Minimal change nephrotic syndrome associated with extrarenal neurilemmoma.

Nephrotic syndrome may be associated not only with malignant neoplasia, but also rarely with benign solid tumours. Here we report a case of a young woman suffering from nephrotic syndrome, histologically classed as a minimal change glomerular lesion, associated with a posterior mediastinal neurilemmoma (ancient neurilemmoma). Surgical removal of the tumour led to complete cure of the nephrotic syndrome with total symptomatic improvement within 6 months. Scanning of the literature revealed only one case report of an association of spinal neurilemmoma with nephrotic syndrome.
