Renal biopsy showed amorphous deposits in the mesangial areas, some glomerular capillary walls and in the vascular poles (Figure 1).
Electron microscopy showed expanded mesangial matrix by amyloid deposits (A), which are characterized by non-branching fibrils arranged in random array (B). (A: X4,000, B: X35,000).
