Abstract: Warthin’s tumor (WT), also known as papillary cystadenoma lymphomatosum, is a benign salivary gland neoplasm predominantly affecting the parotid gland. Despite its benign nature, the tumor presents unique diagnostic and clinical challenges due to its variable presentation and occasional multifocal or bilateral occurrence. The etiology of WT remains incompletely understood, though associations with smoking and lymphoid tissue interactions suggest a complex pathophysiology. Recent advancements in imaging and histopathological techniques have improved diagnostic accuracy, yet differentiating WT from other salivary gland neoplasms remains crucial for appropriate management. Surgical excision remains the primary treatment modality, particularly for symptomatic or enlarging lesions, although conservative management is increasingly considered in select cases. This review aims to provide an updated overview of the epidemiology, pathogenesis, diagnostic strategies, and treatment options for WT, emphasizing the role of modern imaging modalities and the emerging debate over the necessity of surgical intervention in all cases. Understanding the nuances of WT is essential for clinicians to ensure accurate diagnosis, optimize patient outcomes, and avoid overtreatment. Future research should focus on elucidating molecular markers for better risk stratification and exploring non-invasive management approaches.
