salivary myoepithelial tumors

Thursday 31 January 2008

Myoepithelial neoplasms have been first described in the salivary glands. Then, they have also been recognized in the breast, upper aerodigestive tract and skin, and can arise primarily in soft tissue, albeit infrequently.

Myoepithelial carcinomas comprise less than 2% of all salivary gland carcinomas and occur at a mean age of 55.

Although approximately half of salivary gland myoepithelial carcinomas arise in association with a benign mixed tumor or myoepithelioma.

Myoepithelial tumors

Myoepithelial tumors are well recognized in the salivary gland, where they include salivary benign mixed tumors and salivary myoepitheliomas, which are distinguished by the degree or presence of ductal differentiation, and myoepithelial carcinomas.
