ANCA-Negative Pauci-Immune Crescentic Glomerulonephritis Linked with Non-Small Cell Carcinoma of the Lung

Abstract

The association between malignancy and glomerular disease has been appreciated for decades [Baschinsky et al., Am J Kidney Dis 2000;36:E24]. Several types of glomerular injury in patients with cancer have been recognized [Morikawa et al., CEN Case Rep 2013;2:158-164; Baschinsky et al., Am J Kidney Dis 2000;36:E24]. The most common association is between nephrotic syndrome and carcinoma [Baschinsky et al., Am J Kidney Dis 2000;36:E24]. We report a case of anti-neutrophil cytoplasmic antibody-negative crescentic glomerulonephritis associated with lung cancer. To the best of our knowledge, only 1 other case of ANCA-negative pauci-immune crescentic glomerulonephritis associated with lung cancer has been reported [Baschinsky et al., Am J Kidney Dis 2000;36:E24].
