Spontaneous remission of immunotactoid glomerulopathy.

Immunotactoid glomerulopathy (ITG ) is a rare cause of nephrotic syndrome, occurring in approximately 0.1% of native kidney biopsies. We describe a 43-year-old woman who presented with a nephrotic syndrome. Renal biopsy revealed a membranous pattern of glomerular injury. In electron microscopy the subepithelial deposits were comprised of 40 nm wide tubular structures, confirming ITG . During follow-up the patient developed a remission of proteinuria with only supportive treatment.
