Abstract
ABSTRACT Warthin tumor is the second most common benign tumor of salivary glands. Here we present an interesting case of squamous cell carcinoma arising from the Warthin tumor in the cervical lymph node. The patient had another Warthin tumor in the parotid gland as well. Both the malignant transformation of Warthin tumor and the heterotopic occurrence of Warthin tumor in the cervical lymph node are rare. This exceptionally rare case demonstrates that the 2 rare clinical entities can occur simultaneously and affect clinical decisions.

Multifocal Warthin's Tumor: An Uncommon Presentation of Bilateral Cervical Lymphadenopathy. Case Rep Otolaryngol 2018; 2018:3791825. [PMID: 30254781 PMCID: PMC6140128 DOI: 10.1155/2018/3791825] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2018] [Accepted: 08/09/2018] [Indexed: 11/17/2022] Open
Abstract
Warthin's tumor is the second most common benign lesion of the parotid gland. It is most commonly encountered in male smokers in the fifth to seventh decades of life. Uniquely, among benign lesions of the parotid gland, it can be seen bilaterally in 7–10% of cases. Very rarely, Warthin's tumor can also mimic malignant or metastatic disease by presenting within cervical lymph nodes. We present a rare case of a 71-year old male smoker with bilateral parotid lesions in addition to progressively enlarging cervical and mediastinal lymphadenopathy. Excisional biopsy of a cervical lymph node ultimately revealed Warthin's tumor.

Abstract
Our aim was to define typical magnetic resonance (MRI) findings in malignant and benign parotid tumours. This study is based on retrospective evaluation of pre-surgical MRI of 94 patients with parotid gland tumours. Histology results were available for all tumours. There were 69 cases of benign (73%) and 25 cases of malignant (27%) tumours, including 44 pleomorphic adenomas, 18 Warthin's tumours, 7 various benign tumours, 6 squamous cell carcinomas, 3 carcinoma ex pleomorphic adenomas, 2 mucoepidermoid carcinomas, 1 adenoid cystic carcinoma and 13 various malignant tumours. The following MRI parameters were evaluated: shape, site, size, margins, signal intensity (SI) on T1w and T2w images, contrast enhancement, signal of cystic content, presence or absence of a capsule, perineural spread, extraglandular growth pattern and cervical adenopathy. Statistical analysis was performed to identify the MRI findings most suggestive of malignancy, and to define the most typical MRI pattern of the most common histologies. Ill-defined margins (p < 0.001), adenopathies (p < 0.001) and infiltrative grown pattern (p < 0.001) were significantly predictive of malignancy. Typical findings of pleomorphic adenoma included hyperintensity on T2w images (p = 0.02), strong contrast enhancement (p < 0.001) and lobulated shape (p = 0.04). Typical findings of Warthin's tumour included hyperintense components on T1w images (p < 0.001), location in the parotid inferior process (p < 0.001) and mild or incomplete contrast enhancement (p = 0.01). SI on T1w and T2w images and contrast enhancement enables differential diagnosis between pleomorphic adenoma and Warthin's tumour.

Abstract
BACKGROUND Warthin tumor is the second most common benign salivary gland neoplasm after pleomorphic adenoma. Warthin tumors occur almost exclusively in the parotid gland and periparotid lymph nodes, extraparotid localization is rare. METHODS AND RESULTS We describe a case of a patient presenting with a synchronous unilateral parotid gland and nasopharyngeal Warthin tumor. CONCLUSION We propose that, although this occurrence of a synchronous parotid gland and nasopharyngeal Warthin tumor may be coincidental, it is more likely to be an effect of a systemic factor.

Abstract
Introduction Warthin tumor is described as papillary cystadenoma lymphomatosum and is the second most common tumor of the parotid glands. Bilateral synchronous incidence is rare, occurring in 7 to 10% of the cases. It is more common in males between 60 and 70 years of age and is closely related to smoking. There is slow growth and the condition is a delimited nodule of regular outlines; it has low rates of malignant progression and recurrence. Objective Report a case of synchronous bilateral Warthin tumor occurring in an elderly patient, and review incidence and peculiarities of this tumor. Case Report A 78-year-old man who used to smoke had a history of mild pain in the topography of right parotid three weeks ago. Patient with hypertension, diabetes and a longtime smoker (smoking a pack per day for 32 years) noticed a progressive bulging in the right parotid region for about 2.5 years ago, and noticed another progressive bulging (althought in the left parotid region), for about one year ago. Patient denied fever, redness, skin lesions and pain during this period until last three weeks, when he sought medical attention for a mild pain in the right facial region. The patient underwent cervical magnetic resonance imaging that showed tumor lesions in both parotids. Fine needle aspiration revealed a typical lesion of epithelial oxyphilic cells associated with reactive lymphoid proliferation, suggesting Warthin tumor. The patient underwent two superficial parotidectomies, and the histopathologic result from both tumors of parotid glands showed papillary cystadenoma lymphomatosum. Conclusion The occurrence of synchronous bilateral Warthin tumor is extremely rare, and anamnesis and physical examination, as well as some complementary examinations, are important means for diagnostic evaluation. Confirmation of the diagnosis can only be obtained through a histopathologic study. A superficial or total parotidectomy is the recommended treatment for the disease.

