Congenital hemangioma（CH）is a relatively rare benign vascular tumor that is present before birth．Based on the growth characteristics of CH after birth，CH can be classified into four types：non-involuting congenital hemangioma，partially involuting congenital hemangioma，rapidly involuting congenital hemangioma，and delayed expanding congenital hemangioma．Different types of CH exhibit distinct clinical features and require different treatment approaches．This review focuses on recent research advances in CH，including its pathogenesis，clinical characteristics，diagnosis，and treatment，aiming to provide better guidance for clinical practice．
