Pathological results for renal and prostate biopsy specimens. A No glomeruli with hypercellularity, capillary wall abnormality, or crescents were identified (renal histology of biopsy specimen, periodic acid-Schiff staining, original magnification, × 400). B Granulomatous inflammation in the interstitium (black arrows) (renal histology of biopsy specimen, periodic acid-methenamine-silver staining, original magnification, × 400). C Immunohistochemistry for CD68 reveals that many inflammatory cells are monocytes/macrophages (red circle). D Necrotizing vasculitis of a small artery with disruption of the elastic lamina (black arrow) (renal histology of biopsy specimen, periodic acid-methenamine-silver staining, original magnification, × 400). E and F Necrotizing vasculitis of a small artery with fibrinoid necrosis (black arrows) (renal histology of biopsy specimen, hematoxylin and eosin staining and elastica-masson staining, original magnification, × 400)
