Fine needle aspiration (FNA) cytology of suspected salivary gland lesions has an established role in preoperative diagnosis and management of patients. However diverse morphological patterns and overlapping features make it a challenging job, to give a precise diagnosis, at times. The aim of the present study is to investigate the accuracy of FNA cytology of salivary gland lesions by correlation between histology and cytology.
One hundred salivary gland FNA specimens collected during 2002 – 2008 from 100 patients were reviewed and correlated with histopathology findings. Considering the results of histopathology as the diagnostic standard, the sensitivity, specificity, and accuracy of FNA cytology in diagnosis were 67, 100, and 96%, respectively. This
study demonstrated that FNA cytology of the salivary gland is an effective and useful technique for diagnosis of salivary gland lesions. Accuracy depends on experience of both pathologists who interpret the specimens and surgeons and clinicians who perform the FNA.
