Typically, the first episode develops in the spring following the first exposure to intense sun. Further episodes of the irritable rash occur several hours to days following subsequent sun exposure.<unk>  appears on areas of the skin newly exposed to sunlight such as the visible part of the neckline, backs of hands, arms and legs, and feet, but less commonly the face. At these areas, there may be feelings of burning and severe itching. Smooth red-topped small papules which merge into plaques, small fluid-filled blisters (papulovesicles) and less commonly target-shaped lesions which look like erythema multiforme may be visible. In addition, it may occur in other parts of the body in some people treated for inflammatory skin diseases with phototherapy. The rash is usually quite symmetrical and characteristic for each individual, appearing similar with each recurrence, but can look dissimilar in different people. Fever, fatigue and headaches have been previously associated with the eruption, but are rare. The rash may persist for many days to a couple of weeks, resolving spontaneously without scarring as long as further sunlight exposure is avoided. Recurring yearly, the eruption can sometimes last longer than a few days if persistent and repeated sun exposure occurs. However, the "hardening" effect, with respite during the later summer, frequently occurs with gradual exposure of sunlight, eventually leading to significant improvement.
