Recent investigations on vitiligo vulgaris

Abstract

Vitiligo is a depigmenting disorder of the skin caused by destruction of melanocytes. The depigmented skin has several abnormal functions, including some autonomic nervous functions. The inflammatory response in the depigmented skin is muted. Recent genetic and epidemiologic studies indicate that vitiligo affects men and women equally. The prevalence in the population is about one in 200. Vitiligo seems to be transmitted as a polygenic trait. New data suggest that it is not associated with autoimmune endocrine disorders, but more comprehensive studies are required.
