Coal worker / silicosis pneumoconiosis vs Asbestosis / berylliosis
How to tell Coal worker / silicosis pneumoconiosis and Asbestosis / berylliosis apart when a board question makes them look alike.
Coal/silica is upper-lobe nodular dust disease; asbestos is lower-lobe pleural-plaque fibrosis; beryllium is sarcoid-like occupational granulomas.
Side by side
Coal worker pneumoconiosis and silicosis usually produce upper-lobe nodular pneumoconiosis; silicosis can show egg-shell hilar node calcification and TB susceptibility.
Asbestosis causes lower-lobe fibrosis with pleural plaques and ferruginous bodies; berylliosis causes sarcoid-like noncaseating granulomatous disease after beryllium exposure.
Inhaled coal or silica dust is retained by macrophages and drives nodular fibrosis, sometimes progressing to massive fibrosis.
Asbestos fibers cause interstitial fibrosis and pleural disease; beryllium sensitization causes granulomatous immune lung disease.
Miner, sandblaster, quarry, or silica exposure with upper-lobe nodules points coal/silica pneumoconiosis; egg-shell calcification strongly supports silicosis.
Shipyard/construction asbestos exposure with pleural plaques points asbestosis; aerospace/electronics beryllium exposure with granulomas points berylliosis.
The trap
Occupational lung stems are solved by exposure plus lobe/pleura/granuloma pattern, not by “dust exposure” alone.
The repair move
For pneumoconiosis, name the job exposure, then check upper versus lower lobe, pleural plaques, and granulomas.

Show answer and explanation
Answer: A. Coal worker / silicosis pneumoconiosis. Coal worker pneumoconiosis and silicosis classically produce upper-lobe nodular pneumoconiosis and can progress to massive fibrosis.
Why the other choices are tempting
- B. Asbestosis is lower-lobe interstitial fibrosis with pleural plaques and asbestos bodies.
- C. Berylliosis is granulomatous disease from beryllium exposure.
- D. Panacinar emphysema is alpha-1 antitrypsin-related emphysema.
- E. Hypersensitivity pneumonitis is immune-mediated antigen exposure disease.
