Schwannoma at an Unusual Site: Case Report and Surgical Technique Discussion for Nasal Dorsum.

Peripheral nerve sheath tumors (PNSTs), while uncommon, can have a significant impact on appearance and quality of life, especially when they form in prominent areas such as the nose dorsum. We discuss a case of a 29-year-old woman who developed a benign PNST on the right side of her nasal ala. This tumor gradually grew, impairing her face appearance. Diagnostic tests, such as computed tomography (CT) and magnetic resonance imaging (MRI), revealed the tumor as a slowly growing, well-defined mass. The tumor was removed via open rhinoplasty under general anesthesia, and pathological investigation verified its benign nature. After surgery, the patient's quality of life improved significantly, and there were no evidence of tumor recurrence after eight months. This case emphasizes the need of including PNST in the differential diagnosis of nasal tumors.
