Abstract

A raised serum level of KL-6 is known to exist in active pulmonary fibrosis and KL-6 may be produced and secreted by type II pneumocytes. A case is described of pulmonary alveolar proteinosis with high serum KL-6 levels. The serum KL-6 level decreased after whole lung washing and correlated with symptoms, opacities on the chest radiograph, and arterial blood gas measurements. The serum KL-6 level may represent a useful marker for pulmonary alveolar proteinosis.
