Idiopathic pulmonary alveolar proteinosis is presumed to be an autoimmune disorder that may lead to pulmonary insufficiency. However, steroids do not appear to be effective and the standard of therapy is whole-lung lavage. We report the first case of successful therapy with rituximab, which addresses the pathogenic mechanism of pulmonary alveolar proteinosis.
