Sebaceous Lymphadenoma: Radiology-Pathology Correlation

Sebaceous lymphadenoma is a rare salivary gland neoplasm most commonly occurring in the sixth to eighth decades of life. Cross sectional imaging typically demonstrates a multicystic expansile mass, most commonly occurring in the parotid gland, where the radiographic differential diagnosis would include Warthin tumor in this location and age group. Ultimately, the diagnosis is confirmed with the histopathologic findings of tubuloglandular epithelial profiles with sebaceous differentiation and cystic change set within a dense, benign lymphocytic infiltrate. These features are exemplified in this sine qua non radiology-pathology correlation article.
