Vitiligo.

Vitiligo is a common disorder afflicting people of all ages around the world. It produces milky white patches of depigmentation that cause significant morbidity due to cosmetic disfigurement. One should distinguish segmental from nonsegmental vitiligo, and be aware the latter is associated with an extremely small risk of associated autoimmune disorders. New therapeutic options offer some additional hope to patients with vitiligo, but more progress in the understanding of its pathogenesis and therapy is still needed.
