Background:
The treatment of halo nevus is controversial and ranges from observation requiring no therapy to excision biopsy.
Objective:
To assess the efficacy of excimer laser for the treatment of halo nevus.
Methods:
Four patients with halo nevus on the face were treated by excimer laser three times a week until they achieved 75% pigmentation or a maximum of 36 treatment sessions. They were assessed visually by comparing photographs taken before and at the end of treatment.
Results:
Two patients re-pigmented completely and two showed 80% pigmentation. The number of sessions ranged from seven to 35. The study is limited by the small number of patients.
Conclusion:
Treatment with the 308-nm excimer laser may be an effective treatment of halo nevi located on the face.
