title: Secondary renal amyloidosis due to long-standing tubulointerstitial nephritis in a patient with Sjögren syndrome.
abstract: A 53-year-old patient with long-standing primary Sjögren syndrome presented with acute renal failure and nephrotic syndrome caused by secondary (AA) renal amyloidosis. Ten years before, he had been admitted because of exacerbation of the systemic disease. At that time, a pseudolymphoma of the kidney was diagnosed. To our knowledge, this is the first report of a patient with primary Sjögren syndrome and secondary (AA) amyloidosis with amyloid deposition in the kidneys causing nephrotic syndrome.
