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).

Conditions

  • Facial Dermatoses
  • Seborrheic Keratoses

Interventions

DEVICE

Pulsed dye laser

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.

PROCEDURE

Curettage

A second lesion will be treated with curettage with or without anesthetic, depending on the patient's preference.

PROCEDURE

Electrodesiccation

A third lesion will be treated with electrodesiccation after infiltration of 1% lidocaine with epinephrine.

OTHER

No treatment

A fourth lesion will not be treated and will serve as a control.
