[Relapsing polychondritis--case report].

Relapsing polychondritis (RP) is a rare systemic inflammatory disease in which recurrent episodes of cartilage inflammation result in destruction of ears, nose and tracheobronchal tract. The joints, eyes, audiovestibular system and cardiovascular system can also be involved. About 30% of patients with RP have coexisting autoimmune disease, or malignant disease like colon, breast, and lung carcinoma, or malignant lymphoma. Pathogenesis is still unknown, and there is no consistent laboratory parameter specific for RP, which makes the diagnosis mainly clinical. Glucocorticoids are a mainstay of medical treatment of RP, whereas newer studies show positive effects of biological therapy. The course of RP is characterized by recurrent episodes of cartilage inflammation, and the prognosis has been recently improved because of improved medical and surgical treatment. We present a case of a patient with RP who was diagnosed 1 month after the development of first symptoms and responded well to glucocorticoid therapy.
