BACKGROUND: Viral warts are common infectious skin disease induced by human papillomavirus (HPV). Lasers have been used for warts treatment in recent years with variable success rates.

OBJECTIVE: This study aimed to prospectively evaluate combined treatment with Er:YAG laser and long-pulsed Nd:YAG laser compared to Er:YAG laser for the treatment of recalcitrant warts after one session.

MATERIALS AND METHODS: This study included 240 lesions from 24 patients. All the lesions were diagnosed clinically as recalcitrant warts after failure of topical treatment and cryotherapy. About 120 lesions underwent a combined therapy of Er:YAG and long-pulsed (LP) Nd:YAG lasers, and the remaining 120 lesions underwent Er:YAG laser therapy only. The clearance rate was evaluated 5 weeks after and classified by three-graded evaluation: complete response, partial response and poor response.

RESULTS: The clearance rate in the combined Er:YAG + LP Nd:YAG lasers group was, statistically significant, higher than that of the Er:YAG laser group (p = 0.008). The complete response rate was 48% (58 of 120 warts) for the Er:YAG +LP Nd:YAG lasers group and only 29% (35 of 120 warts) for the Er:YAG laser group.

CONCLUSION: The combination of Er:YAG and long-pulsed Nd:YAG lasers is more effective than Er:YAG laser alone in treating recalcitrant warts after single session.
