Abstract
ABSTRACT
The relationship between erythema multiforme (EM) and allergic contact dermatitis (ACD) remains unclear. There have been multiple reports of EM-like lesions occurring in conjunction with or presenting after ACD; however, various definitions and terminologies have been used to denote the patient's diagnosis in these cases. In this systematic review, we summarize the key presenting features of recent cases of EM-like eruptions associated with ACD, as well as diagnostic findings, responsible allergens, treatments, and outcomes. We propose that, whenever possible, these cases should be classified into 2 distinct categories: (1) EM-like ACD and (2) EM after ACD (ACD-induced EM). Because the clinical courses, potential complications, and treatment plans differ between the two, a critical need exists for further characterization and distinguishment of EM-like ACD and ACD-induced EM.
