Vitiligo is a common, often heritable disorder that is progressive in nature. It is characterized by cutaneous macules and patches devoid of pigmentation. The lesions are not readily apparent in lightly pigmented individuals; however, they are easily distinguishable with a Wood lamp examination.
Vitiligo lesions may be localized or generalized, with the latter being more common than the former. Localized vitiligo is restricted to one general area with a segmental or quasidermatomal distribution. Generalized vitiligo implies more than one general area of involvement. In this situation, the macules are usually found on both sides of the trunk, either symmetrically or asymmetrically arrayed.

Sites of involvement

The most common sites of vitiligo skin disorder involvement are the face, neck, and scalp. In generalized vitiligo, mucous membranes are also frequently involved. Most of the time vitilogo occurs around body orifices such as the lips, genitals, gingiva, areolas, and nipples.

Body hair (leukotrichia) in vitiliginous macules may be depigmented. Vitiligo of the scalp usually appears as a localized patch of white or gray hair, but total depigmentation of all scalp hair may occur. Scalp involvement is the most frequent, followed by involvement of the eyebrows, pubic hair, and axillary hair, respectively. Leukotrichia may indicate a poor prognosis in regard to repigmentation. Spontaneous repigmentation of depigmented hair in vitiligo does not occur.
