Simultaneously occurring salivary gland tumors of different types

Two cases of simultaneously occurring salivary gland tumors of the parotid gland are reported. Both patients were women in the sixth decade of life. In the first patient, a carcinoma in pleomorphic adenoma and an oncocytoma were found in the right parotid gland. The second patient had an adenoid cystic carcinoma associated with a sebaceous cell adenoma. The addition of these cases to the previously published data brings the total number of simultaneously occurring salivary gland tumors of different types to ten.
