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