Art glassware and sinonasal cancer: report of three cases.

In a multicenter study on the occupational etiology of sinonasal cancer (s.n.c.) carried out in Italy, we collected information about three cases which had arisen among glass workers: an adenocarcinoma, a melanoma, and a squamocellular carcinoma. The three men worked many years as mixers and/or batchers in artistic glass factories in Tuscany (Italy). We propose a possible etiological role of arsenic dust.
