Glomerulus showing accumulation of plasma-like material in the widened subendothelial area globally (star mark). One of them shows presence of red blood cells in the microaneurysmal space (black arrow) at the tubular pole (x40, periodic acid-schiff methenamine silver stain)

Biopsy revealed 19 viable glomeruli, exhibiting diffuse and global subendothelial widening with frequent microaneurysms [Figure 1].
Ultrastructure of glomerular capillary wall revealing marked widening of the subendothelial spaces by electron-lucent material (star mark) and fibrin tactoids (white arrow). New basement membrane layer is seen on the inner aspect. Overlying podocytes show diffuse effacement of foot processes (x9300, uranyl acetate and lead citrate)
