A second technique for locating the facial nerve is to identify a distal branch of the nerve and to dissect retrograde toward the main trunk. Nonneoplastic causes of parotid enlargement include cysts, parotitis, lymphoepithelial lesions associated with AIDS, collagen vascular diseases, and benign hypertrophy. Examples of criteria for the description of the echogenicity (slightly hypoechoic, highly hypoechoic) and the homogeneity (slightly heterogenous, highly heterogenous) of the parotid gland tumors: US of malignant parotid glands tumors: SCCpoor defined margins, highly hypoechogenic, slightly heterogenic, and poor vascularity pattern (, US of: PA with irregular shape, well-defined margins, slightly hypoechogenic, slightly heterogenic, and no vascularity (. Warthin tumour of the left parotid gland (69-year-old male). Imaging of parotid gland tumors is challenging due to the wide variety of differential diagnoses. https://www.nccn.org/guidelines/guidelines-detail?category=1&id=1437. Clipboard, Search History, and several other advanced features are temporarily unavailable. A recent study demonstrated that epidermal growth factor receptor (EGFR) is expressed strongly in the cell membranes of parotid mucoepidermoid carcinomas and of the lymph node metastases. Multivariate analysis also indicated that reduced cause-specific survival is associated with age over 50 years at diagnosis, greater tumor size, regionalor distant tumor involvement, tumor grade of III/IV at diagnosis, lack of surgery, and male sex. Federal government websites often end in .gov or .mil. Objectives: WebHome CCC Differential diagnosis Overview Parotid swelling or enlargement can be unilateral or bilateral, suggesting different underlying causes. Salivary gland disorders. National Comprehensive Cancer Network. -. The major salivary glands include the paired parotid, submandibular, and sublingual glands which are collectively responsible for the production of over 95 percent of saliva. Receiver operating characteristic curves were constructed to determine the predictive values of echogenicity, heterogeneity, and vascularity on color Doppler. In the absence of an easily recognizable mucous cell population, the diagnosis is challenging, often requiring ancillary studies such as special (mucin) stains, immunohistochemistry, and detection of classical MEC Often, regional nodes also are enlarged.
