A 79-year-old man was admitted to our hospital because of localized ground-glass opacification in the right upper lobe and a mass in the left lower lobe. We diagnosed autoimmune pulmonary alveolar proteinosis based on bronchoalveolar lavage and transbronchial lung biopsy findings from the right upper lobe, and the serum was positive for anti-granulocyte-macrophage colony-stimulating factor antibody. We diagnosed the left lower lobe mass as a lung adenocarcinoma by surgical biopsy because it could not be diagnosed by bronchoscopy. The present case showed localized pulmonary alveolar proteinosis with adenocarcinoma in the opposite lung, which is thought to be rare.
