A BSTRACT Pulmonary alveolar proteinosis (PAP) is an uncommon condition make distinctive presence of granular eosinophilic material within alveolar spaces. PAP is also known as pulmonary alveolar lipoproteinosis, showing abundant lipids within granular exudate. Bronchoalveolar lavage (BAL) is helpful in both terms of therapeutic, as well as diagnostic point of view. Whole lung lavage given in patients of PAP feel dramatically better with improvement in exertional dyspnoea.
