Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2017, Vol 6, Issue 72
Abstract
BACKGROUND Neoplasms of the salivary gland are rare tumours with an annual incidence of 1:100000. It comprises 3% of Head and Neck Neoplasms.[1] In salivary gland tumours, the mean age is 45 years with peak incidence in 6th and 7th decade of life.[2,3] The most frequent site for salivary neoplasm is parotid gland.[4-6] Around 80% of parotid tumours are benign, the commonest being pleomorphic adenoma followed by Warthin’s tumour. Most common salivary malignancy is mucoepidermoid carcinoma involving the parotid gland.[5,7] Adenoid cystic carcinoma is the second most common malignancy. MATERIALS AND METHODS In this series, various aspects of the parotid tumours admitted in MediCiti Institute of Medical Sciences from January 2012 - January 2017 in the Department of General Surgery and ENT were analysed. A detailed study of 42 cases of parotid tumour admitted during this period is carried out. Our study comprises of benign and malignant tumours of the parotid gland and the results are compared with the data available in the literature. Study design is retrospective descriptive study. RESULTS Majority of salivary gland tumours arise from parotid gland. The mean age was 51.05 years. The present study exhibits an incidence of 64.3% benign tumours and 35.7% malignant tumours with pleomorphic adenoma accounting for 85.18% of benign tumours and about 54.76% of all parotid neoplasms. CONCLUSION Neoplasms of parotid gland are most commonly encountered salivary neoplasms. Most of them are benign. About 80% of primary salivary gland epithelial tumours are seen in parotid gland, mostly in superficial lobe. The peak age incidence was in the 50 - 60 years’ age group. Benign tumours, particularly pleomorphic adenoma is commonest presentation and the commonest malignant tumour is mucoepidermoid carcinoma.
