Very few articles have aimed to illuminate the clinical profiles of vitiligo in China. We conducted this retrospective survey involving 4118 outpatients with vitiligo in order to identify the differences among various clinical types of vitiligo and their associated disorders. Completed questionnaires (3742) were validated and analysed. Of this large cohort, 1565 (41.8%) individuals presented vitiligo vulgaris, followed by focal, segmental, acrofacial, and universal, in that order. The mean age of vitiligo onset was 18.88 years. More than 60% of the patients were affected before 20 years of age. Patients with segmental vitiligo were affected earlier than those with other types of vitiligo (15.55 years; (P < 0.001). More than 74% of the patients presented with focal vitiligo at onset. After 3-5 years, 99% of active vitiligo was worse and shifted from one clinical type to another. However, there was no transformation between acrofacial vitiligo and segmental vitiligo. Compared with the general population, the patients with vitiligo were more likely to be affected by rheumatoid arthritis (P < 0.01), ichthyosis (P < 0.01), chronic urticaria (P < 0.01), or alopecia areata (P < 0.01).
