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.
In Brief
A clinical study evaluating Pulsed dye laser, Curettage, and 2 other interventions for Facial Dermatoses and Seborrheic Keratoses. Completed, enrolled 10 participants across 1 site.
Detailed 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).

Timeline
Interventions
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.
A second lesion will be treated with curettage with or without anesthetic, depending on the patient's preference.
A third lesion will be treated with electrodesiccation after infiltration of 1% lidocaine with epinephrine.
A fourth lesion will not be treated and will serve as a control.
