46-Year-Old Man with Bilateral Metachronous Pleomorphic Adenoma of the Parotid Gland
The occurrence of multiple distinct tumors in major salivary glands is quite rare. Although the most common tumor with bilateral synchronous or metachronous development is Warthin’s tumor, on rare occasions, pleomorphic adenomas have been diagnosed simultaneously as well. In this paper, we present the case of a 46-year-old man with bilateral metachronous pleomorphic adenoma of the parotid gland.
