[Psoriasis vulgaris. An indication for lasers?].

Treatment of psoriasis is often complicated and remains a challenge. Along with the many new immunomodulatory approaches, various laser systems have been employed in an attempt to treat chronic plaque psoriasis. These include CO(2), Er:YAG, pulsed dye, 1302 nm Nd:YAG and excimer lasers. After reviewing and critically evaluating the literature, we conclude that the 308 nm excimer laser has proven its efficacy, not only in comparison with other laser systems, but also when compared with conventional 311 nm narrow-band UVB treatment. It is an efficient and promising therapeutic option for treating different forms of psoriasis.
