OBJECTIVE: The purpose of this study was to assess the efficacy of monochromatic UVA laser in the treatment of palmoplantar pustular psoriasis (PPP). BACKGROUND DATA: UVA-1 laser (355 nm) has been reported to be safe and effective in the treatment of psoriasis, but the range of potential applications has not been fully explored. METHODS: Thirty-three patients were enrolled in an open prospective study. Patients were treated from two to four times weekly at a fixed dose of 80-140 J/cm(2). Follow-up was 3 months. Clinical remission was observed in all patients who completed the study, with limited side effects (mild post-treatment erythema). CONCLUSIONS: We report for the first time that UVA-1 laser produces a therapeutic response in PPP.
