title: Membranous nephropathy with crescents in rheumatoid arthritis: a case report.
abstract: A 59-year-old man with long-standing rheumatoid arthritis (RA) developed renal dysfunction, proteinuria and hematuria. Neither gold nor penicillamine had been given. Light microscopy of a renal biopsy specimen revealed membranous nephropathy with crescents of various stages. The possible pathogenesis of such an unusual combination of membranous nephropathy and crescents in RA is discussed.
