Beryllium and other metal-induced lung disease.

PURPOSE OF REVIEW

Metals can cause disease of the upper and lower respiratory tract that mirror disease due to other causes, such as asthma, rhinosinusitis, acute bronchitis, chronic bronchitis, acute pneumonitis, bronchogenic carcinoma, and interstitial lung disease. This article will describe some uncommon and unique lung diseases that can be induced by metals.

RECENT FINDINGS

Our understanding of old occupational lung diseases, such as chronic beryllium disease, continues to increase. New exposures in the workplace, such as indium, have been identified as novel occupational hazards. New forms of exposure, such as titanium dioxide nanoparticles, create risk of lung disease that is not seen with larger particles.

SUMMARY

Knowledge of several unusual and/or unique occupational lung diseases should prompt questioning about a patient's occupational history, which may uncover an occupational, rather than an idiopathic, lung disease.
