Abstract
In the last two decades, 308-nm excimer laser has been increasingly recognized as a therapeutic alternative for several dermatological conditions, being currently FDA approved for the treatment of localized vitiligo and moderately severe localized psoriasis unresponsive to topical treatments. We describe the case of a 17-year-old with a recalcitrant form of dermatitis occupying the entire perioral region, previously unresponsive to several treatments, who was treated with 308-nm excimer laser with an excellent result. 308-nm monochromatic excimer laser has several advantages over other types of phototherapy, including lower UV dose exposure, shorter courses of therapy and a better sparing of adjacent tissue. Although infrequently used, 308-nm excimer laser certainly has a vast potential in Dermatology, particularly regarding recalcitrant and localized inflammatory conditions, such as the one we present.
