Inverted Papilloma/Schneiderion Papilloma/Transitional Cell Papilloma/Ringertz Tumour:
- This is the MC benign tumour of the nasal cavity.
- It is a benign but locally invasive tumour.
- It is seen more commonly in men.
- It is seen mostly in the age group of 40-70 years.
- Association with HPV (human papillomavirus) has been found.
- It arises from the lateral wall of the nose and is usually unilateral.
- The patient presents with unilateral nasal obstruction and unilateral epistaxis.
- It appears like a pale polypoidal lesion with a papillary appearance that protrudes from the middle meatal area.
- On histopathologic examination, there is a proliferation of epithelium with finger-like inversions into the underlying stroma because of which it is known as inverted papilloma.
- It is premalignant with 5-15% risk of developing squamous cell carcinoma.
- Treatment consists of wide excision of the tumour by lateral rhinotomy (by giving incision in the naso-facial crease) or midfacial degloving approach (by giving sub-labial incision from one molar to the other and raising the skin flap over the cheek and nose).
- Chances of its recurrence are very high.
