Vitiligo is a long-term skin condition characterized by patches of the skin losing their pigment. The patches of skin affected become white and usually have sharp margins. The hair from the skin may also become white. Vitiligo affects about 1% of people worldwide and is phenotypically characterized by acquired depigmented patches of skin from which melanocytes (pigment-producing cells) have been lost 1. The most common type is non-segmental generalized vitiligo (hereafter referred to as vitiligo), which presents with widely distributed, usually symmetric, and progressive lesions.
