Vitiligo appears to be an acquired condition and may appear at any age. There is an increased incidence in some families. Vitiligo is more noticeable in darker skinned people because of the contrast.
Lesions appear as flat depigmented areas with a darker border.
The edges are sharply defined but irregular. Frequently affected areas are the face, elbows and knees, hands and feet, and genitalia. Also associated are sites of trauma and pressure. Examination is sufficient to confirm the diagnosis. No testing is required.
