Occupational lung diseases are occupational or work related lung conditions that have been caused or made worse by the materials a person is exposed to within the workplaceIt includes a broad group of diseases including occupational asthma chronic obstructive pulmonary disease COPD bronchiolitis obliterans inhalation injury interstitial lung diseases such as pneumoconiosis Some of the ILDs are more common in certain age groups For example the majority of patients with sarcoidosis connective tissue disease associated ILD lymphangioleiomyomatosis pulmonary Langerhans cell histiocytosis inherited forms of ILD familial IPF Gaucher s disease Hermansky Pudlak syndrome present between the ages of 20 and 40 years
