a. Immunofluorescence with IgA positive staining in the mesangium, which is diagnostic for IgAN. b. Advanced lesion with diffuse interstitial fibrosis and sclerotic glomerulus. IgAN was confirmed by immunofluorescence. No swollen podocytes indicative of FD are seen (Jones methenamine silver stain; high power field). c. Electron microscopy from paraffin embedded tissue. Small dense deposits in mesangial area. Simultaneously lamellated lipid inclusions (so-called myeloid bodies) are shown.
