Abstract:

Vitiligo, an autoimmune disorder characterized by localized and / or generalized depigmentation of the skin and / or mucous membranes, is a well-recognized entity.

Its current topographical classification into segmental, zosteriform and nonsegmental, areata, vulgaris, acrofacialis and mucosal represent its well acclaimed presentations.
