Myoepitheliomas of intraoral minor salivary glands are rare and are usually of plasmacytoid type. Myoepitheliomas are considered difficult to diagnose without the aid of ultrastructural and histochemical studies. Here we present a case report of plasmacytoid type of myoepithelioma of palate that was diagnosed by light microscopic examination alone. Considering the non-specificity of ultrastructural and histochemical findings, it is important to pay attention to typical features of plasmacytoid myoepitheliomas to arrive at a diagnosis.

Myoepitheliomas are very rare salivary gland neoplasms seen mainly in the major salivary glands (~40%) followed by minor salivary glands (~21%). Palatal myoepitheliomas are rare, with clear cell types being even rarer. Due to the rarity of this tumor, it lacks specific features that are diagnostic in cytology.

Although myoepithelioma is defined as a benign tumour made up primarily of neoplastic myoepithelial cells, its actual histopathological characteristics are highly diverse. It can be considered a rare disease. The most common site of occurrence is the parotid gland, followed by the minor salivary glands of the palate.

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.
