Abstract
Seventeen patients with 22 areas of postsclerotherapy hyperpigmentation lasting from 1 to 7 years were treated with a flashlamp-excited pulsed dye laser at 510 nm with a pulse duration of 300 nanoseconds between 2 to 3 J/cm 2 . Depth of hemosiderin pigmentation ranged from 0.2 to 2.8 mm. Forty-five percent of lesions lightened after treatment with significant lightening occurring in 27% of lesions. Four lesions in two patients developed postinflammatory hyperpigmentation after treatment. There was no significant difference in treatment response to pigment location or laser energy.
