Aim. Some evidences have showed that vascular lasers may be effective in the treatment of cutaneous viral warts (CVW). The aim of our study was to evaluate the effects of treatment with KTP laser (532 nm) in recalcitrant CVW.
Methods. We treated 44 recalcitrant CVW observed in 26 patients with a KTP laser, using a scanner system at fluences of 30-35 J/cm2, in association with a dynamic cooling device. Treatment was repeated monthly as necessary for a maximum of 5 sessions.
Results. Within 3 sessions, eradication was obtained in 75% of CVW (mostly hand and periungual lesions). At follow-up evaluations of 12-36 months, no recurrences were noted in CVW previously eradicated. Treatment was well-tolerated, without permanent adverse effects, including nail dystrophy, pigmentary or textural changes. Intraoperative pain was usually mild and well controlled by skin cooling. Postoperative events (erythema, crusting and blistering) were mild and transient.
Conclusion. Our results suggest that the KTP laser can be considered a useful and safe approach to recalcitrant CVW, especially with regard to periungual and hand lesions.
