FIBRILLARY GLOMERULONEPHRITIS WITHOUT IMMUNOGLOBULIN DEPOSITS IN THE KIDNEY

Three patients are presented, who by electron microscopy, showed promi nent fibrillary deposits in the glomeruli, and in two, also around the tubules. By immunohistology these two cases had no immunoglobulins in either glomeruli or around the tubules. In the third case, which prob ably represents a slightly different form of the disease, minor deposi ts of IgM were found in the glomeruli, while fibrillary deposits were extensive and widespread. It is suggested that precursors of fibrillar y deposits may not be the same in all cases.
