Sudden glottic stenosis caused by cricoarytenoid joint involvement due to rheumatoid arthritis.

A woman with rheumatoid arthritis (RA) experienced glottic stenosis approximately two months after switching from etanercept to tocilizumab. Cricoarytenoid joint (CAJ) arthritis due to RA was diagnosed. An awake tracheostomy saved the relievable airway, and the administration of methylprednisolone and infliximab ameliorated the flare-up and glottic stenosis. A follow-up examination revealed the recovery of the patient's normal voice and good control of RA with infliximab and methotrexate. Although general physicians do not frequently encounter patients with symptomatic CAJ arthritis, this condition should be considered as it can be life-threatening. Therefore, when detected, it should be diagnosed and treated immediately.
