Synopsis

An uncommon collection of tumors originating from within the salivary glands that can include tumors within the parotid gland, the submandibular gland, and the sublingual gland. There are various subtypes of salivary adenocarcinomas ranging from low grade to high grade. Characterized by generalized weakness, dysphagia, mouth and neck pain, neck mass, facial palsy, oral tumor or sublingual cyst, trismus, and parotid enlargement.

Management depends on the extent and location of the malignancy and may include surgical salvage, complete resection of tumor, radiation therapy, and, in the case of metastatic disease, chemotherapy for palliation.
