title: Primary schwannoma of maxillary sinus masquerading as malignant tumour.
abstract: Polyp and mucocele are the commonest sinonasal tumours and schwannoma is rarely found in the paranasal sinuses. We report a case of a 64-year-old man presenting with progressive nasal obstruction and numbness on left cheek for the past 2 months. 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. Tumour was excised through Caldwell-Luc's approach and histopathological examination found a mixed schwannoma.
