摘要To the editor:The diagnosis of relapsing polychondritis may be difficult in the absence of typical auricular or nasal involvement.Airway involvement is a major cause of morbidity and mortality.A 43-year-old man was admitted to our hospital because of a 2-month history of persistent fever and dry cough.He had a history of epilepsy at age 23 years,from which he recovered after treatment with sodium valproate.He also had a history of hearing loss for six months.During the 2 months before hospital admission,he had a fever of 38℃ or higher nearly every day,and he was treated with antibiotics,but not effective.Physical examination revealed the patient with binaural hearing loss.The erythrocyte sedimentation rate (ESR) was 124 mm/h.The white cell count was 5.44 × 109/L,with 61.2％ neutrophils.Pulmonary function showed obstructive ventilatory dysfunction.
