Abstract
BACKGROUND: Salivary glands may enlarge either due to inflammation or neoplastic conditions and the diagnosis is possible by fine needle aspiration cytology (FNAC). AIM: The present study was undertaken to determine utility of FNAC in the diagnosis of salivary gland lesions. MATERIALS AND 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. CONCLUSION: 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.
