Belimumab treatment in rhupus: A case report with severe skin involvement

Patients with rhupus characteristically exhibit symmetric polyarthritis and clinical manifestations suggestive of systemic lupus erythematosus (malar rash, photosensitivity, hematological manifestations, serositis, and/or skin involvement) and positive anti‐dsDNA. Treatment is unclear and it can include disease‐modifying rheumatic drugs like hydroxyl chloroquine, or methotrexate or, in refractory cases, rituximab or abatacept. We report a case of 31‐year‐old female who present with rhupus with skin acute lesions treated with belimumab. This is the first case of rhupus treated with this drug described in the literature.
