title: Chronic lymphocytic pulmonary infiltrate and Bence-Jones proteinuria.
abstract: The clinical and radiological features in a 79-year-old patient with a chronic lymphocytic pulmonary infiltrate are described. The associated findings of Bence-Jones proteinuria, paraprotein bands in the plasma and a monoclonal population of circulating lymphocytes are strong evidence for a pulmonary lymphocytic lymphoma. The differential diagnosis is discussed.
