A Study on the Effect of Nevus Flammeus Treatment by Flashlamp Pumped Pulsed Dye Laser

Ninety patients(average age 18 years 10 months) with nevus flammeus were treated with the flashlamp pumped pulsed dye laser(Candela Laser Corp., Wayland, Mass., SPTL-1). With an average of 3 treatments, more than 75% lightening was achieved in 36 patients(40.0%), 50% to 75% lightening in 42 patients(46.7%), 25% to 50% lightening in 6 patients(6.7%), and less than 25% lightening in 6 patients(6.7 %), The percentage of lightening was increased as the number of treatments increased. The overall more than 50% lightening was achieved in 7 patients(l00%) of pink lesion treated, in 44 patients(89.8%) of red lesion treated, and in 27 patients(79.4%) of purple lesion treated.

There were complications such as cutaneous hyperpigmentations in 21 patients(23.3 %), hypopigmentations in 3 patients(3.3%). and atrophic scar in 1 patient(1.l%). All complications were transient and disappeared completely.
