Successful treatment of discoid lupus erythematosus with argon laser.

Vascular lesions with telangiectasias on visible areas, such as the face, are common in discoid lupus erythematosus (DLE); however, an efficient management of these skin lesions can sometimes be difficult. Since argon laser light is able to specifically coagulate vascular structures, it has been used in the treatment of various vascular skin malformations. Therefore, we addressed the issue whether argon laser treatment could be a therapeutic alternative for this disease. Here, we report on a patient with DLE, who suffered from long-standing erythematous, telangiectatic plaques on the face refractory to standard regimens of therapy. After 2 laser applications, a significant improvement was observed and after 5 sessions of argon laser therapy the treated skin lesions had completely resolved with an excellent cosmetic result. The patient tolerated the laser treatment well without any short-term side effects. These data indicate that argon laser therapy might be a powerful alternative approach in the treatment of vascular skin lesions of DLE.
