Large and multiple Warthin's tumors of bilateral parotid glands: A case report of bilateral regional excision of the parotid

Large, bilateral Warthin's tumor of the parotid gland is clinically very rare. Histologically, Warthin's tumor is related to lymphoid tissue. Its onset may be multiple, but it does not grow aggressively. In our patient, it did not invade the facial nerve. We described a case of large, bilateral, multiple Warthin's tumors of the parotid glands. Clinically, the patient had no pain; the main manifestation was a swelling of the parotid region. The swellings were so large that they affected the patient's quality of life. The patient had been smoking 20 cigarettes a day for 30 years. We performed a bilateral, regional resection of the parotid glands. This procedure prevents tumor recurrence while retaining the parotid duct and major functions of the parotid gland. Warthin's tumor may have a history of remissions and no pain, thus not easily attracting the patient's attention. We believe that asymptomatic tumors should arouse people's attention, enabling them to get early treatment and improving their quality of life. In the resection of parotid benign tumor, the preservation of facial nerve is still the focus of attention.
