[The Churg-Strauss syndrome].

Churg-Strauss syndrome (CSS) is medium blood vessels vasculitis with predilection for lungs in patients with bronchial asthma, chronic eosinophilic pneumonia and positive ANCA in the sera in 55-67%. This is a case report of a 60 years old female patient with bronchial asthma, peripherial pulmonary infiltrations, blood eosinophilia, xerophtalmia, tachycardia, chronic rhinosinustis, polyneuropathia and negative imunological tests: CIC (PEG), CRYO, ANA (IIF), RF (aglutination) and ANCA (IFF: pANCA and cANCA; ELISA: proteinase 3, lactoferrin, myeloperoxidase. elastase, cathepsin G). Eosinophilic infiltrates in the tissues tested by skin and salivery gland biopsies were not found. The patient had fulfilled five clinical diagnostic criteria and responded well to imunosuppressive therapy, so this case could be classified as the ANCA negative angiitis and granulomatosis of CSS type.
