Intense Pulsed Light and Q-Switched 1,064-nm Neodymium-Doped Yttrium Aluminum Garnet Laser Treatment for the Scarring Lesion of Discoid Lupus Erythematosus.

Discoid lupus erythematosus (DLE) is a chronic form of cutaneous lupus that can cause permanent scarring. Treatment of DLE includes protection from sunlight and artificial sources of ultraviolet light, as well as systemic and topical medications. The first-line standard therapies are antimalarials and topical steroids. Other systemic therapies include systemic steroid, azathioprine, dapsone, and immunosuppressive agents. Topical tacrolimus and pimecrolimus have also been evaluated. Recent studies reported that several treatments, including pulsed dye laser, CO2 laser, intense pulsed light (IPL), and 1,064-nm long-pulse neodymium-doped yttrium aluminum (Nd:YAG) have been used for the cosmetic treatment of DLE. Here, we report a case of a DLE scar that was successfully treated with a combination therapy of IPL and Q-switched 1,064-nm Nd:YAG laser.
