Myoepitheliomas and malignant myoepitheliomas were considered a variant of pleomorphic adenomas until 1991. However, these are also found in the breast and bronchus and have gained recognition as separate entities 1.
They account for <1% of salivary gland tumors, and only rarely undergo malignant transformation (0.2-0.45% of all malignant salivary gland tumors). The age of presentation ranges from 20-60 years of age 1.
Imaging appearance is essentially the same as pleomorphic adenomas 1.
