RATIONALE
Neurilemmoma is a benign tumor derived from the Schwann cells of the nerve sheath. The highest incidence of neurilemmoma occurs in the head and neck region; however, the nose and paranasal sinuses are rarely involved. Less than 4% of these tumors involve the nasal cavity and paranasal sinuses. To date, only six cases of nasal vestibule neurilemmoma have been reported.
PATIENT CONCERNS
Two patients (a 32-year-old man and a 42-year-old woman) visited our clinic with complaint of a lump in the left nasal vestibule.
DIAGNOSIS
Histopathological examination and immunohistochemical staining confirmed a neurilemmoma.
INTERVENTIONS
The mass was completely removed via an intranasal approach.
OUTCOMES AND LESSONS
Neurilemmoma is easy to overlook because it occurs rarely in the nasal vestibule, but neurilemmoma needs to be considered as a differential diagnosis.
背景
神经鞘瘤是一种来源于神经鞘 Schwann 细胞的良性肿瘤。神经鞘瘤的最高发病率发生在头颈部；然而，鼻腔和副鼻窦很少受累。这些肿瘤中只有不到 4%累及鼻腔和副鼻窦。迄今为止，仅报道了 6 例发生于鼻前庭的神经鞘瘤。
病例报告
两名患者（一名 32 岁男性和一名 42 岁女性）因左侧鼻前庭肿块就诊于我科。
诊断
组织病理学检查和免疫组织化学染色证实为神经鞘瘤。
治疗
经鼻内镜下完整切除肿瘤。
结果和结论
神经鞘瘤在鼻前庭很少见，容易被忽视，但需要将其作为鉴别诊断的考虑因素。
