a common pruritic papular eruption appearing in a few hours and lasting up to several days on skin exposed to shortwave ultraviolet light (UVB); subepidermal edema and deep perivascular lymphocytic infiltration is seen microscopically.

polymorphous light eruption

a common recurrent superficial vascular reaction to sunlight or ultraviolet light in susceptible individuals. Within 1 to 4 days after exposure to the light, small erythematous papules and vesicles appear on otherwise normal skin, then disappear within 2 weeks. A delayed allergic response is a possible cause. Tanning reduces the severity of the reaction.

polymorphous light eruption

, polymorphic light eruption Abbreviation: PMLE
A rash occurring after exposure to sunlight, typically consisting of papules, plaques, or papulovesicles on sun-exposed skin. It is more common in fair-skinned patients and in women than in men or people with darker skin color. The rash is usually itchy but may produce a burning or stinging sensation. Avoiding sun exposure with protective clothing and sunblock helps prevent PMLE. Immune-modulating drugs are available for refractory cases.
