Carbon dioxide laser treatment of verrucae vulgares.

A report is presented on the use of the carbon dioxide (CO2) laser for the removal of recalcitrant warts of hands and feet of 27 patients. Of the 27 patients 22 (81%) required only one laser treatment to eradicate warts and remain free of lesions at the 6-month follow-up visit. The other patients required up to 3 retreatments with the laser during the first 6 months to remain free of lesions at a 6-month follow-up. The CO2 laser provided a bloodless surgical field, accurate control, minimal postoperative pain, and decreased postoperative infection. The authors conclude that, while the CO2 laser is not without its disadvantages, it should be considered an important adjunct in the treatment of difficult, widespread, or recalcitrant verrucae.
