title: Acquired port-wine stain in a pediatric patient.
abstract: BACKGROUND
  Acquired port-wine stains (PWSs) are vascular lesions that are identical to congenital PWSs morphologically and histopathologically.
  
  
  OBJECTIVE
  Because acquired PWSs are rarely seen in adult and pediatric patients, we present a 9-year-old boy with an acquired PWS on his left forearm.
  
  
  CONCLUSIONS
  None of the proposed etiologies, such as trauma, chronic sun exposure, or hormonal medication, was applicable to our patient, and a literature review showed us that acquired PWSs give a faster and better response to pulsed dye laser therapy than congenital lesions do.
