Tumor necrosis factor-alpha (TNF-α) inhibitors are a group of biological medications that revolutionized the treatment of rheumatoid arthritis (RA) and several other inflammatory autoimmune diseases. The wide use of these drugs has been associated with some adverse reactions. Erythema multiforme (EM) is an immune-mediated cutaneous disorder that represents a hypersensitivity reaction to infections, vaccines, and some medications. We present a female patient with EM with characteristic skin lesions following anti-TNF-α medication adalimumab for rheumatoid arthritis.
Keywords: adalimumab; anti-tumor necrosis factor-alpha; case report; erythema multiforme; rheumatoid arthritis.
