title: Efficacy of a 2-mm spot size lens for the treatment of superficial vascular lesions with a flashlamp-pumped dye laser.
abstract: BACKGROUND
  The flashlamp-pumped dye laser, using either a 3 or 5 mm spot size, is an excellent instrument for the treatment of port-wine stains and other superficial cutaneous vascular lesions. Problems exist with patient acceptance due to prominent and prolonged blue-black discoloration and the pain associated with the treatment.
  
  
  OBJECTIVE
  To assess the effectiveness of a flashlamp-pumped dye laser equipped with a 2 mm spot size lens in the treatment of superficial vascular lesions.
  
  
  METHODS
  Twenty-one patients with telangiectasias, cherry angiomas, and angiokeratomas were treated at a variety of fluences.
  
  
  RESULTS
  Three of 21 patients had complete clearing of their superficial vascular lesions. An improvement of greater than 75% was noted by 11 patients, and six patients noted a 50%-75% improvement. One patient had less than 50% improvement. Less post-treatment discoloration and less pain were noted with the 2 mm spot size lens.
  
  
  CONCLUSIONS
  The 2 mm spot size lens, used with the flashlamp-pumped dye laser is an effective instrument for the treatment of superficial cutaneous vascular lesions.
