RATIONALE
Neurofibroma (NF) is the most common benign peripheral nerve sheath tumour that most often occurs as a solitary tumour. A clinical and imaging diagnosis may be challenging since no distinctive features are unique for this lesion. Solitary NFs are treated by complete resection that may sometimes require a nerve sacrifice, ending with a neurological deficit.
PATIENT CONCERNS
A 5-year-old girl with mild asymptomatic slow-growing swelling in the vestibulum of her right mandible.
DIAGNOSIS
A solitary variant of extraosseous NF involving the right mental branch of the inferior alveolar nerve.
TREATMENT
Surgical removal of the lesion while fully preserving the mental branch.
OUTCOMES
No sensory deficit was identified during a 3-month follow-up.
TAKE-AWAY LESSONS: Ultrasonography is a valuable tool for evaluating soft-tissue masses of the oral cavity. A solitary extraosseous NF involving the mental branch can be surgically removed without nerve deficit.
理论依据
神经纤维瘤（NF）是最常见的良性周围神经鞘瘤，多表现为孤立性肿瘤。由于该病变没有独特的特征，临床和影像学诊断可能具有挑战性。孤立性神经纤维瘤通过完整切除进行治疗，有时可能需要牺牲神经，最终导致神经功能缺损。
患者情况
一名5岁女孩，右下颌前庭出现轻度无症状的缓慢生长肿胀。
诊断
累及下牙槽神经右颏神经分支的骨外神经纤维瘤孤立变异型。
治疗
手术切除病变，同时充分保留颏神经分支。
结果
在3个月的随访中未发现感觉功能缺损。
经验教训
超声检查是评估口腔软组织肿块的重要工具。累及颏神经分支的孤立性骨外神经纤维瘤可以通过手术切除而不出现神经功能缺损。
