In a recent issue of the Archives, Nunez et al1 reported that telangiectatic erythema of cutaneous lupus erythematosus could be successfully treated with a flashlamp pulsed dye laser operating at 585 nm. In a patient with multiple facial telangiectasias without a previous diagnosis of lupus, we observed a case of discoid lupus erythematosus (DLE) seemingly induced after thermal injury by overly intense use of an argon laser attached to a computerized scanning device.
Report of a Case.
A 32-year-old woman with Fitzpatrick type III skin2 presented for treatment of prominent nasal bridge telangiectasias. She had no significant medical history, photosensitivity, or chronic sun damage. An argon laser operating at 514 nm with a computerized scanning device was used. The input fluence from the argon source was 4.9 W with the power meter displaying 4.4 W. The selected fluence was 22 J/cm2 (36 milliseconds per pulse) delivered in
