title: Pulsed dye laser treatment of port-wine stains in pigmented skin.
abstract: BACKGROUND
  Little information is available on pulsed dye laser treatment of darker Fitzpatrick skin types.
  
  
  METHODS
  We retrospectively reviewed our clinical experience treating mainly facial (12/13) port-wine stains (PWSs) in 13 patients of skin type V, whose ages ranged from 3 to 65 years.
  
  
  RESULTS
  The response was excellent in 2 patients, good or moderate in 4 each, slight in 1, and poor in 2. Hyperpigmentation occurred in 6 patients and hypopigmentation in 1, which improved despite continuing treatment. Limited atrophic scarring developed in two patients. Although these results were less good and side effects more frequent than described in skin types I to IV, 6 patients (46%) achieved a good or excellent response and 85 (87.6%) of the total 97 laser treatments were not associated with significant problems.
  
  
  CONCLUSIONS
  Patients of skin type V with a PWS should not be excluded from pulsed dye laser therapy, provided that treatment expectations and risks are fully discussed.
