Abstract:
BACKGROUND: Vitiligo was divided into two types, segmental and non-segmental vitiligo. OBJECTIVE: The purpose of our study is to investigate the clinical differences of segmental and non-segmental vitiligo. METHODS: A cross-sectional study, using standard questionnaire items on 1190 cases of vitiligo was performed. RESULTS: The results were summarized as follows 1. The non-segmental vitiligo was 2.4fold more common than segmental vitiligo. 2. The mean age of onset was older in non-segmental vitiligo than in segmental vitiligo. 3. The mean duration was longer in non-segmental vitiligo. 4. The depigmented area was larger in non-segmental vitiligo. 5. The incidences of Koebner phenomenon, progressiveness and mucosal involvement were more common in non-segmental vitiligo. 6. There were no differences about sex ratio, blood typing, family history, and associated disorders. CONCLUSION: Segmental and non-segmental vitiligo differ substantially in various clinical manifestations, which suggests that two types of vitiligo have different pathogenic mechanism.
