To describe exposures to talcum powder leading to mesothelioma among 33 individuals as a non-occupational asbestos exposure.
Cases were referred for medico-legal evaluation, and tissue digestions were performed in some cases. Tissue digestion for the six cases described was done according to standard methodology
Asbestos of the type found in talcum powder was found in all six cases evaluated.. Talcum powder usage was the only source of asbestos for all 33 cases.
Exposure to asbestos-contaminated talcum powders can cause mesothelioma. Clinicians should elicit a history of talcum powder usage in all patients presenting with mesothelioma.

Clinical Significance: This manuscript is the first to describe mesothelioma among talcum powder consumers. Our case study suggest that cosmetic talcum powder use may help explain the high prevalence of idiopathic mesothelioma cases, particularly among women, and stresses the need for improved exposure history elicitation among physicians.
