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.
