Inverted Papilloma Completely Obstructing Anterior Nasal Orifice

Area of Science:

• Otolaryngology
• Pathology

Background:

• Sinonasal inverted papilloma is a benign neoplasm originating in the nasal cavity and paranasal sinuses.
• Different histological types, including fungiform, inverted, and cylindrical papillomas, have distinct typical locations of origin within the sinonasal tract.

Observation:

• This report details an exceptionally rare presentation of an inverted papilloma.
• The lesion was observed to cause complete obstruction of the anterior nasal orifice.

Findings:

• The study documents a unique case of inverted papilloma.
• The tumor's location led to a complete blockage of the anterior nasal opening.

Implications:

• This case expands the understanding of sinonasal inverted papilloma's potential clinical manifestations.
• Recognizing rare obstructive presentations is crucial for accurate diagnosis and timely management of sinonasal lesions.
