Hardmetal Disease
The association between parenchymal lung disease and hardmetal exposure was first observed in Germany and several later reports exist from other countries. An extensive summary of the related literature in regard to clinical surveys, epidemiological studies, clinical presentation, pathology, and hypotheses on pathogenesis was presented recently by D. Lison and co-workers [14.6,14.7].
