Oral Cavity Squamous Cell Carcinoma Presenting as an Isolated Nasal Mass in the Setting of a Fixed Implant-Supported Upper Denture.

Proper staging and diagnosing of mucosal head and neck cancers is necessary given important differences in tumor behaviors that lead to different standards of treatment. We report the unusual case of a 65-year-old woman who is a former smoker with an implant-supported upper denture who developed an isolated nasal mass on examination, which was confirmed after resection to be a squamous cell carcinoma originating from the hard palate. Although this is a rare scenario, an oral cavity cancer should be taken into consideration in the differential diagnosis of a nasal cavity mass in the setting of a fixed upper dental implant.
