We report a case of a 64-year-old man presenting with progressive nasal obstruction and numbness on left cheek for the past 2\u2005months. High-resolution CT found a soft tissue mass in the maxillary antrum with bony destruction. Clinical features, radiological scan and nasal endoscopic examination were suggestive of a malignant tumour.