Abstract
AbstractBackground:Warthin's tumours can show features of pseudo-neoplasia. They do not usually cause problems for diagnosis and management when present within the parotid gland. However, extraparotid Warthin's tumours that are associated with pseudo-neoplasia upon cytological analysis can mimic metastatic malignant disease. The case of a patient presenting with multifocal extraparotid Warthin's tumours is described.Case report:A 57-year-old male smoker presented with rapidly growing upper neck lumps. Fine needle aspiration cytology, magnetic resonance imaging and positron emission tomography findings were compatible with metastatic squamous cell carcinoma secondary to either an unknown primary upper aerodigestive or a parotid malignancy. The patient subsequently underwent total conservative parotidectomy and modified radical neck dissection. Final histology findings revealed multifocal benign Warthin's tumours with four extraparotid components.Conclusion:Warthin's tumours may present outside the parotid gland, present with multifocal lesions and mimic metastatic disease. Frozen section examination prior to radical resection should be considered to guide management.

Abstract
Warthin tumors (cystadenolymphoma, cystadenoma lymphomatosum papilliferum) account for approximately 10-15 % of all benign salivary gland tumors and are bilateral in approximately 10-15 %, as well as extraparotideal in approximately 8 % of cases. Nasopharyngeal Warthin tumors are extremely rare; however they should be borne in mind as a consideration of differential diagnostics. Furthermore, parotid glands and cervical lymph nodes should be examined as associated synchronous or metachronous manifestations are possible. Palpation, sonography and other radiological imaging of the cervical region, if applicable, might be required.

Abstract
AIM: To present computed tomography (CT) findings of different histological subtypes of parotid gland masses in detail and to establish diagnostic strategy.
METHODS: From January 2009 to November 2011, 56 patients were collected through the histopathology and Picture Archiving and Communication Systems records, which revealed 5 basal cell adenoma (BCA), 16 pleomorphic adenoma (PA), 25 Warthin’s tumor (War-T), 3 Kimura’s disease (KD) and 7 parotid carcinoma (PCa) cases. All the CT images were retrospectively analyzed by two radiologists in consensus, based on their description of morphology (location, number, size, margin and fibrous capsule) and enhancement patterns of masses. In addition, the diagnostic efficiency of diagnostic strategy is tested.
RESULTS: War-T and BCA patients’ mean age was 59.9 ± 12.6 years and 58.4 ± 18.2 years; the significant difference was seen in War-T vs PA and BCA vs PA. About 40% of War-Ts presented with bilateral multifocal lesions, a higher ratio than others. Seventy two percent of War-Ts were limited to the superficial lobe, followed by BCA 60% and PA 40%. Vessel facing sign and enlarged lymph nodes were both frequent in War-T, which respectively accounts for 84% and 76% of cases. Rapid contrast enhancement and decreases were unique for War-T. BCA and PA showed obvious delayed enhancement. The diagnostic strategy of parotid gland tumor had a good diagnostic efficiency, with high accuracy, sensitivity and specificity.
CONCLUSION: Determination of the histological subtypes of parotid gland masses might be possible based on CT findings and clinical data. A diagnostic strategy with high diagnostic efficiency was established.

The association of warthin tumor with salivary ductal inclusions in intra and periparotid lymph nodes. Head Neck Pathol 2013; 8:73-6.

Abstract
A predominant theory of the much debated histogenesis of Warthin tumor (WT) is that it arises from heterotopic salivary ductal inclusions (SDI) in parotid lymph nodes (LN). If this were the case, we might expect to see an increased number of SDI in the lymph nodes of patients with WT compared to controls. To test this, we compared the prevalence of SDI in patients with WT versus those with pleomorphic adenoma (PA). Cases of WT and PA were retrieved from the case files of the Department of Pathology at the QEII Health Science Centre, Halifax, NS, Canada. We then compared the prevalence of SDI in parotid LN between patients diagnosed with WT versus PA. 46 WT and 52 PA met our inclusion criteria. WT was significantly associated with an older age at surgery (62.5 years vs 50.2 years, p = 0.001). 71.7 % of WT and 32.7 % of PA had inclusions in any LN. The presence of inclusion is a significant predictor for WT versus PA (p = 0.019). Where smoking status was available, 92.5 % of WT patients were smokers/ex-smokers, versus. 55.1 % of PA (p = 0.034 for current smokers). Among PA, 44 % of smokers had inclusions compared with 22.7 % of non-smokers. SDIs are more frequent in parotid LN from patients with WT than PA. The high proportion of smokers among WT patients is consistent with prior studies. The results support the hypothesis that WT arises from SDIs. Individuals with more SDIs may be predisposed to WT.
