Keywords: Typical findings of pleomorphic adenoma included hyperintensity on T2w images (p = 0.02), strong contrast enhancement (p < 0.001) and lobulated shape (p = 0.04). If the tumor has surrounded or invaded the facial nerve, that nerve may have to be removed along with the tumor. Eisele notes that in addition to rare instances when a pleomorphic adenoma turns malignant, a cancerous parotid tumor can arise from skin cancers such as squamous cell carcinoma or melanoma that spread (metastasize) to the gland, which has lymph nodes imbedded inside. Parotid gland tumors account for approximately 2% to 10% of head and neck tumors. 2001;46:9195. Before 2017 Oct;104(10):850-857. doi: 10.1016/j.bulcan.2017.09.001.

Prognostic nomogram for disease-specific survival of carcinoma ex pleomorphic adenoma of the salivary gland. It is important to recognize that the clinical behavior of a tumor rather than the histology can provide a better treatment guide, and it is recommended that clinical factors, in addition to histology and grade, are considered when treatment planning. The sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) for the US were established.
