Vitiligo is a condition that causes depigmentation of patches of skin. It occurs when melanocytes, the cells responsible for skin pigmentation, die or are unable to function. The cause of vitiligo is unknown, but research suggests that it may arise from autoimmune, genetic, oxidative stress, neural,or viral causes.The incidence worldwide is less than 1%.The most common form is non-segmental vitiligo.There is no cure for vitiligo, but there are a number of treatments that improve the condition. Treatment options generally fall into four groups:sunblock,skin camouflage,reversal and de-pigmenting.

白癜风是一种色素脱失形成皮肤斑块的一种病症.当负责皮肤色素沉着的黑色素细胞凋亡或者丧失功能时,此病便会发生.白癜风的病因尚未明确,但研究表明,它可以由自身免疫、遗传基因、氧化应激或者病毒等因素导致.该病在全世界范围内发生率小于百分之一.非节段性白癜风是白癜风最常见的类型.目前白癜风还不能治愈,但仍有很多治疗方法可以改善症状.治疗手段大致分为四个方面：1.防晒 2.选择合适的护肤品 3.逆向疗法 4.脱色疗法

注：根据我的了解,逆向疗法好像也叫脱色疗法,所以治疗手段那里它分为了两点有点不合适,但不管了,原文如此,照文翻译而已,如想进一步证实,请参阅别的参考书~
