Official Title: Efficacy of a 585 nm Pulsed Dye Laser (PDL) for the Treatment of Dermatosis Papulosa Nigra, and Compare it to Therapy With Curettage and Electrodesiccation.

Brief Summary:

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).
