THE RENAL LESION IN HYPERPARATHYROIDISM

Abstract
Details of 3 cases are given. Chronic hyperparathyroidism is associated with distinctive microscopic changes in the kidney interstitial fibrosis, calcification and infiltraton by lymphocytes and plasma cells, cystic tubular dilatation, thickening and sometimes calcification of tubular basement membranes, relative absence of active glomerulitis or involvement of tubular epithelial cells. The microscopic appearance of the kidney may be distinguished from that of acute hyperparathyroidism as produced experimentally in animals.
