Second primary tumor associated with salivary gland cancer.

That patients with salivary gland cancer are at increased risk of second primary tumors has been suggested in several studies. This report presents the case of a 53-year-old woman with an epithelial-myoepithelial carcinoma of intercalated duct origin occurring in the parotid gland synchronously with a follicular cell carcinoma of the thyroid gland. This is believed to be the first report of such an association.
