Risk calculators and risk factors for Warthin's tumor

Overview

Warthin's tumor is a type of benign tumor of the salivary glands. It is also known as benign papillary cystadenoma lymphomatosum. Its etiology is unknown, but there is a strong association with cigarette smoking. Smokers are at 8 times greater risk of developing Warthin's tumor than the general population.

Epdidemiology and Demographics

The gland most likely affected is the parotid gland. Though much less likely to occur than pleomorphic adenoma, Warthin's tumor is the second most common benign parotid tumor. Warthin's tumor is more likely to occur in older adults between 60 -70 years of age. There is a slight female predilection according to recent studies, but historically it has been associated with a strong male predilection. This change is possibly due to the tumor's association with cigarette smoking and the growing use of cigarettes in women.

Pathophysiology

The appearance of this tumor under the microscope is unique. There are cystic spaces surrounded by two uniform rows of cells with centrally placed pyknotic nuclei. The cystic spaces have epithelium referred to as papillary infoldings that protude into them. Additionally, the epithelium has lymphoid stroma with germinal center formation.

Diagnosis

Symptoms

The tumor is slow growing and painless.

Physical Examination

The tumor usually appears in the tail of the parotid gland near the angle of the mandible. In 5 - 14% of cases, Warthin's tumor is bilateral, but the two masses usually are at different times.

Treatment

Most of these tumors are treated with surgical removal. Recurrence is rare, occurring in 6 - 12% of cases. Warthin's tumor is highly unlikely to become malignant.
