Silicosis

Silicosis is interstitial pulmonary fibrosis from inhalation of crystalline silica dust (mining/sandblasting/stone cutting), presenting with progressive dyspnea, cough, upper-lobe nodular opacities, eggshell calcification of hilar nodes, and risk of TB/lung cancer. Types: acute, accelerated, chronic. Treatment: avoid further exposure; supportive care; oxygen for hypoxemia; pulmonary rehab; treat TB (high risk); treat infection/complications; surveillance for lung cancer; no proven antifibrotic; smoking cessation.

Common Symptoms

Progressive dyspnea/cough; upper-lobe nodules; eggshell hilar calcification; silica exposure; risk of TB/cancer

Causes and Pathogenesis

Silica particles cause alveolar macrophage inflammation and fibrotic nodule formation.

Treatment

Avoid exposure; supportive; oxygen/rehab; treat TB; cancer surveillance

Preventive Measures

Occupational dust control; TB screening; smoking cessation.

Department to Visit
