NB-UVB is an expecting treatment for pityriasis rubra pilaris

Pityriasis rubra pilaris (PRP) is an erythematous papulosquamous disorder characterized as a reddish or orange scaling dermatitis with normal skin islands, follicular hyperkeratosis, and keratoderma of the palms and soles. The pathogenesis of this disease and the best treatment remain unclear. Narrowband ultraviolet B (NB-UVB) therapy is one treatment for PRP, although there are few reports on it. Recently, we succeeded in controlling a case of PRP with NB-UVB and report this case with a review of the literature.
