Artificial stone-associated silicosis: clinical-pathological-radiological correlates of disease (vol 7, e00470, 2019)

Occupational lung disease secondary to inhalation of silica particles is variable and potentially life-threatening. As the artificial stone industry has grown over the last two decades, the development of silicosis has been seen to accelerate and behave differently to chronic silicosis. In this case report, we present two patients who underwent lung transplantation for silicosis at the Alfred Hospital, both with predominantly artificial stone masonry exposure. We have identified the presence of both fibrotic/nodular silicosis and conspicuous alveolar proteinosis within the same lung parenchyma of both patients. We then demonstrate the radiological and histopathological correlates of disease; the first time this has been shown clearly in the literature.
