A REVIEW OF SINONASAL SALIVARY GLAND TYPE TUMOURS FROM CASE FILES OF A TERTIARY CARE HOSPITAL

Background and Objective - Malignancies of nasal cavity and paranasal sinuses account for 0.2-0.8 percentage of all malignant neoplasms and 3 percentage of those occurring in head and neck. In sinonasal tumours 60 percentage occur in maxillary sinus, 20-30 percentage in nasal cavity, 1 percentage in sphenoid and 15 percentage in ethmoid sinus. This study analyses the clinical and pathological findings of sinonasal salivary gland type tumours reported in our institution in the past 6 years. Materials and methods - The clinical and pathological materials of 20 patients diagnosed with salivary gland type tumours from Jan 2007 to Dec 2012 were considered for the study. The clinical and pathological findings were evaluated. Results - Of the 20 cases reported, the most common histological subtype was adenoid cystic carcinoma followed by mucoepidermoid carcinoma. About 73 percentage occurred in females and 27 percentage in males. Average age of presentation was 51 years. Out of the 20 cases 3 were recurrent lesions. Conclusion - A knowledge about the heterogeneous types of salivary gland tumors in nose and paranasal sinuses help in their correct diagnosis, proper treatment and prediction of their clinical behavior.
