We present the case of a 38-year-old male who reported to our practice with multiple newly developed halos around 26 existing nevi on his trunk. The halo nevi developed after the patient, who lived in the northeast, spent 2 months on a lake in Alabama, with intense heat and sun exposure. This case is remarkable in that it points to ultraviolet exposure as one instigating factor in the development of halo nevi, the development of which is incompletely understood.
