[Report of a case of allergic granulomatous vasculitis (Churg-Strauss syndrome)].

A 35 year female with a previous history of asthma came to our observation about 10 months ago. She was dyspneic, showed small nodules (2 to 5 mm) in arms, hands and legs and had radiological evidence of pulmonary granulomatosis and pleural effusion. Diagnosis was made by means of cutaneous biopsy showing a necrotic granulomatous vasculitic lesions with eosinophilic infiltration and giant cells, consistent with allergic granulomatosis of Churg-Strauss syndrome. Steroid therapy alone (prednisone 1 mg/kg/die) led to a rapid and complete clinical and humoral remission. The patient is still doing an alternate day prednisone therapy (15 mg) and is well after a 10 months follow-up.
