Schwannomas are neurogenic neoplasms rarely found in the sinonasal tract, where localization to the nasal septum is exceedingly rare (only 11 cases have been described in the western literature). We report the case of a 29-year-old white male with a schwannoma completely filling the left nasal fossa and arising from the bony part of the septum. A computer tomography (CT) scan and a biopsy suggestive of benign schwannoma were obtained before the lesion was removed by a degloving approach. The preoperative diagnosis of nasal septum schwannoma was confirmed. The patient is asymptomatic and without endoscopic evidence of recurrence 7 years after surgery. A review of the literature with particular emphasis on the clinical presentation, histological features, differential diagnosis and therapeutic options for such a rare lesion is included.
施万细胞瘤是一种神经源性肿瘤，很少见于鼻窦，而位于鼻中隔的情况极为罕见（西方文献中仅描述过11例）。我们报告一例29岁白人男性患者，其施万细胞瘤完全充填左侧鼻窝，起源于鼻中隔的骨质部分。在通过掀翻术切除病变之前，进行了计算机断层扫描（CT）并活检，提示为良性施万细胞瘤。术前诊断的鼻中隔施万细胞瘤得到证实。患者无症状，术后7年无内镜下复发迹象。本文还对文献进行了综述，特别强调了这种罕见病变的临床表现、组织学特征、鉴别诊断和治疗选择。
