A man in his 40s presented with a 3-week history of multiple erythematous annular plaques on both legs. The patient reported that these lesions had appeared as erythematous and pruritic papules that had grown in number and size, presenting a centrifugal spread. No associated systemic symptoms were present. Treatment with topical antifungals and corticosteroids had failed to improve the lesions. Six weeks before, the patient had undergone a renal colic that was treated with nonsteroidal anti-inflammatory drugs and opioid derivatives. No insect bites or other triggering factors were recorded. His medical history included penicillin allergy, dyslipidemia, kidney stones, and allergic rhinitis.
