[Allergic angiitis with granulomatosis: the Churg and Strauss syndrome].

Churg-Strauss Syndrome is a disorder characterized by pulmonary and systemic necrotizing vasculitis, extravascular granulomas, and eosinophilia occurring almost exclusively in patients with asthma or a history of allergy. The clinical manifestations most commonly associated with asthma are mononeuritis multiplex, gastrointestinal, cutaneous, cardiac and renal involvement. ANCA are found in 2/3 of the patients with Churg-Strauss Syndrome and are usually p-ANCA. The treatment of Churg-Strauss Syndrome relies on corticosteroids and cyclophosphamide.
