title: ANCA-positive vasculitis associated with allopurinol therapy.
abstract: The triggers that induce ANCA-positive vasculitis are largely unknown. In a minority of cases, however, the disease appears to be medication-induced. This report provides the first description of a case of ANCA-positive vasculitis associated with allopurinol treatment.
