Diagnosis of Salivary Gland Lesions By Fine Needle Aspiration Cytology and Its Histopathological Correlation in A Tertiary Care Center of Southern India.
BACKGROUND
Salivary glands may enlarge either due to inflammation or neoplastic conditions and the diagnosis is possible by fine needle aspiration cytology (FNAC).


OBJECTIVE
The present study was undertaken to determine utility of FNAC in the diagnosis of salivary gland lesions.


METHODS
In this retrospective study, a total of 186 FNACs of salivary gland lesions were retrieved and evaluated. Of these, 146 cases had follow-up histopathological diagnosis. FNAC diagnoses were compared to histopathological diagnoses.


RESULTS
The parotid glands were more commonly involved than others. Among the various diagnostic categories used in FNAC reports, Non neoplastic category was seen in 24 (16.4%), benign category in 86 (58.9%) and malignant category in 30 (20.6%) and unsatisfactory category in 6 (4.1%) of 146 cases. The overall sensitivity, specificity, accuracy, positive predictive value and negative predictive value of FNAC in the diagnosis of salivary gland lesions were 86.6%, 94.6%, 93.6%, 88.3%, and 94.6% respectively.


CONCLUSIONS
The present study concluded that FNAC in the diagnosis of salivary gland lesions is highly sensitive, specific and accurate method. Hence, FNAC is a useful, quick and reliable diagnostic tool. It also appears to be a safe, cost effective and minimally invasive procedure, which provides information for management of salivary gland lesions.
