salivary gland cysts

Friday 10 June 2016

Non-neoplastic cysts of the salivary glands are uncommon and represent 2-5% of all salivary gland lesions. They are mainly mucoceles or salivary duct cysts.

Cystic lesions involving the salivary glands are mostly reported to be cystic neoplasms. Few examples include pleomorphic adenoma, warthin’s tumor, mucoepidermoid carcinoma, low grade papillary cystadenocarcinoma, and metastatic squamous cell carcinoma.

Non-neoplastic cysts are a rarity and comprise 2-5% of all salivary gland lesions. Benign cysts are classified as lymphoepithelial cyst, salivary duct cyst, and dysgenetic cyst.

Salivary duct cysts are true cysts that have a congenital or acquired origin. Although literature reveals that most of the cases reported are of acquired origin, duct obstruction often seems to be the cause of the lesion.

Neoplastic differentiation of the lining of the salivary duct cyst has been reported.
