Background: The salivary gland system of the upper aero digestive tract plays a critical role in the functions of digestion, respiration, communication, and overall homeostasis. The Salivary gland swellings can be broadly classified into inflammatory, non-inflammatory and neoplastic swellings like calculi, benign tumours such has pleomorphic adenoma, oncocytoma, Warthin's tumour, malignant tumors which include-adenocarcinoma, adenoid cystic carcinoma, undifferentiated carcinoma.

Methods: The present cross-sectional study was conducted at the Department of general surgery, Sri Siddhartha Medical College over a period of 2 years from August 2016 to July 2018.  All major salivary gland neoplastic swellings confirmed by FNAC were included in this study.

Results: In our study 23 patients had major salivary gland tumours out of that 19 patients had parotid and 4 had submandibular major salivary gland tumour. In our study out 23 cases of salivary tumours 19 cases were benign and 4 cases were malignant, out of 19 cases of parotid tumours, 15 (78.94%) cases were seen in superficial lobe and 4 (21.06%) were in deep lobe, out of 23 salivary gland tumours, 19 (82.6%) cases were pleomorphic adenoma 3(13.05%) cases were mucoepidermoid carcinoma and one case (4.35%) was acinic cell carcinoma.

Conclusions: Parotid gland was the most common site of origin of both benign and malignant tumours, Pleomorphic adenoma was the most common benign salivary gland tumour and mucoepidermoid carcinoma was the most frequent malignant neoplasm.
