Figure 5. Renal inflammation in acute GVHD after allogeneic bone marrow transplantation (BMT).

Figure 5

In mild renal inflammation (A, PAS stain, ×200), mononuclear cells infiltrated the renal interstitium around the small vessels (arrow). In moderate renal inflammation (B, PAS stain, ×200), infiltration of mononuclear cells expanded into the peritubular interstitium. High magnification of renal inflammation (C, PAS stain, ×400), interstitial cell inflammation was often accompanied by tubulitis (arrow) and peritubular capillaritis (arrowhead). In severe renal inflammation (D, PAS stain, ×200), diffuse interstitial inflammation was noted in the renal cortex.
