Several therapeutic modalities have been proposed for the treatment of vitiligo either to achive repigmentation in the lesions or to stabilize the disease. Narrow-band UVB therapy has been shown to be effective and safe for use in the management of vitiligo; its wavelength is not so different from 308 nm XeCl excimer laser radiation. We present an open and uncontrolled pilot study of 24 patients (12 men, 12 women) in whom vitiligous patches were treated twice a week, for 9 months with 308 nm XeCl laser radiation. Seven of the 24 patients showed greater than 75% repigmentation, six patients showed repigmentation of between 25 and 75% and six patients showed less than 25% repigmentation. In five patients no signs of repigmentation were noted. The therapeutic benefit was stable during the 12-month follow-up period. Although these results are promising, treatment has so far been limited to small numbers of patients and a short follow-up period. Other prospective studies are needed to assess the efficacy of this treatment modality.
