Primary Sjogren's Syndrome with Renal Pseudolymphoma Featuring Interstitial Nephritis / 대한신장학회잡지

ABSTRACT

A 65 year-old woman with Sjogren's syndrome was found to have renal mass and acute renal failure. Immunopathologic analysis of renal biopsy specimens showed polyclonal lymphocytic interstitial infiltration. Gene rearrangement study of T cell receptor showed a polyclonal pattern. The degree of azotemia and the size of pseudolymphoma diminished dramatically with steroid therapy. This is a case of proven pseudolymphoma that was found as renal mass in Sjogren's syndrome.
