Warthin tumor (WT) is the second most common benign salivary gland tumor, accounting for 12-37% of parotid gland neoplasms [1, 2].WT is believed to arise from salivary gland remnants that reside within the intra-parotid lymph nodes [].Typically, it presents in the fifth to seventh decades of life, with historically strong male predilection; currently, there is an increase in the incidence of .

If the nerve is sacrificed because of involvement, then primary nerve grafting should be performed. Salivary glands are a common source of benign pathology; malignant tumors are rare. eCollection 2022 Feb. Vernuccio F, Arnone F, Cannella R, Verro B, Comelli A, Agnello F, Stefano A, Gargano R, Rodolico V, Salvaggio G, Lagalla R, Midiri M, Lo Casto A. Br J Radiol. The differential diagnosis of a parotid lesion is broad, and the otolaryngologist must consider inflammatory, neoplastic, autoimmune, traumatic, infectious, or congenital causes. Although high-grade malignancies of the parotid gland usually have poorly defined margins, low signal intensity on T2-weighted images and invasion of surrounding structures, tumour margins, homogeneity, and signal intensity are not discriminative factors for correctly predicting benign or malignant tumours [12]. Facial nerve involvement generally suggests a malignant tumor, which may present with pain or paralysis. Operations used to remove parotid tumors include: To get to the parotid gland, surgeons make a cut in the skin near the ear. It has superficial and deep lobes, separated by the facial nerve. Stage I and II cancers have good cure rates, although the prognostic survival curve never flattens even after 20 years. Following surgery, the patient developed temporary facial paralysis. 2020 Dec;9(6):2295-2311. doi: 10.21037/gs-20-530.

Authors It is a relatively painless procedure, has few complications (seeding of the tumor does not seemto occur), and may prevent an ill-advised and often ill-fated incisional or excisional biopsy of a parotid mass. There is one parotid gland on each side of the face. Bilateral parotid tumors are most common in Warthin tumors and HIV related lymphoepithelial cysts. 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. Aktan ZA, Bilge O, Pinar YA, Ikiz AO. Because of the possibilityof recurrence and distant metastasis,patients with a history of salivary gland, cancermustbe monitored throughout their lifetime.

A doctor who uses blood and body tissue to diagnose diseases, who is called a pathologist, looks at the sample right away. On the other hand, lesions occurring in the submandibular gland and the minor salivary glands are more likely to be malignant. Parotid swelling or enlargement can be unilateral or bilateral, suggesting different underlying causes. About 20% of parotid tumors are malignant, with higher percentages for children, for the submandibular gland, and for intraoral minor salivary glands. Taking a detailed history is important in treating patients with parotid lumps, as infectious, autoimmune, and inflammatory processes may masquerade as neoplasms.
