Tumor cells are less responsive to these restraints and can proliferate to the point where they disrupt tissue architecture, distort the flow of nutrients, and otherwise do damage. Tumors may be benign or malignant. Benign tumors remain localized as a discrete mass. They may differ appreciably ...
This pattern is often associated with Warthin tumor; however, other benign and malignant entities fall under this diagnostic group. Epithelioid cell clusters with an extensive lymphoid background: a common cytologic architectural pattern in the diagnosis of salivary gland lesions by fine-needle aspiration...
It has been reported in the literature that WT are positive on positron emission tomography (PET) scan, and therefore may be easily misdiagnosed as metastases or primary malignant salivary gland tumors. Fine-needle aspiration biopsy is frequently used to investigate and distinguish between benign and...

Concurrent Warthin tumor and Kimura disease: a case report Asma Almazyad1,2,3* , Naheel Al Khudiri1, Saeed S. Alshieban1,2,3 and Majed M. Pharaon2,3 Abstract Background Warthin tumor (WT) is a common benign salivary tumor of the parotid ...
Warthin tumor, also known as papillary cystadenoma lymphomatosum, is a fairly common tumor. It makes up 14% to 30% of parotid tumors. There has been much interest in this tumor because of its typical and intriguing morphologic features: the association of benign-looking lymphoid and epithelial...
Warthin tumor (papillary cystadenoma lymphomatosum) is a benign salivary gland tumor that occurs almost exclusively in the parotid gland. As far as we know, only 15 cases of laryngeal Warthin tumor have been previously reported worldwide. We describe the case of a 75-year-old woman with a ...
Warthin's tumour is the second most common benign neoplasm to affect the salivary glands. It virtually affects the sole parotid gland. A sudden increase in a tumour's size is usually due to a malignant transformation of the tumour. The t... F Allevi,F Biglioli - 《Bmj Case Reports》 被...

Our patient also obtained malignant cytology which confirms common statistics. As mentioned above, the tumor was less than 10 mm, but nonetheless highly suspicious lesion should be biopsied. However, preoperative correct identification of the subtype of a tumor may be beneficial to choose the ...
