(a) Infiltration of plasma cells and lymphocytes and storiform fibrosis in renal interstitium (hematoxylin and eosin staining ×200). (b) IgG4 staining of renal biopsy (×200). (c) Eosinophil infiltration in interstitial of IgG4-TIN (hematoxylin and eosin staining ×200). (d) IgG4-MN accompanied with TIN. Storiform fibrosis can be observed (periodic acid-methenamine-silver staining ×200). (e) Diffuse infiltration of plasma lymphocytes in thickened ureter wall of IgG4-related ureter disease (hematoxylin and eosin staining ×100). (f) IgG4 staining in IgG4-related bladder disease (HE stain ×400).
