Esophageal Carcinoma Presenting with Nephrotic Syndrome: Association with Anti-Neutrophil Cytoplasmic Antibody.

Malignancy is a cause of membranous glomerulonephritis. We report a patient with an otherwise asymptomatic squamous cell carcinoma of the esophagus whose presenting manifestation was membranous glomerulonephritis and nephrotic syndrome. Perinuclear antineutrophil cytoplasmie antibody was positive. This is the first reported case of perinuclear anti-neutrophil cytopiasmic antibody associated with paraneoplastic glo-nierulonephritis and nephrotic syndrome due to esophageal squamous cell carcinoma.
