Which of the following is the most common benign salivary gland type tumour of the sinonasal tract?

• A Pleomorphic adenoma, most often arising from the nasal septum ✓
• B Adenoid cystic carcinoma, most often arising from the lateral wall
• C Mucoepidermoid carcinoma, most often arising from the septum
• D Oncocytoma, most often arising from the maxillary sinus

Explanation

Pleomorphic adenoma is the commonest benign tumour of minor salivary gland origin in the sinonasal tract, and within this region the nasal septum is the most frequently involved subsite. Adenoid cystic carcinoma and mucoepidermoid carcinoma are malignant, so they cannot be answers to a question about benign salivary type tumours. Oncocytoma is distinctly uncommon at this site.
