[Focal segmental glomerulosclerosis in a patient with polycythemia vera].

Herein we describe the case of a patient with focal segmental glomerulosclerosis (FSGS) following polycythemia vera (PV) on whom hemodialysis was started 7 years later. A 66-year-old woman who had been treated for PV with hydroxyurea and phlebotomy for three years was referred to our hospital because of nephrotic syndrome. Renal biopsy performed at her local hospital revealed FSGS.
