Figure 1. Microscopy of renal biopsy. A. PAS stain demonstrating mesangial expansion and mild segmental sclerosis (arrows). B. Jones stain demonstrating immune deposits (arrows) along glomerular capillaries which are negative for silver stain. C. Immunofluorescence stain for IgM showing 3+ staining on mesangial and capillary loops (arrows). D. Transmission electron microscopy showing numerous immunotactoid deposits composed of slightly curved, microtubular structures with mean diameter of 38.6 nm, hollow cores, and parallel alignment beneath the glomerular basement membrane and mesangium.
