Nephrotic syndrome and primary tubular amyloidosis in a child: a case report

Nephrotic syndrome in a 19-month-old child was associated with an unusual form of primary renal amyloidosis. The amyloid deposit was in the tubulo-interstitium and not in the glomeruli. Although the deposit did not stain with Congo red, it had the ultrastructural characteristics of amyloid. The patient had resistant nephrotic syndrome, and he subsequently developed microhaematuria and glucosuria.
