To investigate the features and correlation of nasal inverted papilloma complicated with polyps.
Twelve patients diagnosed as nasal inverted papilloma complicated with polyps were studied. The pathological specimens were taken from the surface, core and base of papilloma and sinus in every patient. Through comparing pathological findings, the features and correlation of nasal inverted papilloma complicated with polyps were evaluated.
In most cases, nasal inverted papilloma was located in the core and base of the mass, while the polyps were located in the surface of the mass.
Nasal inverted papilloma complicated with polyps may result from long-term inflammation that occurred in the surface of the epithelia of superficial papilloma. Therefore, the occurrence of neoplastic disease in core should be alerted in unilateral nasal polyp case.
