A New Technique for Laser Treatment of Cutaneous Tumors

Abstract

The CO2 laser was used to treat three patients with discrete, cutaneous tumors. For each patient, we established the relationship between the width of the lesions and their maximum thickness, and between pulse energy and the depth of the resultant crater. Optimal parameters for therapy were established from these results.

Pearly Penile Papules: Treatment with the Carbon Dioxide Laser

“…The ability to vaporize well‐delineated areas with high‐power densities has made this laser a very attractive and frequently used therapeutic tool for these types of lesions. More exact approaches to the CO 2 laser treatment of similar types of cutaneous tumors have been suggested; 12 however, satisfactory results can still be achieved based on empiric clinical impressions. In both presented cases the laser parameters were similar, and were chosen based on prior experience with similar dermal tumors and patient outcome.…”

Use of the Carbon Dioxide Laser in Dermatologic Surgery

“…Limitations of this technique include its dependence on the accuracy of the surgeon to judge the depth of the lesion, the lack of precise calculation of power densities and duration of exposure for each treatment, and the inability to reduplicate precisely the treatment at another time by the same surgeon, much less by readers of the surgeon's description of the procedure. One report 4 attempted to rectify the situation by biopsying several different small lesions on each of three patients, judging the depth of the lesions histologically, and calibrating the laser to produce craters of precise width and depth in a single pulse. The power output of the laser was kept constant while the duration of the pulse was varied.…”
