title: Synchronous parotid and nasopharyngeal Warthin's tumors: first report of a case.
abstract: Only a few isolated reports of Warthin's tumor of the nasopharynx have been published in the literature. None of the patients cited in those reports had another Warthin's tumor elsewhere. We describe the case of a patient who had synchronous nasopharyngeal and parotid Warthin's tumors--a case that we believe is the first to be reported in the literature. Our case provided us with a unique opportunity to study and compare the two tumors in a single patient. Their simultaneous presence might have been more than coincidental; it is possible that these two tumors were the result of the influence of one or more unknown systemic factors on trapped salivary elements in the lymphoid stroma.
