Micrograph of asbestosis showing the characteristic ferruginous bodies and marked interstitial fibrosis (or scarring). H&E stain. Close-up asbestosis right lower zone ILO 2/2 S/S Lateral chest X-ray in asbestosis shows plaquing of the diaphragm. According to the American Thoracic Society (ATS), the general diagnostic criteria for asbestosis are ...
Asbestos-related diseases are disorders of the lung and pleura caused by the inhalation of asbestos fibres. Asbestos-related diseases include non-malignant disorders such as asbestosis (pulmonary fibrosis due to asbestos), diffuse pleural thickening, pleural plaques, pleural effusion, rounded atelectasis and malignancies such as lung cancer and malignant mesothelioma.
Ferruginous bodies.H&E stain.. A ferruginous body is a histopathologic finding in interstitial lung disease suggestive of significant asbestos exposure ().Asbestos exposure is associated with occupations such as shipbuilding, roofing, plumbing, and construction.
The first known U.S. workers' compensation claim for asbestos disease was in 1927. In 1930, the first reported autopsy of a person with asbestosis was conducted in the United States and later presented by a doctor at the Mayo Clinic, although in this case the exposure involved mining activities somewhere in South America.

In 1974, after studies of surveillance programs for coal miners revealed unacceptable degrees of reader variability, [1] NIOSH began the "B" reader program (so named because of the Black lung or Coal Workers' X-ray Surveillance Program), with the intent to train and certify physicians in the ILO Classification system [2] (for classifying radiographs for the presence of pneumoconiosis), so as ...
Pneumoconiosis is a classification of interstitial lung disease caused by inhalation and accumulation of airborne particles in the lungs. [2] Coal worker's pneumoconiosis, asbestosis, and silicosis are common forms of pneumoconiosis that have been shown to cause interstitial pulmonary fibrosis which, in advanced stages, may be observed as "honeycombing" on CT imaging.
The X-ray may reveal pleural thickening commonly seen after asbestos exposure and increases suspicion of mesothelioma. [15] A CT (or CAT) scan or an MRI is usually performed. If a large amount of fluid is present, abnormal cells may be detected by cytopathology if this fluid is aspirated with a syringe. [ 11 ]
Asbestos (/ æ s ˈ b ɛ s t ə s, æ z-,-t ɒ s / ass-BES-təs, az-, -toss) [1] is a group of naturally occurring, toxic, carcinogenic and fibrous silicate minerals.There are six types, all of which are composed of long and thin fibrous crystals, each fibre (particulate with length substantially greater than width) [2] being composed of many microscopic "fibrils" that can be released into ...
