Epithelial-myoepithelial carcinoma (EMC), a low-grade malignant neoplasm of glandular origin, most commonly involves major and occasionally minor salivary glands. It is rare in minor salivary glands such as hard and soft palate, buccal mucosa, tongue, and so on, frequently affecting geriatric females. EMC comprises diverse histo-pathologic features of an epithelial, myoepithelial de-lineating biphasic pattern along with clear cells, sometimes oncocytic differentiation. Aberrant histo-pathologic features in EMC need judicious discrimination from alike entities, which facilitates appropriate surgical management. Here, we present an unusual case report of EMC in the left retro-molar trigone region in a 60-year-old male patient, the complete diagnosis of which was based on clinical, radiological, histo-pathological, and immuno-histo-chemical features.
