Findings of the second biopsy of a transplanted kidney at our hospital: light microscopy using PAS (A), fluorescence microscopy for IgG (B), and EM (C). The glomeruli showed collapse, but no segmental sclerosis was observed. The findings were consistent with minimal change disease, and, as with the previous biopsy, no deposition of immunoglobulins such as IgG was detected. On EM of the transplant kidney, the degree of podocyte foot process effacement had improved to approximately 10%
