Epithelial-myoepithelial carcinoma ex pleomorphic adenoma of the parotid gland with unique histologic differentiation: A rare case report

Epithelial myoepithelial carcinoma (EMC) is an uncommon low-to-intermediate grade salivary gland malignancy that accounts for 1% of all tumors arising in salivary glands. About 80% of these tumors affect the parotid gland. These lesions either arise de novo or from existing pleomorphic adenoma (PA)....

description Epithelial myoepithelial carcinoma (EMC) is an uncommon low-to-intermediate grade salivary gland malignancy that accounts for 1% of all tumors arising in salivary glands. About 80% of these tumors affect the parotid gland. These lesions either arise de novo or from existing pleomorphic adenoma (PA). Histologically, these tumors reveal a biphasic cell population with inner ductal epithelial cells and peripheral myoepithelial cells. There are many histologic variants of EMC, but sebaceous, verocay-like differentiation and high-grade transformation is very rarely reported. This article describes a 48-year-old female patient diagnosed with EMC ex PA with unique histologic differentiation.
