EPITHELIAL-MYOEPITHELIAL CARCINOMA OF THE PAROTID-GLAND

We describe an unusual salivary neoplasm, an epithelial-myoepithelial carcinoma (EMEC) of the parotid gland, that occurred in a 64-year-old man. A CT scan showed a fairly well defined heterogeneous lesion with smooth margins and slight enhancement. MR images showed a lesion with intermediate T1-weighted signal intensity and a relatively high T2-wei ghted signal intensity, Although the imaging characteristics of EMEC o n both CT and MR studies are nonspecific, clinicians and radiologists must be aware of its high local recurrence rate, which has been report ed to approach 50% in some series, and thus the need for periodic post operative imaging to detect early recurrence.
