Treatment of nevi aranei with the pulsed tunable dye laser at 585 nm.

One hundred children aged < or = 12 years with spider nevi of the face have been treated with the SPTL-1 laser. The laser emits pulsed light at a wavelength of 585 nm, with a pulse duration of 450 microseconds. The series included 37 boys and 63 girls. Patients whose spider nevi were previously treated with other methods were excluded. In 97 cases the lesions were completely removed, but 29% of them required more than one treatment session. Six months later, two patients had mild recurrence of the nevi, which required further treatment. No signs of scarring or of textural or permanent pigmentary changes have been noted.
