title: A sinonasal inverted papilloma of mixed histology: implications for management of all sinonasal papillomas.
abstract: Sinonasal papillomas are classically categorized by their histology. Inverted, cylindrical, and fungiform are the three subtypes used to describe these lesions, and their medical and surgical management is often based on the specific subtype. We describe a case of a sinonasal papilloma with all three subtypes represented within the same surgical specimen. To our knowledge, this represents the first such case in the literature and has implications for the management of all sinonasal papillomas.
