Generalized Licen Planus Treated With Narrowband UV-B Phototherapy: Results From 10 Patients and a Review of the Literature.

Generalized lichen planus can be difficult to treat. One alternative for patients who do not respond to common topical and systemic treatments, such as corticosteroids and oral antihistamines, is phototherapy. Narrowband UV-B phototherapy offers several advantages and is currently the main treatment modality. In this study, we present the results corresponding to 10 patients with generalized lichen planus treated with narrowband UV-B phototherapy. We performed a prospective study of adult patients with generalized lichen planus affecting more than 20% of their body surface area. A complete response was observed in 8 patients (80%) and the disease recurred in 2 of these (recurrence rate, 25%). These rates are similar to those reported in the literature reviewed. Narrowband UV-B phototherapy is a widely used alternative to systemic treatments in GLP, but there are very few reports of its results in the literature.
