Abstract

Vitiligo is defined as an acquired, chronic, pigmentary disorder characterized by white macules that usually increase in size over time. These correspond to an epidermal melanocyte loss of function, and in some cases, to those in the hair follicle. The worldwide prevalence is of 0.5 to 2%, affecting all races and men and women equally. Multiple theories that try to explain the pathogenesis of the disease have been proposed, among them, biochemical, neural and autoimmune hypothesis, the latter being the most popular. The different theories may converge to contribute to melanocyte loss, supporting a multifactorial etiology referred to as the convergence theory.
The diagnosis is clinical and may be aided by the use of Wood`s lamp. We have a great quantity of treatments available that bear advantages and disadvantages, but none with 100% effectiveness in all patients.
