Abstract:
We report a 35-year-old caucasian female with a history of polymorphic light eruption (PLE) who, after the outbreak of pruritic papules following the first sun exposure of the year, developed target lesions in two different bouts, the first on sun-exposed skin and the second on sun-protected sites. A diagnosis of erythema multiforme (EM) developing as a result of PLE was made. As far as we were able to search in the literature, EM occurring in two bouts has not been described previously. We discuss the differential diagnosis.
