Inverted Papilloma: A Rare Tumor of the Nasal Cavity

Introduction

Inverted papilloma is a benign tumor that arises from the lining of the nasal cavity and paranasal sinuses. Although it is not cancer, it is considered locally aggressive and has the potential to recur if not completely removed.

In some cases, inverted papilloma may be associated with malignant transformation.

Symptoms

Symptoms often resemble chronic sinus disease and may include:

• Nasal obstruction

• Nasal discharge

• Recurrent sinus infections

• Reduced sense of smell

• Occasional nosebleeds

Many patients experience symptoms on one side of the nose, which can be an important diagnostic clue.

Diagnosis

Diagnosis usually involves:

• Nasal endoscopy

• CT or MRI imaging

• Biopsy of the tumor

Imaging studies help determine the extent of the tumor and guide surgical planning.

Treatment

The primary treatment for inverted papilloma is surgical removal.

Modern treatment is typically performed using endoscopic sinus surgery, which allows surgeons to remove the tumor through the nasal passages without external incisions.

Complete removal is important because incomplete surgery may lead to recurrence.

Follow-Up

Patients usually require long-term follow-up with periodic nasal endoscopy because recurrence may occur even years after surgery.
