Silent tracheobronchial chondritis in a patient with a delayed diagnosis of relapsing polychondritis

Relapsing polychondritis is a very rare autoimmune disease characterised by a relapsing inflammation of hyaline, elastic and fibrous cartilaginous tissues. The incidence is estimated to be between 3.5 and 4.5 per million people per year. Clinical signs and symptoms can be very subtle, and if left undiagnosed for a prolonged period, airway involvement can cause fibrosis of the tracheobronchial wall, leading to a fixed tracheobronchial stenosis. Eventually, this can progress to life-threatening tracheobronchomalacia due to irreversible damage and loss of tissue integrity. We report an elderly man who presented with recurrent bilateral ear inflammation and intermittent polyarthritis who was diagnosed with relapsing polychondritis with asymptomatic involvement of his large airways.
