摘要
BACKGROUND: Intraparotid schwannoma of the salivary gland is a rare entity. Review of the literature revealed one previous report describing its cytologic feat tires. CASE: A 22-year-old man had a slowly growing, painless mass in the left parotid gland. Fine needle aspiration biopsy, performed prior to surgical excision, showed several tissue fragments consisting of uniform, spindle-shaped neoplastic cells with cigar-shaped nuclei and scant, ill-defined cytoplasm. Some of the neoplastic cells were clustered in typical arrangements of Verocay bodies. In addition, lymphocytes and foamy histiocytes were found. A diagnosis of schwannoma was made. Pathologic evaluation of the resected parotid mass supported the diagnosis. CONCLUSION: The diagnosis of intraparotid schwannoma can be made by examining cytologic material containing the characteristic Verocay bodies. The correct cytologic diagnosis of this entity helps to rule out morphologically similar primary salivary gland neoplasms and thereby permits the appropriate surgical procedure to ensue.
