Schwannomalike mixed tumor of the parotid gland: a case report.
BACKGROUND
Schwannomalike mixed tumor is a rare benign tumor of the parotid glands.


METHODS
A 75-year-old woman presented with a tumor 3 cm in diameter localized in her left parotid gland. Fine needle aspiration (FNA) of the lesion revealed 2 types of cells: 1 with elongated, wavy, hyperchromatic nuclei and a scant cytoplasmic border and 1 with larger, weakly staining nuclei and more abundant cytoplasm. Morphologic examinations were performed.


CONCLUSIONS
FNA cytology was very useful in the diagnosis of this rare tumor of the parotid gland.
