Tumors with a significant oncocytic component include Warthin's tumor, oncocytoma, and oncocytic carcinoma.
Only a few isolated reports of Warthin's tumor of the nasopharynx have been published in the literature.
In a study of 278 cases of Warthin's tumor, Eveson and Cawson found that 13 (4.7%) were bilateral.
The cytologic findings suggested the presence of either an inflammatory process, Warthin's tumor, or a low-grade, mixed-cellularity, lymphoproliferative disorder.
Overall, cytology was definitive for a specific diagnosis in 13 of the 18 patients (72%): three cases of reactive lymph node, two cases each of lymph node metastasis and parotid Warthin's tumor, and in one case each of parotid pleomorphic adenoma, parotid adenoid-cystic carcinoma, parotid schwannoma-neurofibroma, parotid metastasis, parotid lymphoma, and Sjogren's-related reactive pleomorphic lymphoid-epithelial lesion.
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.
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).
Histological differential diagnoses include clear cell carcinoma, Warthin's tumor, mucoepidermoid carcinoma, and oncocytoma.
Mark et al., "The MECT1-MAML2 gene fusion and benign Warthin's tumor," Journal of Molecular Diagnostics, vol.
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].
In conclusion, we describe the eighth confirmed case in the literature of parotid oncocytoma in BHD, which mimicked Warthin's tumor on MR imaging.
Parotid swelling can result from a diverse spectrum of pathologies: inflammation or infections [e.g., bacterial, viral (e.g., mumps or HIV sialopathy), or chronic sialadenitis], autoimmune diseases (e.g., Sjogren's disease and chronic recurrent parotitis), granulomatous diseases (e.g., Wegener's granulomatosis and sarcoidosis), Kimura's disease, miscellaneous diseases (e.g., sialadenosis, polycystic disease, radiation sialadenitis, and pneumoparotid), neoplastic diseases (e.g., pleomorphic adenoma, Warthin's tumor, and mucosa-associated lymphoid tissue lymphoma), and pseudolesions (e.g., hypertrophy of the masseter muscle) (2).
