Schwannomas are slowly growing tumours derived from Schwann cells. We present a clinical case of schwannoma in the mandibular angle.
Case report and a review of the world literature concerning intraosseous schwannoma of the maxillofacial region.
Schwannomas or neurilemmomas are slow-growing, benign neoplasms derived from Schwann cells. Intraoral lesions are unusual and intraosseous schwannomas are even rarer, representing less than 1 per cent of benign primary tumours of the bones. We present a clinical case of schwannoma in the mandibular angle mimicking a keratocystic odontogenic tumour, with a complicated posterior evolution.
Clinically, neurilemmomas are slow-growing tumours which may be present for years before becoming symptomatic. Radiographically, the image may be suggestive of a benign process such as an odontogenic keratocyst. Histological analysis of the specimens obtained is extremely important in order to establish the final diagnosis.
施万细胞瘤是起源于施万细胞的缓慢生长的肿瘤。我们报告一例下颌角施万细胞瘤的临床病例。
病例报告并回顾世界范围内有关颌面部骨内施万细胞瘤的文献。
施万细胞瘤或神经鞘瘤是起源于施万细胞的生长缓慢的良性肿瘤。口腔内病变不常见，骨内施万细胞瘤更为罕见，占原发性骨良性肿瘤的比例不到1%。我们报告一例下颌角施万细胞瘤的临床病例，该病例酷似牙源性角化囊性瘤，后期病情复杂。
临床上，神经鞘瘤生长缓慢，可能在出现症状前已存在数年。影像学上，其表现可能提示为良性病变，如牙源性角化囊肿。为明确最终诊断，对所取标本进行组织学分析极为重要。
