Background: The classification of segmental vitiligo has been previously reported but more consensus on its classification is required from a large number of patients to predict its spreading and provide valuable clues to the etiology of segmental vitilig. Objectives: To classify segmental vitiligo on the whole body into several distinctive subtypes according to distributions and clinical characteristics. Methods: Total 956 patients with segmental vitiligo were enrolled. A new classification of has been proposed according to distribution patterns. The clinical course of segmental vitiligo, including recurrence rate and patterns, concurrence of non-segmental vitiligo, and treatment response, was assessed. Results: Facial and truncal segmental vitiligo was classified into each 5 patterns. Among 501 patients who had been followed up for at least one year, 55 patients (11%) showed recurrence after stabilization for more than 6 months. Most recurrence happened within the area of each subtype of segmental vitiligo in the new classification (92.7%). Conclusion: Our data suggest that segmental vitiligo has a higher recurrence rate than previously known. This new classification can help dermatologists in patient’s real care
