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.
Mucoepidermoid carcinoma (MEC) [ 1] is the most common type of minor salivary gland malignancy in adults. Mucoepidermoid carcinoma can also be found in other organs, such as bronchi, lacrimal sac, [ 2] and thyroid gland . Mucicarmine staining is one stain used by pathologist for detection. [ 3]
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]
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]
Salivary gland tumours, also known as mucous gland adenomas [ 1] or neoplasms, are tumours that form in the tissues of salivary glands. 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 ...
Polymorphous low-grade adenocarcinoma. Low magnification micrograph of a polymorphous low-grade adenocarcinoma, showing the typical variation of architectural arrangement. H&E stain. Polymorphous low-grade adenocarcinoma ( PLGA) is a rare, asymptomatic, slow-growing malignant salivary gland tumor. [1] It is most commonly found in the palate.
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 ( laryngeal ), throat ( nasopharyngeal, oropharyngeal, hypopharyngeal ), salivary glands, nose and sinuses. [ 5]
