First case report of monoclonal IgG3-heavy-chain glomerulonephritis with microtubular structures

摘要

Light microscopy findings. a Mesangial and mild endocapillary proliferations associated with lobular formation of glomerular tufts are observed; periodic acid Schiff stain, original magnification ×200. b Lobular formation of glomerular tufts is marked, and nodular lesions are seen; periodic acid Schiff stain, original magnification ×200. c Double-contour capillary walls are not observable; periodic acid–methenamine silver stain, original magnification ×400
