根据脉管性疾病的细胞生物学特点,Mulliken和Glowacki[1]于1982年提出将其明确区分为血管瘤和脉管畸形两大类。1996年国际血管异常研究协会(ISSVA)在此基础上制定了新的血管病变分类标准[2]。因此血管瘤是一种以血管内皮细胞增生为特征的先天性良性肿瘤,表现为出生即有或出生不久出现的鲜红色斑片或红色、紫红色肿块,界清质软,数月内生长迅速。皮肤血管瘤(cutaneous hemangiomas)是儿童常见的先天性皮肤良性肿瘤,激光是早期干预和 Based on the cellular biology of vascular disease, Mulliken and Glowacki [1] proposed in 1982 that they be clearly divided into two major groups, hemangiomas and vascular malformations. In 1996, the International Association of Vascular Abnormalities (ISSVA) developed a new classification criteria for vascular disease [2]. So hemangioma is a kind of congenital benign tumor characterized by vascular endothelial cell hyperplasia, which is characterized by bright red patches or red and purplish red lumps appearing at birth or shortly after birth, the boundary is clear and soft, and grows rapidly within a few months . Cutaneous hemangiomas are common congenital benign tumors of the skin in children. Laser is an early intervention and
