Pulmonary alveolar proteinosis
MONDO:0001437A rare lung disorder characterized by the filling of the pulmonary alveoli with proteinaceous material which stains positive with periodic acid-Schiff stain. It may be idiopathic or secondary due to hematologic malignancies or the inhalation of mineral dusts. Signs and symptoms include dyspnea, cough and low grade fever.
Also known as: PAP, pulmonary alveolar proteinosis
