Abstract
Inverted papilloma arising from the nasal cavity and paranasal sinuses is a relatively uncommon benign tumor. We report a case of inverted papilloma in the maxillary sinus that developed after extraction of the right upper first and second molars.
A 42-year-old man was referred to our clinic because of a developing mass, which had been found by a dentist after extraction of the first and second molars on December 21, 1984. Intraoral examination demonstrated an elastic hard mass about the size of the thumb in first and second molar region.
Radiographic examination revealed a cloudy area in the right maxillary sinus.
The mass was extirpated with the patient under intravenous sedation. The histopathological diagnosis was inverted papilloma. Examination 10 years after the operation showed on sign of recurrence of the lesion.
