Actual (reported)DPN is a disorder among darkly pigmented patients, manifested by small, benign, variants of seborrheic keratoses, predominantly on the face. The purpose of this study is to determine the efficacy of a 585 nm PDL for the treatment of Dermatosis Papulosa Nigra, and compare it to therapy with curettage (scraping the lesions off) and electrodesiccation (burning the lesions off).

Four lesions are selected on each subject for study. One lesion will be chosen for treatment with the pulsed dye laser with a 7 mm spot size. A single 10 J/cm2 pulse with 10 ms pulse duration will be used to treat the lesion.
Four lesions are selected on each subject for study. A second lesion will be treated with curettage with or without anesthetic, depending on the patient's preference.
