An unusual presentation of antineutrophil cytoplasmic antibody-associated vasculitis: discrepancy between histopathology and clinical presentation.

A 60-year-old man was admitted to our clinic with dyspnea, hemoptesis, anuria, nephritic syndrome, and a positive myeloperoxidase antineutrophil cytoplasmic antibody titer. He was diagnosed with antineutrophil cytoplasmic antibody-associated vasculitis due to Wegener granulomatosis, microscopic polyangiitis, or drug induction. Unexpectedly, histopathologic examination of the kidney biopsy specimen revealed the diagnosis of noncrescentic and nonnecrotizing glomerulonephritis. We report this case because of the unusual histologic type of renal involvement.
