皮肤血管瘤是胚胎期血管形成过程中出现的一种先天性发育不良,属错构瘤性质,起源于中胚层,是先天性毛细血管增生扩张的良性肿瘤,多在出生时或出生后不久发生。少数在儿童期或成人期开始发病,随年龄增长而增大,直至成年期停止[1]。血管瘤发病率出生时为1.1%~2.6%,1岁内发病率可高达10%~12%[2]。多数侵犯头、颈部皮肤,但粘膜、肝脏、腿和肌肉等处也可发生。该肿瘤在生长过程中,可引起一些合并症,如遇外伤或感染时可引起出血或溃疡、动静脉瘘和血小板减
Cutaneous hemangioma is a congenital dysplasia in the process of embryonic vascularization. It belongs to the mesoderm and is a benign tumor with congenital capillary proliferation and expansion. It often occurs at birth or shortly after birth . A small number of onset in childhood or adulthood, increased with age, until the adulthood stopped [1]. The incidence of hemangiomas at birth is 1.1% ~ 2.6%, 1 year old the incidence rate can be as high as 10% to 12% [2]. Most violations of the head and neck skin, but mucosa, liver, legs and muscles can occur at other places. The tumor in the growth process, can cause some complications, such as case of trauma or infection can cause bleeding or ulcers, arteriovenous fistula and thrombocytopenia
