Abstract:
Objective : To explore the cytological features of various salivary gland epithelial neoplasms.
Methods : Two hundred and fifty-three patients with salivary gland epithelial neoplasms were diagnosed by fine needle aspiration cytology (FNAC). All of the cases were compared with histopathologic findings.
Results : The total correspondence rate of salivary gland epithelial neoplasms between cytological and pathologic results was 95.7%. The coincidence for the benignity and the malignancy was 98.1%(203/207) and 84.8%(39/46), respectively. Different characteristic morphological manifestations of cellular and interstitial components were found in same type of tumors. Some well differentiated salivary gland carcinomas could show differentiated oncocytes similar to benign cells.
Conclusion : Cytodiagnosis is an ideal method for clinical diagnosis of salivary gland epithelial neoplasms as its higher sensitivity and specificity. The misdiagnostic reasons attribute mainly to inadequate sample, lacking histologic architecture.
