Carbon dioxide laser treatment of external genital lesions.

Our entire clinical experience with the use of carbon dioxide (CO2) laser in the treatment of 67 patients with diverse external genital lesions is presented. Successful eradication was accomplished in 61 patients with wide distribution of condylomatous lesions, with 88 per cent responding to a single laser treatment. Excellent cosmetic results, as well as complete disappearance of balanitis xerotica obliterans and erythroplasia of Queyrat, were observed in 5 additional patients. Laser therapy, although not an established treatment option, appears to be a safe alternative and should be considered in those patients with recurrent genital condylomata, balanitis xerotica obliterans, as well as erythroplasia of Queyrat, not responding to well-known treatment modalities.
