Goodpasture's syndrome superimposed on membranous nephropathy. A case report.

We describe a patient with idiopathic membranous glomerulopathy who developed acute deterioration in renal function; this was associated with hemoptysis, severe hypertension, and anti-glomerular basement membrane (anti-GBM) antibody in the serum. Despite aggressive therapy with plasmapheresis, cyclophosphamide and prednisone, the patient progressed to end-stage renal failure and is on maintenance hemodialysis.
