title: [Oncocytic papilloma in nasal cavity and paranasal sinuses: 3 of cases].
abstract: Oncocytic papilloma (OP) of nasal cavity and paranasal sinuses are uncommon. We report 3 cases of oncocytic papilloma arising in the nasal cavity and paranasal sinuses, and review the relevant literatures. Unilateral sinonasal lesions are the main clinical manifestation. Pathological feature is multiple layers of epithelial cells. The cytoplasm contains abundant eosinophilic granular and microcapsules filling with mucus. The neutrophils aggregate in the microcapsules which form microabscess. The tendence of recurrence and malignant transformation are the biological character. The best treatment choice is surgical excision completely, and long-term postoperative follow-up is necessary to prevent relapse.
