Ref. Dhingra 5th/ed p 216;

Inverted papilloma is a transitional cell papilloma also called Schneiderian papilloma/Ringertz Tumor.

It is the most common benign neoplasm of the nose and paransal sinuses.

It presents in the middle age (40-70 years) as soft friable mass resembling polyp.

More common in males (male:female = 5:1).

Arises almost exclusively from the lateral wall of the nose and only occasionally from the septum. Can extend into the ethmoid and maxillary sinuses.

It is always untlateral."

Patients mainly complain of nasal obstruction, rhinorrhea and unilateral epistaxis-Current s 2nd/ed p 289

There is coincidental malignancy elsewhere in the upper respiratory tract in about 4% ofthe cases and malignant transformation of the tumor occurs in about 8% cases.

Treatment is adequate local excision. If it arises in maxillary sinus, then a medical maxillectomy is surgery of chace. If it arises in the ethmoidal sinus, an external ethmoidectomy is done. If it arises from nose, treatment is wide surgical excision by lateral rhinotomy.

It has a tendency to recur even after removal.
