Diagnosis of Salivary Gland Lesions By Fine Needle Aspiration Cytology and Its Histopathological Correlation in A Tertiary Care Center of Southern India

摘要

Background: Salivary glands may enlarge either due toinflammation or neoplastic conditions and the diagnosis ispossible by fine needle aspiration cytology (FNAC).Aim: The present study was undertaken to determine utility ofFNAC in the diagnosis of salivary gland lesions.Materials and Methods: In this retrospective study, a totalof 186 FNACs of salivary gland lesions were retrieved andevaluated. Of these, 146 cases had follow-up histopathologicaldiagnosis. FNAC diagnoses were compared to histopathologicaldiagnoses.Results: The parotid glands were more commonly involvedthan others. Among the various diagnostic categories used inFNAC 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 predictivevalue and negative predictive value of FNAC in the diagnosis ofsalivary gland lesions were 86.6%, 94.6%, 93.6%, 88.3%, and94.6% respectively.Conclusion: The present study concluded that FNAC in thediagnosis of salivary gland lesions is highly sensitive, specificand accurate method. Hence, FNAC is a useful, quick andreliable diagnostic tool. It also appears to be a safe, costeffective and minimally invasive procedure, which providesinformation for management of salivary gland lesions.
