Sarcoidosis and membranous glomerulonephritis: a significant association.

Three patients were seen who had sarcoidosis associated with glomerulonephritis. Subsequent review of published reports of cases in which the two conditions occurred simultaneously showed a pattern of histological type of glomerulonephritis different from that seen in patients without associated disease. In sarcoidosis with glomerulonephritis there appeared to be a dearth of minimal-change disease and an excess of membranous glomerulonephritis compared with the prevalence that would be expected if the renal disease was merely a chance occurrence. These findings may provide evidence for an important relation between sarcoidosis and glomerulonephritis.
