✦ Synopsis

Synchronous parotid neoplasms are rare. Unilateral, synchronous neoplasms of two separate and histologically distinct types are extremely unusual. Our review of the literature revealed 31 previously reported cases. We add two additional cases found in 291 parotid neoplasms seen in our institutions over the last 10 years; both including a pleomorphic adenoma and a Warthin's tumor. This combination was found in 15 of 33 cases, while Warthin's tumors were found in association with another tumor in 24 of 33 reported cases (82%). HEAD & NECK 11 ~179-183.1989 Salivary gland neoplasms account for 3% of head and neck neoplasms. The vast majority of salivary gland neoplasms occur in the parotid and 80% of these are benign.',' Most studies reveal that 50%-80% of these benign neoplasms are pleomorphic adenomas (mixed tumors)'-3 and 5%-20% are Warthin's tumors (papilary cystadenoma lymphomatosum or adenolympho-Synchronous parotid neoplasms are rare. Turnbull and Frazel17 found bilateral tumors in 1.4% of their 1,837 patients with parotid neoplasms. Bilateral neoplasms usually involve
