We report the case of a 71 year-old man that was admitted to the hospi
tal because of acute renal failure and evidence in serum of anti-glome
rular basement membrane antibodies associated with anti-neutrophil cyt
oplasmic antibodies having a perinuclear pattern. The evolution shows
clinical and patological features of anti-glomerular basement membrane
antibodies disease and Wegener's granulomatosis. We review the publis
ted bibliography as well as clinical and pathologic features of both d
iseases.
