INTRANASAL PLEOMORPHIC ADENOMA ARISING FROM THE LATERAL NASAL WALL

Area of Science:

• Otolaryngology
• Pathology

Background:

• Pleomorphic adenoma (PA) is a benign salivary gland neoplasm.
• PA is uncommon in the sinonasal region, typically occurring on the nasal septum or lateral nasal wall.

Observation:

• A 72-year-old woman presented with progressive right-sided nasal obstruction.
• Examination revealed a 2 cm, mucosa-covered mass in the right nasal cavity with a broad base on the lateral nasal wall.
• CT scan confirmed a solid soft tissue mass attached to the lateral nasal wall, anterior to the inferior turbinate.

Findings:

• Histological diagnosis confirmed pleomorphic adenoma of minor salivary glands.
• The tumor was completely excised via endonasal endoscopic surgery.
• No recurrence was observed during a 6-year follow-up period.

Implications:

• This case represents an extremely rare presentation of intranasal pleomorphic adenoma.
• The successful surgical management and long-term follow-up demonstrate effective treatment for this rare condition.
• Further documentation of such rare sinonasal tumors is valuable for understanding their behavior and optimizing treatment strategies.
