Nephrotic syndrome in syngeneic hematopoietic stem cell transplantation recipients: A case report

Figure 3 Renal biopsy findings. A and B: Mesangial hypercellularity was mild. Mesangial matrix expansion was light, and few intracapillary fibrin thrombi were observed. The capillaries were open, showing a few microthromboses. Basement membrane thickening was observed, with a small number of capsule adhesions but no double contours or spikes; C: Immunoglobulin (Ig) G: Diffuse granular immune reactant on the basement membrane (++++); D: IgA: Diffuse granular immune reactant on the basement membrane (+), electron microscopy; E and F: A large number of fibroblasts were seen in Bowman's space. There were epithelial electron dense deposits in the glomeruli.
