The worldwide incidence is estimated at 0.5 to 3.0 per 100,000 per year, accounting for about 5% of all head and neck malignancies. The adjuvant approach in this case was decided by a multidisciplinary team given the absence of classically known risk factors. This right parotid mass demonstrates the classical imaging findings of a salivary gland pleomorphic adenoma, lobulated hypoechoic lesion on US and T1 hypointensity /STIR hyperintensity on MR. Fine needle aspiration was performed and this was confirmed as pleomorphic adenoma on cytohistopathology. 4. Chemotherapy is sometimes used to treat parotid gland cancers.

Sometimes the results say a tumor isn't cancerous when it is. You have hundreds of salivary glands in and around your mouth that create saliva, which helps to keep your mouth moist and aids in swallowing, speaking and eating. Since "parotid masses" are frequently of nonparotid origin (Table 175.1), the relationship of the mass to the gland markedly alters the management in as many as a third of patients presenting with a parotid-region mass (Figs. The use of RT in these cases is controversial and is sometimes not recommended, especially in younger patients due to the risk of radiation-induced tumors. 7. Yousem D, Kraut M, Chalian A.

Salivary gland neoplasms may be benign or malignant, and malignant tumors can be primary or metastatic. Your surgeon and team remove the parotid tumor along with some normal tissue surrounding the mass so it can be removed completely.

I parametri significativamente predittivi di malignit sono risultati i margini mal-definiti (p < 0,001), le linfoadenopatie (p < 0,001) ed il pattern di crescita infiltrativo (p < 0,001). A good rule of thumbto remember is the rule of 80s; that 80% of all salivary tumors are in the parotid, 80% of parotid tumors are benign, and 80% of the benign tumors that arise in the parotid are pleomorphic adenomas. There is thus an increasing recognition that operations less than the traditional procedures are acceptable. Anatomy for Diagnostic Imaging. 8.
