Definition
A benign neoplasm that arises from the ciliated respiratory mucosa that lines the nasal cavity or paranasal sinuses. It results from the invagination and proliferation of epithelial cells in the underlying stroma. Clinical manifestations include nasal obstruction, epistaxis, and anosmia. It has the tendency to recur and extend to adjacent structures. Inverted papillomas are occasionally associated with the development or presence of carcinomas, usually squamous cell carcinomas.

Key figures
Each figure carries its unit, period and source; ranks link to "Why this rank?".
No registry-level ancestor: burden figures are published for the mutually exclusive top-level site groups only, and this entity does not descend from one. Global figures (IARC / GLOBOCAN) stay under license review and SEER awaits credentials.
