Based on type, the parotid tumors market is segmented into cancerous/malignant tumor, pleomorphic adenoma, and Warthin's tumor.
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.
Many morphological variants of this tumour have been described based on various characteristics like size (micro papillary carcinoma), circumscription (encapsulated variant), architecture (classical, follicular, solid, micro papillary, Warthin like) and based on the cell size and type (columnar, tall cell).
Thus, a benign parotid gland tumor such as Warthin tumor or pleomorphic adenoma was suspected preoperatively.
Considerations include focal presentation of Sjogren syndrome, lymphoepithelial cysts, first branchial cleft cyst, Warthin's tumor, acinic cell carcinoma, mucoepidermoid carcinoma, salivary duct carcinoma, and metastatic thyroid papillary carcinoma.
It's unclear how serious his injuries were, Morgan Warthin, spokeswoman for the park, (https://q13fox.com/2018/08/23/bear-attack-injures-10-year-old-washington-boy-in-yellowstone-park/) reportedly said .
Histological differential diagnoses include clear cell carcinoma, Warthin's tumor, mucoepidermoid carcinoma, and oncocytoma.
While unilateral parotid growth is often seen in the presence of bacterial infections, chronic sialadenitis, duct obstruction, and neoplastic diseases (such as lymphoma and Warthin's tumor), bilateral growth is expected in the case of masseter muscle hypertrophy, viral infections (such as mumps and HIV), SjS, amyloidosis, sarcoidosis, acromegaly, anorexia, and alcoholism (3-5).
Oncocytic metaplasia is a feature of Warthin's tumour and may also be a component of malignant salivary gland tumours like mucoepidermoid carcinoma, acinic cell carcinoma, pleomorphic adenoma, and oncocytic myoepithelioma [3].
Warthin's tumor (WT), also known as papillary cystadenoma lymphomatomsum, is the second most common benign salivary gland neoplasm representing between 6 and 10% of cases [1, 2].
The lesion was suspected to be Warthin's tumor, and a right superficial parotidectomy was performed accordingly.
