先天性黑色素痣(Congenital melanocytic nevus)是色素痣的一种类型,新生儿发生率约为1%。黑色素痣影响美观,并有一定概率的恶变倾向。手术治疗是目前首选的方法,但较大面积的黑色素痣切除后,创面面积过大,会留下大片瘢痕,影响外观。近年来,激光的发展为先天性黑色素痣提供了更有效率的治疗,包括红宝石激光器、翠绿宝石激光器、Nd∶YAG激光器,以及CO2激光器、Er∶YAG等,本文就激光治疗先天性黑色素痣的进展进行综述。

Congenital melanocytic nevus （CMN） is a kind of inborn pigmented nevus and occurs in approximately 1% of newborns. CMN may be cosmetically disfigured, also has possibility to malignant transformation. The most appropriate treatment for CMN is surgical excision. However, for large area of CMN, surgical excision would cosmetically cause scar in sensitive areas or in inoperable locations which is unsatisfactory. The lasers that have been studied for the treatment of CMN include pigment-specific lasers （ruby, alexandrite, Nd：YAG）, as well as ablative laser treatment with C02 laser and Er：YAG. In this paper, the progress of laser treatment in CMN was reviewed.
