About

Vitiligo is a common acquired depigmentation skin and mucosal disease in dermatology, with or without white hair. Vitiligo with white hair is difficult to treat. Phototherapy and topical therapy are the first line treatment methods for vitiligo. The peripheral leukoplakia irradiation of phototherapy covers the central area of the leukoplakia and performs phototherapy on the edge of the leukoplakia and surrounding normal skin. This study aims to compare the efficacy and safety of peripheral leukoplakia ultraviolet family phototherapy and leukoplakia family combination in the treatment of vitiligo.
