ABSTRACT
Lasers are presently used to treat a wide spectrum of congenital and acquired cutaneous vascular lesions. Before the advent of laser technology, many of these conditions had no acceptable or effective means of treatment. The argon and other continuous wave and quasicontinuous wave lasers were used in the 1970s and in the early 1980s to treat port wine stains. Impressive lightening of mature port wine stains was achieved, but treatment of immature, pale, macular lesions often resulted in scarring (1,2).
