Abstract

A 72-year-old woman presented with generalized edema and proteinuria. Renal biopsy disclosed highly organized fibrillary deposits in subendothelial area by electron microscopy. The microfibrils were 14 nm in diameter and randomly arranged. They did not have a microtubular appearance. These materials were negative for Congo red staining. Cryoglobulinemia or paraproteinemia including light chains was not found. So we can diagnose her as fibrillary glomerulonephritis (GN). In fibrillary GN serum complement levels are usually normal except in rare cases with systemic disease. Here we present a rare case of fibrillary GN with unusual hypocomplementemia.
