A 5 year old child suffering from nephrotic syndrome is responding well to steroid therapy. What would be the most likely finding on light microscopy:
No finding
Basement membrabne thickening
Hypercellular glomeruli
Fusion of foot processes
Light microscopy in minimal change disease shows no significant abnormality. Electron microscopy shows obliteration of epithelial cell footprocess. Immunofluorescence shows absence of immunoglobulin or complement deposition.
