Recently, a number of reports have been published on silicosis in workers exposed to artificial quartz conglomerates containing high levels of crystalline silica particles (70-90%) used in the construction of kitchen and bathroom surfaces. Three cases of silicosis in workers exposed to artificial quartz conglomerates are reported. The diagnosis was derived from both the International Labour Office and the International Classification of HRCT for Occupational and Environmental Respiratory Diseases (ICOERD) classifications and cytological analysis of bronchoalveolar lavage fluid. In 2 cases, levels of respirable silica greatly in excess of recommended standards were measured in the workplace, and cytological analysis of bronchoalveolar lavage fluid highlighted a prevalence of lymphocytes, meeting criteria for the diagnosis of accelerated silicosis. The prevention of pneumoconiosis caused by the use of innovative materials, such as artificial conglomerates with high crystalline silica content must be addressed.
