PAP
Pulmonary alveolar proteinosis (PAP) is a rare disease of unknown cause. It is characterized by the deposition of insoluble phospholipid-rich proteins in the alveoli, and the main clinical symptoms are shortness of breath, cough and sputum. Chest X-ray shows diffuse pulmonary infiltration shadows in both lungs. Pathological examination is characterized by alveoli filled with protein-like substances that are positive for periodic acid-Schiff (PAS) staining. The disease was first reported by Rosen in 1958. Pulmonary alveolar proteinosis can be divided into primary, secondary and congenital according to the cause.
