case_images: Bilateral pleural effusions and a slight accumulation of ascites were detected on computed tomography (CT) (Figure 1).
case_images: Renal histological analysis. (a) There were diffuse and global endothelial cell enlargements by cytoplasmic swelling with large numbers of inflammatory cells (PAS staining, x400). (b) Mesangiolysis. Partial dissolution of the mesangial matrix (arrowhead) (PAM staining, x400). (c) Endothelial cell swelling (arrowhead) (PAM staining, x400). (d) Endothelial cell swelling occluding the capillary lumen (star) with loss of fenestrations (triangle), and expansion of the subendothelial space (diamond). Fibrin deposition was observed (white arrow). (e) Expansion of the subendothelial space was observed. Immunoperoxidase staining for CD34 (f) and CD68 (g) was positive.

case_images: There was diffuse and global endothelial cell enlargement due to cytoplasmic swelling, with a large number of inflammatory cells (Figure 2(a)). The partial dissolution of the mesangial matrix (mesangiolysis) is also shown (Figure 2(b)). Endothelial cell swelling occluding the capillary lumen with loss of fenestration and expansion of the subendothelial space was observed by electron microscopy (Figures 2(d) and 2(e)). Immunoperoxidase staining for CD34 and CD68 were positive (Figures 2(f) and 2(g)).
