Which of the following is the most common malignant tumour of the paranasal sinuses?

• A Adenocarcinoma
• B Olfactory neuroblastoma
• C Adenoid cystic carcinoma
• D Squamous cell carcinoma ✓

Explanation

Squamous cell carcinoma accounts for roughly 80 percent of all malignant neoplasms of the nose and paranasal sinuses, and the maxillary antrum is the most frequently involved sinus. Adenocarcinoma is the next common type and has a specific link with hardwood dust exposure in furniture and wood workers. The other listed malignancies are far less frequent. This distribution holds in both Western series and Indian textbook data such as Dhingra.
