Relapsing polychondritis (RP) is an uncommon systemic disorder with a highly variable course. A 17-year-old woman recently presented with a 1-month history of depression, weight loss, chest wall tenderness, hoarseness, and dysphagia. Physical examination revealed cachexia, low-grade fever, pharyngeal erythema, and tenderness of the right auricle, anterior chest, cricothyroid cartilage, and both knees. Laboratory studies included a hematocrit of 34% and a sedimentation rate of 50 mm/hr. Initial improvement on oral corticosteroids was followed by respiratory distress. At that time calcified tracheal cartilage, subglottic stricture, and a saddle nose deformity were present. Despite therapy with steroids, dapsone, and pulse cyclophosphamide, the respiratory distress reoccurred, eventually necessitating tracheostomy. Tracheal cartilage biopsy confirmed the presumptive diagnosis of RP. Bilateral auricular chondritis developed after initial presentation, as did acute vertigo. Although seen in all age groups, less than 10% of cases of RP are seen in children and adolescents. Auricular chondritis (89% of all cases), inflammatory asymetric arthritis (81% of all cases), nasal chondritis (72% of all cases), respiratory tract chondritis (56% of all cases), and audiovestibular abnormalities (46% of all cases) were present in our patient. Relapsing polychondritis may follow a slowly evolving or rapidly progressive course. Appropriate diagnosis and aggressive therapy are recommended to lessen the morbidity and mortality.

A 66-year-old man developed diplopia, ptosis, dysphagia, and acute respiratory failure. The initial diagnosis was myasthenia gravis and prednisolone had been administrated for three years. Because of recurrent upper respiratory infections, prednisolone was tapered off. Two months later, auricular chondritis, arthritis, and conjunctivitis appeared. He was diagnosed as having relapsing polychondritis on the basis of histological findings of the ear lobe biopsy. Reinstituted prednisolone had the effect on the auricular chondritis, arthritis, and conjunctivitis, but no effect on dysphagia, hoarseness, and respiratory failure caused by the deformity of the pharynx and airway. Tracheal collapse usually causes rapid death, so early tracheostomy and the use of endotracheal prostheses have been recommended in patients with airway obstruction from relapsing polychondritis, but such surgical management can only partially open up the large airways and has no effect on smaller airways. In this case tracheostomy and endoluminal stent placement have helped improve the patient's respiratory failure, but have had little effect on its aggravation at night in the supine position. The use of BiPAP after surgical management can be an effective treatment for airway involvement in relapsing polychondritis probably because it keeps the narrowed airways from collapsing, especially at night.

Infections of the laryngeal cartilages occur clinically as local pain, dysphonia, dysphagia or dyspnoea and may lead to destruction of the laryngeal skeleton. We present positron emission tomography/computed tomography (PET-CT) as a new method for detection and monitoring of laryngotracheal chondritis. We prospectively analyzed all patients undergoing PET-CT examination, of whom we were clinically suspicious of laryngeal cartilage chondritis. When a chondritis had been confirmed by PET, therapy was started, and the course of inflammation was monitored. Three patients were selected, where application of PET is demonstrated. We analyzed nine patients, five of them suffering from a present or past cancerous disease of the neck region. Four patients suffered from symptoms that occurred after percutaneous tracheotomy and long-term intubation. Chondritis of the laryngeal skeleton or upper parts of the trachea was diagnosed in seven of nine subjects by using PET-scan. PET-CT provides a reliable tool in diagnosis of laryngeal cartilage chondritis. Furthermore, it is an excellent tool in monitoring objectively presence and grade of an infection. This may play a decisive role in tracheal surgery or to estimate success of conservative therapy.
