KIDNEY - Amyloidosis

The kidney appears to be of normal size; it is however, pale and the cortex and medulla sharply demarcated; the outer surface shows an occasional minute cyst and a fine granularity. the renal pelvis appears normal. There is no thrombosis of the tributaries of the renal vein.
This man appears to have been first seen in November 1976 at the age of 63; he had had gout for 13 years, which had been treated and, on the present admission, showed evidence of nephrotic syndrome. Investigation had established multiple myeloma with renal amyloidosis. He subsequently developed an acute renal failure and died in renal failure.
