先天性血管瘤（CH）是一种较为罕见的良性血管肿瘤，出生前瘤体已经存在，按照出生后瘤体的生长特征可分为4类：不消退型CH、部分消退型CH、快速消退型CH以及迟发性扩张型CH。不同类型的CH其临床特征及治疗方式不同。结合近年CH的研究进展报道，文章对CH的发病机制、临床特征、诊断及治疗着重进行综述，以期更好地为临床诊治提供指导。

        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．
