Core Tip
Core tip: Hepatocellular adenomas (HCAs) are uncommon liver tumours with 2 major complications: bleeding and malignant transformation; these lesions are classified based on their distinctive genotypes and clinical phenotypes. HCAs in children may be identified in the setting of conditions such as glycogen storage disorder and familial adenomatous polyposis. However, the molecular subtypes do not always correlate with predisposing risk factors and syndromes. Herein, we will discuss the different subtypes of HCA and the clinicopathological characteristics in children.
