Abstract PDF: Lymphangioleiomyomatosis (LAM) is a rare, cystic lung disease that is associated with mutation in the tuberous sclerosis genes, renal angiomyolipomas, lymphatic spread and a remarkable female gender predilection. The pathology of LAM is represented by the proliferation of immature smooth muscle cells in the walls of airways, and venules and lymphatic vessels in the lung. The clinical course of LAM is characterized by progressive dyspnea on exertion, recurrent pneumothorax and collections of chylous fluid. The diagnosis of pulmonary LAM can be made on chest X-ray, a high-resolution CT scan and lung biopsy. We experienced a case of pulmonary lymphangioleiomyomatosis in a 28-years-old female patient who had suffered from progressive dyspnea on exertion, so we report on it along with a brief review of the relevant literature.

Pulmonary alveolar proteinosis (PAP) is a rare disorder that's characterized by accumulation of surfactant components in the alveolar space. Idiopathic PAP is recognized as an autoimmune disease that's due to impaired alveolar macrophage function and this caused by autoantibodies against granulocyte-macrophage colony-stimulating factor (GM-CSF). We report here a case of pulmonary alveolar proteinosis that was deemed interstitial lung disease at the initial diagnosis. A 61-year-old man presented with intermittent blood tinged sputum and dyspnea on exertion. The man was a painter for 30 years and he had a 10 pack-years smoking history. Chest computerized tomography (CT) revealed multifocal ground-glass opacity with interstitial thickening at both lungs. His pulmonary function tests and methacholine test revealed non specific results. He was diagnosed with interstitial lung disease on the basis of the chest CT finding and occupational history. However, seven months later, his symptoms progressed. Follow-up chest CT was performed. Wedge resection via video-assisted thoracoscopic surgery (the anterior basal segment of the left lower lobe) was done. Microscopic examination showed large groups of alveoli with excessive amounts of surfactant and a complex mixture of protein and lipid (fat) molecules. Finally, he was diagnosed as having pulmonary alveolar proteinosis.
