We present the case of a 50-year-old man who underwent kidney biopsy for nephrotic syndrome. In addition to a membranous pattern, anti-glomerular basement membrane (anti-GBM) staining was noted before manifestations of anti-GBM disease. Hematuria and renal failure ensued 2 weeks later. In addition, he had simultaneous circulating levels of anti-GBM antibody and both perinuclear (P-) and cytoplasmic (C-) antineutrophil cytoplasmic antibody (ANCA).
