Abstract

Punctate leukoderma presents as numerous, distinct, round or oval depigmented spots. Recently, laser therapy-induced punctate leukoderma associated with various Q-switched laser and carbon dioxide laser have been reported. A 25-year-old man presented with numerous, discrete, round, confetti-like, depigmented macules on his left neck. He had undergone 3 sessions of 532-nm Q-switched Neodymium: Yttrium-Aluminum-Garnet laser treatment for café-au-lait macules three years ago. After the last laser treatment session, the punctate leukoderma had been developed. We started treatment with the 308-nm excimer laser twice a week. After 7 months of treatment duration, complete repigmentation was achieved without serious adverse effects. We recommend the 308-nm excimer laser as an effective treatment modality for laser therapy-induced punctate leukoderma.

(A) Numerous, discrete, round or oval, confetti-like, depigmented macules on the patient's left neck, which developed after Q-switched Neodymium:Yttrium-Aluminum-Garnet laser treatment for café-au-lait macules on the same location 3 years ago. (B) Complete repigmentation after 58 treatment sessions with the 308-nm excimer laser for 7 months.
