A case report of a parotid epithelial-myoepithelial carcinoma (EMC) of intercalated ducts is presented. There were no changes in clinical characteristics or growth over a four-year period as documented by repeated clinical examination and serial ultrasounds. This neoplasm may be mistaken for an adenoid cystic carcinoma on fine needle aspiration and is believed to represent an adenocarcinoma of low malignant potential. The imperceptible growth of this epithelial-myoepithelial carcinoma is in accord with a low malignant potential.
