Abstract

Background: Fine needle aspiration cytology (FNAC) is a cytodiagnostic method based on morphologic findings of individual and small group of cells aspirated using a fine needle. The aim of the present study is to evaluate the spectrum of salivary gland lesions in our setting and to assess the diagnostic accuracy of FNAC for salivary gland lesions.
Methods: The study involved 100 cases of parotid and submandibular swellings of patients who underwent FNAC at our institution. 20 patients with a FNAC diagnosis of neoplastic lesion subsequently underwent excision biopsies. The results of FNAC and final histology were compared and accuracy of FNAC was determined.
Results: Out of 30 cases of salivary swellings 20 cases were of pleomorphic adenoma. 3 case of chronic sialadinitis, 2 cases of sialadinosis, and remaining 5 cases were neoplastic salivary gland lesions comprising of 3 case of meucoepidermoid carcinoma, and 2 case of acinic cell carcinoma. So these 5 cases which was given as neoplastic were operated and specimen were obtained and it was confirmed in histopathology. Also the 20 cases of pleomorphic adenoma were operated and correlated positively with histopathology.
Conclusion: FNAC is a good preliminary investigation in salivary gland lesions with 100% sensitivity and specificity. We found a good concordance between FNAC and final histology, which reduces unnecessary surgical intervention.
