Three hundred and eight nanometre excimer light has been reported to be safe and effective in the treatment of chronic skin diseases, but the range of potential applications has not been fully explored. Our objective was to assess the efficacy of monochromatic excimer light (MEL) in the treatment of prurigo nodularis (PN). Eleven patients were enrolled in this pilot study. Patients were treated weekly and an average of eight sessions of MEL was given. Follow-up was 4 months. Partial or complete clinical and histological remission was observed in all patients who completed the study (81%).
