What demographic is predominantly associated with Warthin tumor?

Warthin tumor, also known as papillary cystadenoma lymphomatosum, is predominantly associated with older men, particularly those with a history of smoking. This benign salivary gland tumor typically occurs in the parotid gland and has a unique epidemiological profile. The association of Warthin tumor with older age groups, particularly men, suggests a potential link between hormonal factors and the development of this tumor. The history of smoking further heightens the risk, as cigarette smoke comprises numerous carcinogens that may contribute to the tumor's development.

Understanding the demographics is crucial, as it helps in the clinical evaluation and management of patients presenting with symptoms that may suggest a salivary gland tumor. Other demographics listed, such as young adults or children and adolescents, are not typically associated with Warthin tumors, making it clear why the correct answer focuses on older men with a background of smoking.
