Glomerulonephritis leading to end stage renal disease in a patient with primary Sjögren syndrome.

Renal disease as the sole manifestation of extra-glandular involvement is rare in primary Sjögren's syndrome. We report a case of membranous nephritis presenting with proliferative changes including crescents, which led to renal insufficiency in a patient with primary Sjögren's syndrome. The renal involvement was not associated with cryoglobulinemia.
