Fig 1. Mesangial lupus nephritis (WHO Class IIb) shows mild mesangial expansion by light microscopy, without evidence of endocapillary proliferation. If mesangial immune complexes are present but no mesangial increase is detected by light microscopy, WHO Class IIa is diagnosed (PAS stain; original magnification x200).

Fig 3. Electron-dense mesangial deposits are present in mesangial lupus nephritis WHO Class IIb. There is paramesangial extension of a deposit in the upper left, indicating incipient progression to a proliferative form of lupus nephritis. Reticular aggregates are also present in endothelial cell cytoplasm (transmission electron microscopy; original magnification x8,000).
