Vitiligo
Vitiligo is a non-contagious, chronic skin condition where white patches develop on the skin due to depigmentation. The first white patches often occur on the hands, feet, arms, face, or lips. Other common areas for patches to appear are armpits, the groin, the navel, and genitals. About half of all people who have Vitiligo begin to lose pigment before they are 20 years old.
