摘要
Hepatocellular adenoma(HCA)is a benign hepatocellular neoplasm,commonly occurs in young women with a history of oral contraceptive use.Complications including hemorrhage and malignant transformation necessitate the need for a thorough understanding of the underlying molecular signatures in this entity.Recent molecular studies have significantly expanded our knowledge of HCAs.The well-developed phenotype-genotype classification system improves clinical management through identifying“high risk”subtype of HCAs.In this article,we attempt to provide updated information on clinical,pathologic and molecular features of each subtype of HCAs.
