ABSTRACT
Myoepithelioma is a rare benign tumor of salivary gland myoepithelial cells, most commonly as a spindle subtype. Here, we present two cases of fine needle aspiration cytology of plasmacytoid myoepithelioma arising from a parotid gland and a hard palate. Aspirates showed plasmacytoid cells with pink-staining, homogeneous, abundant eosinophilic cytoplasm eccentrically displacing the nucleus in cohesive and dissociated forms. Rarely, nuclear grooves and intranuclear cytoplasmic inclusions were evident. These unfamiliar cytologic findings of uncommon myoepithelioma often cause diagnostic difficulties in preoperative aspiration cytology. Recognition of those rare findings provides a reliable diagnostic clue.
