Abstract
Fixed solar urticaria (FSU) is an extremely rare type of solar urticaria characterized by urticarial wheals appearing frequently confined to fixed areas of the skin. After a few minutes of exposure to sunlight or other sources of radiation, urticarial lesions can usually be induced exclusively in the same localization. We report a case of delayed onset FSU occurring 6 hours after exposure to ultraviolet A and B light.
