Neurilemmomas (schwannomas) are solitary neurogenic tumors that arise from cells of the neural sheath. They are slow growing and represent a proliferation of Schwann cells. Extracranial neurogenic tumors of the head and neck are uncommon, with benign tumors occurring with greater frequency than malignant tumors. These tumors often mimic primary or metastatic disease in the head and neck. Schwannoma of the salivary gland is a particularly rare form of an extracranial neurogenic tumor, with most presenting in the parotid gland originating from a peripheral branch of the facial nerve. An unusual case of neurilemmoma of the submandibular gland is presented, and the literature concerning this subject is reviewed. We believe this tumor originated in an autonomic nerve of the submandibular gland. The mass was discrete and well demonstrated on CT scan. Total excision of the gland resulted in complete resolution of symptoms with no cranial nerve deficits.
神经鞘瘤是起源于神经鞘细胞的孤立性神经源性肿瘤。它们生长缓慢，是施万细胞的增殖。头颈部颅外神经源性肿瘤并不常见，良性肿瘤的发生率高于恶性肿瘤。这些肿瘤常酷似头颈部的原发性或转移性疾病。涎腺神经鞘瘤是颅外神经源性肿瘤中一种特别罕见的类型，大多数发生于腮腺，起源于面神经的外周分支。本文报告一例罕见的下颌下腺神经鞘瘤病例，并复习有关该主题的文献。我们认为该肿瘤起源于下颌下腺的自主神经。肿块边界清晰，CT扫描显示良好。腺体全切术后症状完全缓解，无颅神经功能缺损。
