Clinical Symptoms of Relapsing Polychondritis
The most common symptoms of relapsing polychondritis are swelling and erythema of the ears (88% of patients) and arthralgias (81%), with respiratory involvement occurring in over 50% of patients. 1
Primary Clinical Manifestations
Cartilaginous Involvement
The hallmark features involve recurrent inflammation and destruction of cartilage structures:
- Auricular chondritis: Painful, red, swollen ears (88% of patients) - typically spares the earlobes which lack cartilage 1
- Nasal chondritis: Inflammation of nasal cartilage leading to saddle-nose deformity
- Joint involvement: Arthralgias or arthritis (81% of patients) 1
Respiratory Manifestations
Airway involvement represents the most serious and life-threatening complication:
- Persistent or chronic cough: Often one of the first and most important symptoms, signifying respiratory tract involvement 1
- Wheezing and stridor: From laryngotracheal inflammation
- Dyspnea: Progressive airway compromise
- Hoarseness or aphonia: Laryngeal cartilage involvement
- Tenderness over laryngotracheal cartilage 1
All locations of respiratory cartilage can be affected, including external nares, nasal septum, eustachian tubes, epiglottis, larynx, thyroid, cricoid, arytenoid, trachea, and bronchi 1. Respiratory symptoms are the presenting features in up to 25% of patients 1.
Disease Pattern and Demographics
- Age at diagnosis: Mean age 51 years 1
- Sex distribution: Equal male-to-female ratio 1
- Disease course: Relapsing pattern in 86% of patients; continuous symptoms in 14% 1
Additional Systemic Manifestations
Beyond the classic triad of auricular, nasal, and respiratory involvement, patients may present with:
- Ocular inflammation 2, 3
- Audiovestibular symptoms 3
- Skin manifestations 3
- Cardiovascular involvement (less common but prognostically significant) 4
Critical Clinical Pitfalls
Early diagnosis is frequently delayed because common symptoms may be absent in nearly half of cases during early stages 5. The diagnosis often becomes apparent only after chondritis develops in patients initially evaluated for isolated joint abnormalities, ocular, cutaneous, or audiovestibular complaints 1, 3.
Respiratory involvement carries the highest mortality risk - mortality is frequently related to respiratory complications from progressive airway collapse and stenosis 1. Patients with laryngotracheobronchial involvement face life-threatening local obstructions 6.
The pleomorphic nature of the disease with non-specific symptoms at onset contributes to diagnostic delays 7. Clinicians must maintain high suspicion when patients present with unexplained combinations of auricular inflammation, arthritis, and respiratory symptoms, particularly in middle-aged adults.
