A 53 year-old-male complained of right nasal obstruction and mucopurulent nasal discharge. He had no past history of sinusitis. A polypous granular tumor was observed in his right nasal cavity. Roentgenograms showed abnormal shadows in the right maxillary sinus and right nasal cavity. Tomography showed the destruction of the medial wall of the right maxillary sinus. First biopsy of the tumor showed chronic inflammation. But we suspected maxillary cancer from its destructiveness, and performed extirpation of the tumor via the right maxillary sinus after 400 rad irradiation.
Histologic examination of the tumor showed typical inverted papilloma with no malignancy.
3200 rad irradiation was performed post-operatively to prevent recurrence, and no recurrence was observed until now.
