The salivary glands are classified as major or minor. The major salivary glands consist of the parotid, submandibular, and sublingual glands. The minor salivary glands consist of 800 to 1000 small mucus-secreting glands located throughout the lining of the oral cavity. [2] Patients with these types of tumours may be asymptomatic. [1]
Adenoid cystic carcinoma is a rare type of cancer that can exist in many different body sites. This tumor most often occurs in the salivary glands, but it can also be found in many anatomic sites, including the breast, [1] [2] lacrimal gland, lung, brain, Bartholin gland, trachea, and the paranasal sinuses.
Lung cancer is a large and exceptionally heterogeneous family of malignancies. [3] Over 50 different histological variants are explicitly recognized within the 2004 revision of the World Health Organization (WHO) typing system ("WHO-2004"), currently the most widely used lung cancer classification scheme.

Salivary duct carcinoma (SDC) is a rare type of aggressive cancer that arises from the salivary glands. [1] It is predominantly seen in men and, generally, has a poor prognosis. [2] Other high grade carcinomas can mimic SDC. About 40-60% of SDC arise in pleomorphic adenomas. [3] Most, if not all, SDCs express androgen receptor by ...
The signs and symptoms are similar to other malignant salivary gland tumours; however, it may have been preceded by an appreciable mass that was long-standing and did not appear to be growing. Findings that suggest a malignant salivary gland tumour include rapid growth, facial weakness (due to facial nerve compression), pain , skin ulceration ...
Survival rates due to malignancy depends on the patient and extent of disease. [4] A 10-year survival ranges from 32-83%. [4] Of all cancers, salivary gland tumors account for only 1%. [4] Parotid tumors account for 7% of all head and neck cancers. [4]
Acinic cell carcinoma is a malignant tumor representing 2% of all salivary tumors. 90% of the time found in the parotid gland, 10% intraorally on buccal mucosa or palate. The disease presents as a slow growing mass, associated with pain or tenderness in 50% of the cases. Often appears pseudoencapsulated.
Head and neck cancer is a general term encompassing multiple cancers that can develop in the head and neck region. These include cancers of the mouth, tongue, gums and lips (oral cancer), voice box , throat (nasopharyngeal, oropharyngeal, [1] hypopharyngeal), salivary glands, nose and sinuses. [5]
