Restrictive lung disease caused by prolonged exposure to asbestosis fibers; associated with a high incidence of malignant lung tumors and pleural abnormalities.
Any group of acquired disorders that have in common diffuse immunologic and inflammatory changes in small blood vessels and connective tissue. The cause of most of these diseases is unknown. Also called collagen vascular disease.
Connective Tissue Disease
Chemical or biological substance that is lethal to living cells.
No known physiologic, radiographic, or pathologic pattern. Diagnosis is usually made when a patient with this disease is exposed to a medication known to result in lung disease, the timing of the exposure is appropriate for the development of the disease, and other causes of this disease have been eliminated.
Inflammatory form of interstitial pneumonia that results from an immunologic reaction in a hypersensitive person. The reaction may be provoked by a variety of inhaled organic dusts, often those containing fungal spores. The disease can be prevented by avoiding contact with the causative agents. Also called extrinsic allergic alveolitis.
Hypersensitivity Pneumoitis (HP)
Formation of scar tissue in connective tissue of the lungs without known cause
Idiopathic pulmonary fibrosis
Respiratory disorder characterized by a dry, unproductive cough and dyspnea on exertion, X-ray films usually show fibrotic infiltrates in the lung tissue, usually in the lower lobes.
Interstitial Lung Disease (ILD)
Lung abnormally most commonly observed in women characterized by abnormal proliferation of smooth muscle cells in the interstitum and characterized by dyspnea, abnormal radiographic findings, and commonly pneumothorax
Interstitial lung disease due to an occupation exposure, of which asbestosis is a common example
Condition characterized by abnormal proliferation of Langerhans cells, accompanied by interstitial marking on the chest film and dyspnea
Pulmonary Langehan's Cell Histiocytosis (PLCH)
Chronic disorder of unknown origin characterized by the formation of tubercles of non-necrotizing epitheloid tissue
Lung disorder caused by continued, long-term exposure to the dust of an inorganic compound, silicon dioxide, which is found in sands, quartzes, and in many other stones; chronic silicosis is marked by widespread fibrotic nodular lesion in both lungs
