The Nd:YAG 1064-nm laser treatment involves the delivery of laser light irradiation at wavelength 1064 nm, which allows deeper penetration into thicker tissue compared to shorter-wavelength lasers without direct skin or verruca contact. This laser is also used for treating vascular and pigmented lesions, hair removal, skin rejuvenation, onychomycosis and many other aesthetic and medical treatments.8 A minimum of one to two treatment sessions is needed, with sessions spaced two to three weeks apart. Treatment sessions usually begin using a focused lens with a 2-mm spot under the settings of 1.5- ms pulse duration and energy mode of 8 or 9 (fluence of 255 J/cm2 to 287 J/cm2). A Zimmer cooler is used upon the end of the laser treatment. In the case of our patient, a total of two passes over the wart was applied with each treatment session, and the patient tolerated the treatment very well. Upon the end of the fourth treatment session, the patient’s wart had completely resolved.
We have demonstrated the success of utilizing Nd:YAG 1064-nm laser in treating a verruca that had failed to respond to standard treatment. Dermatologists should consider using this laser therapy early in the course of treating resistant warts since it is well-tolerated by patients, and it provides timely, significant results that help to bring disease remission.
