatory hepatic adenoma and unclassified type adenoma.


Hepatocellular Adenoma
HNF-1 alpha inactivated adenoma
Beta catenin activated adenoma
Inflammatory hepatic adenoma
Unclassified type adenoma

HNF-1 Alpha Inactivated Hepatocellular Adenoma (35 - 40%)

Inflammatory Hepatocellular Adenoma (40 - 50%)

Beta-catenin Mutated Hepatocellular Adenoma (10 - 15%)

Unclassified Hepatocellular Adenoma (10%)
