Fig 10. Diffuse proliferative lupus nephritis (WHO Class IV)
with deposits that also stain for IgA (same case as in Figure 9).
Large, sausage-shaped capillary wall deposits with smooth outer
contours, indicating subendothelial location, are present in addition
to scattered granular capillary wall and mesangial deposits. The
segmental nature of deposits is apparent. A similar staining pattern,
but in less intensity, was present for IgM, C3, and much weaker for C4
(immunofluorescence with antisera to IgA; original magnification x400).
