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.
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.
Histopathological examination and immunohistochemical staining confirmed a neurilemmoma.
The mass was completely removed via an intranasal approach.
Neurilemmoma is easy to overlook because it occurs rarely in the nasal vestibule, but neurilemmoma needs to be considered as a differential diagnosis.
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。
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。
组织病理学检查和免疫组织化学染色证实为神经鞘瘤。
经鼻内镜下完整切除肿瘤。
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。
