Schwannomas (neurilemmomas) are slow-growing, benign neoplasms derived from schwann cells, the sheath cells that cover myelinated nerve fibers. These tumors most commonly arise in the soft tissues of the head and neck, as well as on the flexor surfaces of the upper and lower extremities. Intraoral lesions are uncommon, however, and intraosseous schwannomas are even rarer. In the Mayo Clinic series of 11,087 primary bone tumors, 14 cases of intraosseous schwannoma were identified, accounting for less than 1% of these benign primary bone tumors. The most common site of occurrence is the mandible, a characteristic traditionally attributed to the long intraosseous path of the inferior alveolar nerve. In this article, we describe an additional case occurring in the mandible of a 15-year-old boy.
施万细胞瘤（神经鞘瘤）是一种生长缓慢的良性肿瘤，由施万细胞衍生而来，施万细胞是覆盖有髓神经纤维的鞘细胞。这些肿瘤最常见于头颈部软组织以及上肢和下肢的屈侧表面。然而，口腔内病变并不常见，骨内施万细胞瘤则更为罕见。在梅奥诊所的11087例原发性骨肿瘤系列中，共识别出14例骨内施万细胞瘤，占这些良性原发性骨肿瘤的比例不到1%。最常见的发生部位是下颌骨，这一特征传统上归因于下牙槽神经较长的骨内走行路径。在本文中，我们描述了一名15岁男孩下颌骨发生的另一例病例。
