So far no highly effective treatment has been reported. Previous small studies have suggested that ultraviolet B (UVB) is a good alternative. Methods: This is a retrospective analysis of 29 pityriasis lichenoides patients treated in our institutionwith broad- or narrow-band UVB during the period 1996- 2002. Twenty-one of these patients had one or more previous unsuccessful treatments. Results: Complete response was achieved in 93.1% in both treatment groups, with 73% of them still relapse free after a mean follow-up of 58 and 38 months in broad- and narrow-band UVB treatment groups, respectively. Mild side-effects were observed in about one-third of the patients. Conclusion: We believe both forms of UVB are a good option for pityriasis lichenoides and should be considered as the first line in generalized cases interested in treatment.展开更多
