A 51-year-old man with Behçet’s disease complained of fever, dry cough and dyspnea during exertion. Chest CT showed ground glass opacities with interstitial septal thickening in both lungs. Bronchoalveolar lavage (BAL) revealed amorphous and lipoproteinaceous material that was periodic acid-Schiff (PAS) stain positive. Transbronchial biopsy specimen demonstrated PAS positive alveolar eosinophil...

Pulmonary alveolar proteinosis (PAP) is a rare and diffuse lung process, characterized by the presence of alveolar spaces filled with amorphous eosinophilic material. Impaired macrophage function and impaired host defence due to abnormalities of surfactant proteins may favor the growth of microorganisms. The association of alveolar proteinosis with mycobacterial infections is rarely reported. T...

  Silicosis is considered to be among the occupational lung diseases and associated with sandblasting, mining, quarrying and tunneling. Acute silicosis is usually progressive diseaseand despite treatment with corticosteroids it leads to cardio-respiratory failure and death. Alveolar silicoproteinosis is one of it’s acute presentations due to exposure to silica dust and lungs filling with protei...

Pulmonary alveolar proteinosis (PAP) is a rare disease in which surfactant accumulates abnormally in the pulmonary alveolar walls and causes respiratory symptoms. The only known effective treatment for PAP is pulmonary lavage. We have reported an 11year-old girl with pulmonary alveolar proteinosis who underwent pulmonary lavage with normal saline under general anesthesia by a new method (using ...

Pulmonary alveolar proteinosis (PAP) is a rare disorder characterised histologically by an intra-alveolar accumulation of fine granular eosinophilic and periodic acid-Schiff positive material. In a retrospective study, the composition of the intra-alveolarly accumulated material of adult patients with PAP was analysed by means of immunohistochemistry and Western blotting. In patients with PAP, ...
