Polymorphous light eruption presenting as pinhead papular eruption on the face.
J Drugs Dermatol 2013 Nov;12(11):1285-6
Polymorphic light eruption (PMLE) is the most common of the immunologically mediated photodermatoses. Onset is typically within the first three decades of life and affects females two to three times more than males. It occurs 30 minutes to 1-3 days after sun exposure and usually resolves in 7 to 10 days. Lesions present as non-scarring, erythematous and minimally pruritic papules, vesicles, papulovesicles, plaques or nodules. A pinpoint papular variant of PMLE has been reported in individuals with skin phototype IV-VI, characterized by the development of pinpoint papules, 1 to 2 mm, on sun-exposed areas after ultraviolet radiation. PMLE has a predilection for the arms, forearms, hands, head and neck region, usually with sparing of the face. We report two cases of African-American males who presented with the pinpoint papular variant of PMLE involving the face.
