Cytologic features of solitary fibrous tumor of the parotid gland. A case report.
BACKGROUND
Solitary fibrous tumor (SFT) is a rare neoplasm that most commonly involves the pleura but is increasingly recognized at other locations, including lung, liver, thyroid and parotid glands, with only a few reports describing its cytologic features.


METHODS
The fine needle aspiration biopsy (FNAB) features of an SFT located in the left parotid gland of a 34-year-old woman were compared to the histologic and immunohistochemical aspects of the lesion.


CONCLUSIONS
This case confirms that SFT has distinct cytomorphologic features and that FNAB can be helpful in its diagnosis.
