Monireh Halimi et al. J Oral Maxillofac Pathol. 2012 May.

Abstract

The inverted papilloma is a unilateral sinonasal benign tumor which is characterized by aggressive local invasion, high recurrence rate, and transformation into malignancy. The etiology of inverted papilloma is still unknown. Possible causes include allergy, chronic sinusitis, occupational exposure to dusts and aerosols, tobacco, and viral infections. Treatment is complete surgical excision and close postoperative follow-up is necessary. Here we report a case of inverted papilloma arising from the hard palate with malignant transformation in a 41-year-old female. Clinical and histological features and treatment are discussed with the review of literature.

Keywords: Inverted papilloma; malignant transformation; palate.
