De Novo Atypical Haemolytic Uremic Syndrome after Kidney Transplantation

Figure 2

Histological examination showing thrombotic microangiopathy in a kidney biopsy from renal allograft at day 120 (hematoxylin and eosin). Microthrombi and lucent deposits (arrowheads) are observed in the glomerulus at the right side, with obstruction of a nearby arteriole by eosinophilic material (arrow). Notice the unaffected glomerulus on the left side of the microphotograph. There is no evidence of acute antibody-mediated rejection according to the 2015 Banff classification (g0, ptc0, and no C4d deposit by immunofluorescence (not shown)).
