title: Squamous papilloma of the oral cavity and oropharynx on 18F-FDG PET/CT imaging.
abstract: Squamous papilloma is one of the most common benign neoplasms of the oral cavity and oropharynx. The (18)F-FDG PET/CT metabolic phenotype of this entity has not been described. We document the incidental finding of a hypermetabolic lesion at the right base of the tongue on an FDG PET/CT that proved to be squamous papilloma. The maximum standard uptake value was high at 7.0 g/ml. We conclude that oral cavity squamous papilloma can present with an intensely hypermetabolic phenotype on (18)F- FDG PET/CT. This benign entity should be included in the differential diagnosis of FDG-positive oral and oropharyngeal lesions.
