Treatment of nevi aranei by means of an argon laser.

Sixteen patients with 18 telangiectatic lesions have been treated by means of an argon laser over a 7-year period. The physics and medical uses of the laser are reviewed and the pathology of the laser wound is discussed. Seventeen of 18 lesions responded satisfactorily and suggest that the argon laser is a simple, effective clinical tool for the treatment of cutaneous vascular lesions.
