Twenty-year follow-up using a postal survey of childhood vitiligo treated with narrowband ultraviolet B phototherapy

Vitiligo is a depigmenting skin disorder with an estimated prevalence of 1%.(1) Childhood-onset vitiligo occurs in approximately a third of all cases.(2) Early-onset childhood vitiligo tends to be a more extensive and progressive type of vitiligo.(3) Narrowband ultraviolet-B (NB-UVB) phototherapy is an effective treatment option in active vitiligo and leads to >75% repigmentation in 14-75% of childhood cases.(4,5) Unfortunately, no evidence is available whether this repigmentation is long-lasting. To date, no data are available on the long-term efficacy and safety of NB-UVB in childhood vitiligo. This article is protected by copyright. All rights reserved
