case_images: Histological findings of the renal biopsy specimen. a Glomeruli appear normal by light microscopy. The tubule shows slight atrophy, and the interstitium shows mild edema (periodic acid-Schiff (PAS) stain, x100). b PAS stain, x 400. c Electron micrograph. One glomerulus is examined. Glomerular basement membrane (GBM) is mild to moderately irregular with diffuse effacement of epithelial foot processes (black arrows). The mesangial matrix is slightly increased. Electron-dense deposits are not found.

case_images: On electron microscopy, the glomerular basement membrane was moderate to severely irregular in contour, with diffuse effacement of the epithelial foot processes; no electron-dense deposits were found (shown in Fig. 1a-c).
