Treatment of halo nevus with a 308-nm excimer laser: a pilot study.
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.


CONCLUSIONS
Treatment with the 308-nm excimer laser may be an effective treatment of halo nevi located on the face.
