Definition / general
  • 2 - 10% of renal biopsies from patients with idiopathic nephrotic syndrome
  • Presents with nephrotic syndrome, more likely to have hypertension and hematuria
  • In adults, represents a heterogeneous group with different clinical courses (Ren Fail 2009;31:192, Nephrol Dial Transplant 2000;15:981)
  • Associated with steroid resistant or steroid dependent minimal change glomerulopathy, focal and segmental glomerulosclerosis
  • Note: minimal change disease, diffuse mesangial hypercellularity and focal and segmental glomerulosclerosis may be a continuum of the same disease
Microscopic (histologic) description
  • Mild mesangial hypercellularity, patent capillary lumens and normal basement membrane thickness
