Of parotid tumors, 80%-85% are benign, most of which are pleomorphic adenoma (PA) and Warthin tumor (WT) (1).
Abbreviations: c/w, consistent with; LOUS, lesion of unknown significance; Neg, negative; PA, pleomorphic adenoma; Pos, positive; Susp, suspicious; Unsat, unsatisfactory; WT, Warthin tumor.
Thus, a benign parotid gland tumor such as Warthin tumor or pleomorphic adenoma was suspected preoperatively.
Bullock, "The association of warthin tumor with salivary ductal inclusions in intra and periparotid lymph nodes," Head and Neck Pathology, vol.
reported a patient who had sebaceous lymphadenoma of parotid gland which was well circumscribed but appeared to be multiloculated cystic in MRI and made them think it is a Warthin tumor [7].
Out of 12 cases reported as Warthin tumor, the majority involved parotid gland (N=9; 15%) followed by submandibular gland (N=3; 5%).
This study also found a remarkably high risk for Warthin tumor with OR of 15.3 (95% CI: 6.1-38.5) for ever-cigarette smoker, an increased risk for malignant tumors (OR = 1.69, 95% CI: 0.81-3.51), and no association for pleomorphic adenoma (OR = 1.01, 95% CI: 0.75-1.37).
Benign lesions other than pleomorphic adenoma and Warthin tumor included oncocytic adenomas, lipomas, lipomatosis, basal cell adenoma, nonsebaceous lymphadenoma, branchiogenic cyst, and chronic inflammation.
Type of benign tumor were; pleomorphic adenoma, monomorphic adenoma, warthin tumor, myoepithelioma and hemangioma.
We conducted a retrospective study to assess the accuracy of fine-needle aspiration cytology (FNAC) in the diagnosis of Warthin tumor and to evaluate the subsequent risk of conservative nonsurgical management.
The coexistence of a Warthin tumor composed of cystic spaces lined by papillary bilayered oncocytic epithelium was also observed (Fig.
