Etymed
silicosis
Definition
A chronic lung disease caused by inhaling silica dust, characterized by inflammation and scarring of lung tissue
Clinical context
A 45-year-old construction worker presents with progressive dyspnea and a persistent dry cough over several years. He works with sandblasting equipment daily and has noticed his exercise tolerance has significantly decreased. Chest X-ray reveals bilateral pulmonary nodules and increased bronchovascular markings. His symptoms worsen with exposure to dusty environments. The most likely diagnosis is silicosis from occupational silica exposure.
