title: Effectiveness of the Pulse Dye Laser Treatment in a Caucasian Women With Dermatosis Papulosa Nigra.
abstract: Dermatosis papulosa nigra (DPN) is a group of superficial, benign papules commonly in African-American and Asian persons. DPN is considered to be a form of seborrheic keratosis with a specific localization and it is less frequently described in the white population. Treatment modalities include cryosurgery, curettage, electrosurgery, shave removal, and different laser treatment. Pulsed dye laser (PDL) has traditionally been used to treat vascular lesions, but it has been shown to be effective in treatment of lentigines, ephelides, seborrheic keratosis, and rarely DPN. A 43-year-old white female presents with a 5 year-old history of hyperpigmented papules on malar region, neck and upper trunk. The patient is diagnosed with DPN based on her clinical and histopathological findings. The PDL treatment was used successfully. In our opinion PDL is an effective alternative cure option for DPN.
