Vitiligo is an acquired skin disorder caused by the disappearance of pigment cells from the epidermis, and results in well defined white patches that are often symmetrically distributed. The lack of melanin pigment makes the lesional skin more sensitive to sunburn. Vitiligo can be cosmetically disfiguring and is a stigmatizing condition, leading to serious psychological problems in daily life. It occurs worldwide in about 1% of the population, mostly between the ages of 10-30 years, and as often in males as in females. The cause is unknown, but might involve genetic factors, autoimmunity, toxic metabolites, and/or a higher vulnerability of melanocytes. Some new treatments for this condition include corticosteroid + UVA treatment, UVB narrow wave band (311 nm) irradiation, and transplantation of autologous pigment cells. In widespread vitiligo, residual pigment can be removed by depigmentation agents. Sunscreens, camouflage products and good guidance may help the patient to better cope with this disease.
白癜风是一种后天性皮肤病,由表皮色素细胞消失引起,表现为边界清晰的白色斑块,常呈对称分布。黑色素的缺乏使病变皮肤对晒伤更敏感。白癜风会在外观上造成毁容,是一种令人感到羞耻的病症,会在日常生活中导致严重的心理问题。全球约1%的人口会患白癜风,大多在10至30岁之间,男女患病几率相同。其病因不明,但可能涉及遗传因素、自身免疫、毒性代谢产物和/或黑素细胞的更高易损性。针对这种病症的一些新疗法包括皮质类固醇+紫外线A治疗、紫外线B窄波段(311纳米)照射以及自体色素细胞移植。对于泛发性白癜风,可使用脱色剂去除残留色素。防晒霜、伪装产品和良好的指导可能有助于患者更好地应对这种疾病。
