INTRODUCTION: Paraneoplastic nephrotic syndrome associated with malignant broncho-pulmonary tumors. Three cases and literature review. Malignant broncho-pulmonary tumours are the principal cause of a paraneoplastic nephrotic syndrome. These tumours are most often small cell or squamous bronchial carcinomas. In 75% of cases the nephrotic syndrome is due to a membranous glomerulonephritis and it usually precedes the discovery of the causative tumour. CASES REPORT: Three cases of paraneoploastic nephrotic syndrome associated with bronchial carcinoma are described. The first is of a bronchial carcinoid tumour associated with a membrano-proliferative glomerulonephritis. In the second a bronchial adenocarcinoma was revealed by a membranous glomerulonephritis. The last case concerns a squamous carcinoma associated with a nephrotic syndrome in which the histological lesions were not documented on account of progression to rapidly fatal acute renal failure. CONCLUSION: A revue of the literature describes the associations between paraneoplastic nephrotic syndrome and bronchial carcinoma.
