Unusual occupationally related disorders of the lung: case reports and a literature review.

Diseases of the lung are among the work-related conditions most widely recognized among nonspecialists and the lay public. Five pulmonary conditions for which occupational or environmental exposures are not typically emphasized are reviewed here in their clinical-pathologic context. These are diffuse alveolar hemorrhage, lipoid pneumonitis, granulomatous lung disease, pulmonary alveolar proteinosis, and pulmonary vascular disease.
