Multiple Halo Nevi Induced by Intense Sun Exposure
Abstract:
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.

Nucleotide Excision Repair
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
