Abstract
Cutaneous lupus erythematosus (CLE) can present with a wide variety of dermatologic manifestations and is broken down into acute, subacute, and chronic subtypes. Tumid lupus, a variant of CLE, is rarely associated with systemic lupus erythematosus. Lesions of CLE and tumid lupus can mimic multiple other dermatologic conditions. We present a case of a patient with tumid lupus who was initially treated for erythema migrans and systemic symptoms suspected to represent Lyme disease. This article is intended for nurse practitioners, nurses, and other clinicians practicing in dermatology, primary care, urgent care, and emergency medicine settings in the care of patients presenting with annular skin lesions.
