Description
Cytologic smears of a Warthin's tumor (WT) typically consist of sheets of oncocytic (oxyphilic) cells and scattered lymphocytes. Reparative foci within this neoplasm can occur, which may give rise to exfoliated, malignant‐appearing, squamouslike cells. A false‐positive diagnosis of squamous carcinoma can occur when these atypical cells dominate the cytologic aspirate. Histochemical and immunoperoxidase stains may aid in diagnosing an atypical WT when the usual cytologic features are absent.
