A 73-year-old woman presented with a 3-month history of progressive nasal congestion and intermittent epistaxis but was otherwise systemically well. She had no significant co-morbidities and, in particular, no history of sinonasal disease or smoking. Examination revealed an expansive red polypoid mass clearly involving the right cheek and nasal cavity (Fig. 1). There was no suggestion of oral, ocular or neurological involvement. Imaging demonstrated an expansive and erosive soft-tissue mass originating in the right maxillary antrum extending posteromedially to almost completely obstruct the nasal cavity and nasopharyngeal air space (Fig. 2). Invasion into the orbit and metastatic disease were not evident. Initial biopsy suggested ameloblastoma and the patient went on to have a right total maxillec-tomy, ethmoidectomy with clearance of her right infratemporal fossa (Fig. 1).
