History: Polymorphous light eruption(PMLE) is an abnormal, recurrent, delayed reactions to sunlight, ranging from erythematous papules, papulovesicles, and plaques to erythema multiforme like lesions on sunlight-exposed surfaces.  Only one clinical form is consistently manifested in any one patient, but combined morphologies may also result..  PMLE affects females 2-3 times more often than males.  The eruption typically occurs in spring typically at the onset of a vacation in a sunny place or at a high altitude and disappears without scarring by the time the patient returns home.
