Based on the history and physical examination, she was diagnosed with focal vitiligo. She was treated with targeted 308 nm excimer light phototherapy three times a week. Five sessions of phototeraphy resulted good response characterized by repigmentation of the lesion without redness and blisters.The therapy aims to achieve the best results with minimal side effects. Phototherapy targets are recommended for local vitiligo and especially for new small lesions as well as pediatric vitiligo. The mechanisms of this phototherapy is to trigger repigmentation, stabilization, immunosuppression and immunomodulation.
