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. The facial nerve and its branches pass through the parotid gland, as does the external carotid arteryand retromandibular vein. The energy can come from sources such as X-rays and protons. 12. 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). 23 (5): 353-4. The radiation can kill any cancer cells that remain. 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. How much of the parotid gland do you plan to remove? The surgeon makes an incision (cut) in the skin to reach the parotid gland.
