Abstract
Solitary fibrous tumors (SFTs) are rare neoplasms primarily found in the pleural region but have been documented in diverse extrapleural sites, including the nasal cavity and paranasal sinuses, albeit infrequently. Here, we present a case of a 48-year-old female who presented with a right-sided nasal mass and associated ophthalmologic symptoms, ultimately diagnosed with a benign spindle cell lesion localized to the nasal cavity. The patient underwent a comprehensive evaluation involving clinical examination, radiological imaging, and histopathological analysis, leading to the identification of a benign solitary fibrous tumor. Notably, diagnosing SFTs in the nasal cavity presents challenges due to their nonspecific clinical and imaging features, necessitating a multidisciplinary approach for accurate diagnosis and optimal management. Surgical excision, preferably via endoscopic techniques, remains the cornerstone of treatment based on tumor characteristics and extent. This case underscores the importance of recognizing uncommon presentations of sinonasal lesions, navigating diagnostic complexities, and emphasizing the critical role of multidisciplinary collaboration in achieving favorable treatment outcomes for patients with such nasal cavity tumors.
