Abstract
Malignant mesothelioma is a rare malignancy of serosal-lined tissues. It has been recognized since the last century that the majority of pleural mesotheliomas are caused by exposures to asbestos, a fibrous silicate mineral that was used extensively in the construction trades for its insulating properties. A previously unrecognized source of asbestos exposure is cosmetic talc that has been widely used for personal hygiene and other purposes by adults and children. Since 2014, more than 200 cases of mesothelioma have been reported in individuals, whose only known source of asbestos exposure was cosmetic talc. In this chapter the association of talc with malignant mesothelioma will be reviewed.
