Overview
There are 5 subtypes of silicosis that are differentiated according to the duration of exposure, development of symptoms, pulmonary function, and findings on chest imaging. Silicosis is classified as either simple chronic, complicated chronic, interstitial pulmonary fibrosis, accelerated silicosis, and acute silicosis.
Classification
There are 5 subtypes of silicosis that are differentiated according to the duration of exposure, development of symptoms, pulmonary function, and findings on chest imaging.[1][2][3]
| Subtype | Simple Chronic | Complicated Chronic | Interstitial Pulmonary Fibrosis | Accelerated Silicosis | Acute Silicosis |
| Duration of Exposure | Disease develops > 10 years following exposure to low - moderate concentrations of silica dust | Disease develops > 10 years following exposure to silica dust | Disease develops > 10 years following exposure to silica dust. | Disease develops 5 to 10 years following high exposure to silica dust | Disease develops within 5 years of exposure to extremely high concentrations of silica dust |
| Symptoms | Often asymptomatic | Dyspnea and cough | Dyspnea and cough | Dyspnea, weakness, and weight loss | Severe, disabling dyspnea, weakness, weight loss, and progressive respiratory failure |
| Pulmonary Function | May be normal or reduced | May be normal or reduced | May be normal or reduced | Reduced with rapid deterioration of FVC and FEV1 | Reduced with restrictive changes and reduced diffusion capacity |
| Imaging Findings | Nodules < 10 mm | Nodules > 1 cm with either obstructive or restrictive changes of variable severity | Diffuse reticulonodular pattern similar to idiopathic pulmonary fibrosis | Rapidly progressing nodules and masses | Bilateral perihilar acinar pattern consolidations with ground glass appearance |
