Interposition of monocytes in cryoglobulinemic glomerulnephritis. Two monocytes containing lysosomes are interposed, together with electron-dense subendothelial deposits, between the glomerular basement membrane and the newly formed basement-membrane-like material of the double-contoured capillary wall. The interposition of monocytes is a distinctive feature of cryoglobulinemic glomerulnephritis [17,18]. Mesangial matrix and mesangial cell interposition, however, usually are less evident than in idiopathic membranoproliferative glomerulonephritis, as is glomerular sclerosis.
