Accelerated silicosis is similar to chronic silicosis but develops more rapidly in patients with high levels of exposure, with onset of disease within 5 to 10 years after initial exposure. Progressive massive fibrosis (PMF, or conglomerate or complicated silicosis) is the advanced form of chronic or accelerated silicosis.

Silicosis was described radiologically in 73.3% of our patients (44 of 60 patients). Our detection rate is higher than that reported by Akgun et al. who detected silicosis in 53% of patients (77 of 145 patients) using chest X-ray. The patients in their study were of a similar age, but had a longer latency period and duration of exposure to ...

Silicosis. Silicosis is caused by inhalation of unbound (free) crystalline silica dust and is characterized by nodular pulmonary fibrosis. Chronic silicosis initially causes no symptoms or only mild dyspnea but over years can advance to involve most of the lung and cause dyspnea, hypoxemia, pulmonary hypertension, and respiratory impairment.

Silicosis is the oldest known environmental lung disease . It is caused by inhalation of tiny particles of the mineral silica (usually quartz) or, less commonly, by inhalation of silicates, such as talc.

Chronic silicosis results from long-term exposure (more than 20 years) to low amounts of silica dust. The silica dust causes swelling in the lungs and chest lymph nodes. This disease may cause people to have trouble breathing. This is the most common form of silicosis. Accelerated silicosis occurs after exposure to larger amounts of silica over ...
