Figure 1.
(A) –PAS-stained allograft biopsy (400×) reveals intracapillary fibrin thrombi (arrowhead), moderate increase in mesangial matrix and cellularity and global reduplication of glomerular capillary walls. A small capillary (top left corner) also shows a luminal fibrin thrombus. (B) PAMM Silver stained section (400×) shows another glomerulus with moderate increase in mesangial matrix and cellularity, and highlights the splitting of glomerular capillary walls. Luminal fibrin thrombi (arrowhead) are also noted.
