# Solitary fibrous tumor of the nasal septum: a case report and literature review

## TL;DR

A rare case of a nasal septum tumor was successfully treated with endoscopic surgery and showed no recurrence after two years.

## Contribution

This case report adds to the limited literature on nasal solitary fibrous tumors and demonstrates the efficacy of endoscopic resection.

## Key findings

- The tumor was successfully removed via endonasal endoscopic surgery.
- Histopathology confirmed the diagnosis with CD34 and CD99 positivity.
- The patient remained recurrence-free for 2 years post-surgery.

## Abstract

Solitary fibrous tumors (SFT) are rare spindle cell neoplasms of mesenchymal origin, typically occurring in the pleura, with extra-pleural manifestations being uncommon. SFTs of the nasal cavity are particularly rare, with limited cases documented in the literature. This report presents the case of a 62-year-old female with a solitary fibrous tumor arising from the nasal septum. The patient presented with a unilateral nasal mass, obstruction, and nasal discharge, which did not improve with antibiotics. The tumor was successfully excised via an endonasal endoscopic approach, and histopathological analysis confirmed the diagnosis of an SFT with positive CD34 and CD99 markers. The patient remained symptom-free with no recurrence over 2 years of follow-up. This case highlights the importance of considering SFTs in the differential diagnosis of nasal masses and underscores the effectiveness of endonasal endoscopic resection as a minimally invasive treatment approach.
