Although the clinico-pathologic features presented are apparently different, silicosis and asbestosis are both interstitial lung diseases caused by chronic exposure to airborne inorganic dusts, and the pathology of these two diseases is essentially a fibrosis. However, elucidation of silica-induced inflammation cascades and inflammation-fibrosis relations has uncovered several novel possibilities of therapeutic targeting. 97 Silicosis - Pulmonary Disorders - Merck Manuals Professional Edition The AUC for silicosis diagnosis was 0.716 (95% CI; 0.664 - 0.767), whereas for the identification of complicated silicosis it was 0.635 (95% CI; 0.582-0.688). Silicosis is caused by inhalation of unbound (free) crystalline silica dust and is characterized by nodular pulmonary fibrosis. The macrophage plays a key role in silicosis pathophysiology. As the scarring continues to worsen, the first real signs of a problem may be an abnormal chest X-ray and a slowly developing cough.
