Warthin tumor is a benign tumor of the salivary gland. The first symptom is usually a painless, slow-growing bump in front of the ear, on the bottom of the mouth, or under the chin. Warthin tumors may increase in size over time, but few become cancerous.
Is warthin’s tumor common?
Warthin’s tumor is the second most common benign neoplasm of the salivary glands, accounting for 2% to 6% of parotid tumors. In the parotid, it is usually found in the inferior lobe of the gland. This unusual type of tumor is a slow-growing, painless, round-to-ovoid mass.
Should a warthin tumor be removed?
Unlike pleomorphic adenomas, Warthin’s tumor presents less than 1% risk of malignant evolution . That is why surgery is not necessary when the preoperative diagnosis is certain and surgery should be avoided as often as possible because of the risk of facial nerve injury during surgery , .
How fast does a warthin tumor grow?
Warthin’s tumours appear to have an approximate average doubling time of 9 years, but can have a wide range of growth rates, with many cases showing a reduction in size.
What is warthin’s tumor?
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.
How is warthin’s tumor treated?
Treatment of Warthin tumor generally includes surgery to remove the tumor or careful observation to watch for changes in the tumor over time. Because Warthin tumor is almost always benign, additional treatment (i.e. radiation therapy and/or chemotherapy ) is rarely needed.
Can a warthin tumor become malignant?
The malignant transformation of Warthin’s tumour is extremely rare (0.3%). The malignant transformation of its lymphoid component into malignant lymphoma is relatively common, whereas, an epithelial malignancy in Warthin’s tumour is extremely rare [3,4].
Can parotid tumors go away on their own?
Salivary gland stones are the most common cause of this condition. Symptoms can include pain and swelling in the area around the back of your jaw. The condition often goes away on its own with little treatment. You may need additional treatment, such as surgery, to get rid of the stone.
Should a benign parotid tumor be removed?
Treatment Surgery is recommended for almost all parotid gland tumors, whether cancerous or benign. Although most tumors grow slowly and are non-cancerous, they will often continue to grow and occasionally can become cancerous. Treatment of a parotid tumor generally requires removing the parotid gland (parotidectomy).
What causes a benign tumor?
The exact cause of a benign tumor is often unknown. It develops when cells in the body divide and grow at an excessive rate. Typically, the body is able to balance cell growth and division. When old or damaged cells die, they are automatically replaced with new, healthy cells.
Is warthin’s tumor hereditary?
Causes of Salivary Gland Tumors
The cause of most salivary gland tumors is currently unknown, but genetic research is being conducted to uncover it. In some cases, skin cancer can spread to the parotid gland. Smoking is also known to cause one type of benign tumor, Warthin’s.
Are warthin tumors genetic?
The potential genetic predisposition of Warthins tumour, via point mutation and genetic translocation (as mentioned previously), is also supported in all of the cases described, as each case series were direct relatives.
