Abstract
This report describes the renal pathology in three siblings with hereditary nephritis. All three cases showed combined features of chronic glomerulonephritis, pyelonephritis, and interstitial nephritis. Foam cells were seen in only one case. These findings support the contention of Krickstein, Gloor, and Balogh (1966) that the renal changes in hereditary nephritis are those of a mixed nephritis.
