Systemic lupus erythematosus associated with erythema multiforme: A rare case report of Rowell's syndrome

Key Clinical MessageAlthough it is very uncommon, SLE may initially present with recurrent episodes of EM-like rash. Despite the various possibilities underlying their association, prompt identification, and treatment of SLE in patients presenting with EM is important to prevent death or serious organ damage.AbstractRowell's syndrome (RS) is an uncommon presentation of systemic lupus erythematosus (SLE) with erythema multiforme (EM)-like lesions associated with specific serological changes, including positive rheumatoid factor (RF), speckled antinuclear antibody (ANA), positive rheumatoid factor, or anti-La antibodies in the serum. Our case, a 41-year-old male, presented with features of EM. Upon investigation, we identified underlying systemic lupus erythematosus, marking a rare instance of SLE presenting for the first time as EM. Classical or true EM is precipitated by trigger factors such as infective agents like the herpes simplex virus, Mycoplasma pneumoniae, drugs like anticonvulsants, antibiotics, and non-steroid anti-inflammatory drugs, any underlying malignancy, or connective tissue disorders, and is not associated with any specific serological abnormalities. EM cases associated with LE lesions where an EM trigger factor is missing are considered an RS diagnostic criterion. In this case report, the importance of considering SLE in patients presenting initially with recurrent episodes of EM-like rash is emphasized. RS should be considered, especially when there is no ...
