Introduction: Dupilumab is a fully human monoclonal antibody therapy FDA-approved to treat moderate-to-severe atopic dermatitis (AD) by interrupting the pro-inflammatory signaling pathway of interleukins 4 and 13. Common side effects of dupilumab include injection-site reactions, ophthalmic complications, and upper respiratory infections. We discuss the necessity for early recognition and management of dupilumab-induced EAC which has not been previously reported as a potential adverse effect.

Case Report: A 48-year-old woman began treatment with dupilumab for severe AD and subsequently presented with a 3-month history of erythematous annular plaques with trailing scale on the trunk and extremities. She failed treatment with topical corticosteroids as well as topical and oral antifungals prior to being diagnosed with biopsy-confirmed erythema annulare centrifugum (EAC). The condition worsened after replacing dupilumab with tralokinumab but resolved after discontinuation of the drugs and has remained clear since.

Conclusion: EAC is a reactive erythema that typically presents as expanding annular papules and plaques with central clearing and in some cases, trailing scale at the rim of the lesions. There are currently no reports in the literature describing the development of EAC secondary to dupilumab. Clinicians should be aware that EAC may be a potential adverse effect of dupilumab.
