[Churg-Strauss allergic granulomatous angiitis. Apropos of 3 cases].

The authors report three cases of allergic granulomatous angiitis of Churg Strauss. They review the different problems posed by this vasculitis: its enigmatic relationship with polyarteritis nodosa, its pathophysiology which remains a controversial subject and the possible role of immunotherapy with allergic extracts. In one of these cases, treatment with steroids associated with cyclophosphamide led to a prolonged remission of ten years raising the possibility of a cure.
