Polymorphous light eruptions
Polymorphous light eruptions occur in vulnerable individuals within hours or days of exposure to sunlight and usually persist for several days. Irritating papules, which may coalesce into plaques, occur on exposed sites. The lesions frequently become excoriated but usually subside within 2-5 days if further exposure is avoided.
Sunscreens and topical corticosteroids have largely replaced systemically administered antimalarials, which were once widely used to suppress intense inflammation. PUVA therapy can be used to desensitize patients to the effects of ultraviolet radiation and, in some cases, suppress recurrences.
