  • Title: Fine-needle aspiration cytological findings in five cases of epithelial-myoepithelial carcinoma of salivary glands.
    Author: Miliauskas JR, Orell SR.
    Journal: Diagn Cytopathol; 2003 Mar; 28(3):163-7. PubMed ID: 12619100.
    Abstract:
    The cytologic features of five cases of epithelial-myoepithelial carcinoma arising in major salivary glands (four parotid and one submandibular gland) are presented. All cases were initially diagnosed as low-grade malignancies. The smears were generally cellular, with no specific architectural pattern. Single cells and naked nuclei were prominent in all cases. A biphasic epithelial (small-cell) and myoepithelial (large/clear-cell) pattern was identified readily in two cases and with difficulty in one case. The biphasic pattern may be subtle or absent since the clear cells have a fragile cytoplasm and often appear as naked nuclei. The differential diagnosis includes adenoid cystic carcinoma, polymorphous low-grade adenocarcinoma, and cellular pleomorphic adenoma.
