What causes vitiligo?-2
Type:Uv phototherapy Time:2017-05-19 14:17:35The convergence theory states that stress, accumulation of toxic compounds, infections, autoimmunity, genetic predisposition, altered cellular environment, and impaired melanocyte migration can all contribute to the vitiligo initiation process. Autoimmune mechanisms are likely to underlie generalized vitiligo, while a more localized phenomenon (i.e. the altered activities of sensitive nerves in the skin) may be responsible for segmental or focal vitiligo. A site of a skin physical trauma may develop vitiligo; it is called a ¡°Koebner phenomenon.¡±
