title: Polyarteritis nodosa in hairy cell leukemia: treatment with interferon-alpha.
abstract: Polyarteritis nodosa (PAN) is a rare but well described complication of hairy cell leukemia, with 17 cases reported. Treatment has been with prednisone or cyclophosphamide, with variable results. We describe a case of PAN associated with hairy cell leukemia treated with interferon-alpha with autopsy proven resolution of the vasculitis.
