Abstract:
Fibroepithelial polyps are benign tumors of mesodermal origin. They rarely occur in the nasal cavity, with only four such cases reported in the relevant English literature. The location was the inferior turbinate in three cases and anterior nasal septum in one case. The etiology has been suggested in other organs; however, it is entirely unknown in the nasal cavity. Pathological findings play an essential role in the diagnosis of fibroepithelial polyps. We report the case of a 76-year-old woman with fibroepithelial polyps originating from the posterior part of the nasal septum. The fibroepithelial polyps were white-yellow lobular masses that differed from a common inflammatory polyp. We made the diagnosis by excluding the other possible tumors based on a pathological examination. This is the first report about fibroepithelial polyps arising from the posterior nasal septum. She had no potential risk factors that might trigger fibroepithelial polyps in the nasal cavity. This case is a valuable example when considering the potential causes (e.g., female hormones and mechanical pressure) of nasal fibroepithelial polyps.
Insights
This case study details a rare nasal fibroepithelial polyp in a 76-year-old woman. The findings highlight the importance of pathological examination for diagnosing these benign tumors.
Area of Science:
- Otorhinolaryngology
- Pathology
- Oncology
Background:
- Fibroepithelial polyps are rare benign tumors of mesodermal origin.
- Their occurrence in the nasal cavity is exceptionally uncommon, with limited documented cases.
Observation:
- A 76-year-old woman presented with white-yellow lobular masses from the posterior nasal septum.
- These masses were pathologically identified as fibroepithelial polyps, distinct from inflammatory polyps.
Findings:
- This case represents the first reported instance of fibroepithelial polyps originating from the posterior nasal septum.
- The etiology of nasal fibroepithelial polyps remains unknown, with no identified risk factors in this patient.
Implications:
- Accurate pathological examination is crucial for diagnosing nasal fibroepithelial polyps.
- This case provides valuable insights into potential etiological factors, such as hormonal influences and mechanical pressure.
