The classification of segmental vitiligo on the face.

Segmental vitiligo usually has an onset early in life and spreads rapidly within the affected area. Among 1,300 patients with vitiligo, 191 patients with segmental vitiligo involving the face were evaluated. In this study, the distribution of segmental vitiligo on the face could be classified into 5 patterns which have distinctive features. This classification of facial segmental vitiligo can provide some indication of the future distribution of early lesions if they have begun to spread.
