Rosai-Dorfman As a Clinical Mimicker of Relapsing Polychondritis

Rosai-Dorfman disease is an uncommon non–Langerhans cell histiocytosis. Typical Rosai-Dorfman disease presents with bilateral cervical lymphadenopathy, fever, anemia, and polyclonal hypergammaglobulinemia. Extranodal disease has been reported in 43% of cases, with the skin involved in 10% of such cases.1 We describe an unusual instance of Rosai-Dorfman disease presenting with bilateral ear nodules and airway involvement, mimicking relapsing polychondritis.
