Clinical Features of Vitiligo and Social Impact on Quality of Life.

Vitiligo is the most common cause of depigmentation and its estimated worldwide prevalence ranges from 0.5% to 2%. The disease is characterized by the development of white macules resulting from a loss of epidermal melanocytes. The term vitiligo (nonsegmental) is now a consensus umbrella term for all forms of generalized vitiligo. Two other subsets of vitiligo are segmental vitiligo and unclassified/undetermined vitiligo, which corresponds to focal disease and rare variants. A series of hypopigmented disorders may masquerade as vitiligo, and some of them need to be ruled out by specific procedures including a skin biopsy. The skin plays an important role in our interaction with the world and any change in the skin colour can have important psychological consequences. In this line, vitiligo has a major impact on quality of life.In this review, we will detail the most recent data on the clinical features of vitiligo and its impact on quality of life.
