Kidney biopsy findings from patient II-2. (A, B) Light microscopy shows mesangial proliferative, thickening and hyalinization of the renal arteriolar wall, and “onion skinning” of small renal arteries. (Hematoxylin and eosin stain, original magnification: ×400; Masson stain, original magnification: ×200). (C) Immunofluorescence microscopy shows bright granular C3 staining in the mesangium and along capillary walls. Staining for all Igs and C1q was negative. (Original magnification: ×400). (D) Electron microscopy shows electron-dense material in the mesangium and diffuse foot-process effacement. (Original magnification: ×8000).
