Lupus panniculitis as the initial presentation of systemic lupus erythematosus triggered by COVID-19 infection: case report and literature review.

Abstract

COVID-19 has many complications that affect many systems, including rheumatology and inflammatory skin conditions such as cutaneous lupus erythematosus. Herein, we describe the case of a patient with lupus panniculitis who presented with systemic lupus erythematosus in the setting of recent COVID-19 infection. A 66-year-old female patient presented to the hospital with expanded skin lesions all over her limbs, fever, joint pain, and fatigue. Lab tests and imaging revealed a second recent infection with COVID-19, positive titers of systemic lupus erythematosus antibodies, and biopsy confirmed lupus erythematosus panniculitis. She was treated with oral prednisone and hydroxychloroquine for SLE and symptomatic management for recent COVID-19 infection without ICU admission. Lupus erythematosus panniculitis (LEP) is a rare manifestation of lupus erythematosus. Although some cases of SLE following COVID-19 infection have been reported, lupus panniculitis as the initial presentation of systemic lupus erythematosus in these patients is extremely rare.
