(2003) AJNR. About 20% of parotid tumors are malignant, with higher percentages for children, for the submandibular gland, and for intraoral minor salivary glands. In: StatPearls [Internet]. Warthin tumor is the 2nd most common benign lesion. Accessed Dec. 2, 2022. The submandibular duct (Wharton duct) orifice is found on the floor of the mouth, and the parotid (Stenson duct) is situated opposite the uppersecond molar. A prophylactic selective neck dissection (levels I to III) should be performed for patients with high-stage (T3/T4) disease-free clinically high-grade tumors (i.e., high-grade mucoepidermoid carcinoma, carcinoma ex-pleomorphic adenoma, adenocarcinoma, squamous and undifferentiated carcinomas). Ishibashi M, Fujii S, Kawamoto K, Nishihara K, Matsusue E, Kodani K, Kaminou T, Ogawa T. Acta Radiol.

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]. 8600 Rockville Pike 2010 Dec;51(10):1103-10. doi: 10.3109/02841851.2010.519716. When this happens, you might experience weakness of your face, or a part of it, on one side. Salivary gland tumors represent 5%to 10%of tumors within the head and neck.1 Of these, 80% arise from the parotid gland.1 The ability of otolaryngologists to appropriately eval-uate and treat parotid masses is vitally important. 1998-2023 Mayo Foundation for Medical Education and Research (MFMER). Radiation exposure has been linked to parotid gland carcinomas 15 years afterthe event. 9. In experienced hands, this can distinguish malignant from benign disease in 80% to 90% of cases. Loss of appetite. (2009) Acta Radiologica. Review the treatment and management options available for salivary gland tumors. Tumors arising in minor salivary glands are not included in this classification. The age of the patient helps narrow the differential diagnosis, with vascular and congenital lesions being more frequent in the 1st year of life, while solid tumors are more frequent in older children. 2017 Oct;104(10):850-857. doi: 10.1016/j.bulcan.2017.09.001. There are two main theories of how salivary gland tumors arise, but theconsensusis with the multicellular theory, that each tumor type forms from a specificdifferentiated cell of origin within the salivary gland unit. Robert Hermans. Careers. Squamous carcinoma of the left parotid gland. Bethesda, MD 20894, Web Policies The facial nerve may be encased in scar tissue, so the traditional method of finding it may have to be augmented by exposing it in the mastoid bone, or more hazardously a peripheral branch traced back.

A diagnosis of cystic teratoma of the parotid gland was established preoperatively and confirmed by postoperative pathology. Local recurrences are common, and distant metastases occur in 30% to 40% patients, usually in the lungs, many years later. It might be needed if there's a risk that the cancer might spread or if surgery isn't an option. [5][6]The overall 5-year survival of malignant salivary disease depends on the stage of the disease but has been reported around 70%. differential diagnosis of Warthin tumor from mucoepidermoid car- .

Cheung RL, Russell AC, Freeman J. eCollection 2021. The commonest benign tumor (pleomorphic adenoma) has a malignant transformation potential, and, although considered benign, there is a propensity for recurrence after treatment. Your surgeon and team remove the parotid tumor along with some normal tissue surrounding the mass so it can be removed completely. It is also important to remember that the parotid gland is a common site for metastases from squamous cell carcinomas arising in the skin of the head and neck. Cigarette smoking and alcohol is associated with head and neck squamous cell carcinoma, skin malignancies in the head and neck have been known to metastases to the parotid glands. Cystic lesions observed in parotid glands are relatively rare and comprise 2-5% of all parotid primaries. 6. Signs and symptoms of malignant parotid tumours: an objective assessment.

Unable to load your collection due to an error, Unable to load your delegates due to an error, Squamous carcinoma of the left parotid gland. Overall ~80% of all parotid masses are benign and the majority of these are pleomorphic adenomas. Polymorphous adenocarcinoma is increasingly recognized, particularly as a tumor of the minor salivary glands on the soft palate. Associated neck nodes are common so that these cases should also have an elective selective neck dissection, even in an N0 neck. Ultrasoundis often the first diagnostic procedure to evaluate morphological and structural changes of the parotid gland; for small (<3 cm) and superficial lesions, ultrasound and cytology are often sufficient for a definitive diagnosis 2. appears homogeneous with increased echogenicity compared to nearby muscle 1, intraparotid lymph nodes are normally seen (unlike the submandibular gland), retromandibular veinand external carotid artery are also easily seen and by inference the facial nerve, which lies lateral to these vessels 1, difficulty visualizing deep lesions: the deep lobe is not able to be assessed as it is protected by the mandibular ramus, CT and MRI provide useful additional diagnostic imaging if malignancy is suspected 4, with the sensitivity approaching 100% for detecting parotid neoplasms 5, the parotid duct and retromandibular vein are usually seen and approximate the plane separating the superficial and deep lobes 12, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys.

Fine-needle aspiration biopsy (FNA) is the primary diagnostic tool for salivary gland lesions, but the role of FNA in the diagnosis of benign and malignant salivary gland disease still carries some controversy. The differential diagnosis includes mucous retention cyst, unilateral blockage of the parotid duct, benign mesenchymal tumors like lipoma, fibroma, hemangioma or neurofibroma, branchial cleft cyst, benign salivary gland tumors like pleomorphic adenoma, Warthin's tumor and malignant salivary gland tumor like muco-epidermoid tumor [3, 6]. Superficial parotidectomy for a benign salivary gland tumor. For distinguishing malignant from benign tumors, the highest AUC values noted were for heterogeneity and vascularization (0.8 and 0.743, respectively). Salivary fistula: saliva leaking through the incision (this is usually temporary), Sialocele: a cavity or cyst containing saliva, Freys syndrome: a rare complication of parotid gland surgery that causes sweating or flushing in an area of the face when eating, especially spicy, salty or sour foods, Seroma: a pocket of serum that forms near the surgical incision. .

Recurrence will occur if there has been incomplete excision and may occur if there has been tumor spillage. There is a high rate of transient facial nerve paresis in this group of patients. Excretory stem cells give rise to mucoepidermoid and squamous cell carcinomas, while intercalated stem cells can lead to pleomorphic adenomas, adenoid cystic carcinomas, oncocytomas, adenocarcinomas, and acinic cell carcinomas. Management of salivary glandcancer needs an interprofessional approach involving a team that consists of an otolaryngologist, a maxillofacial surgeon, a pathologist, and a radiologist. The role of imaging in the evaluation of parotid disease. Treatment usually involves surgery to remove the tumor completely. Other symptoms include problems swallowing or a loss of facial movement. You might consider asking: Radiation therapy uses powerful energy beams to kill cancer cells. The pathologist also might test nearby lymph nodes and other tissue for signs of cancer. Preoperative tumor localization, differential diagnosis, and subsequent selection of appropriate treatment for parotid gland tumors is critical.
