A clinicopathologic review was made of nine cases of benign schwannomas located in the oral cavity. The tumors arose in the vestibule (3 cases), tongue (2 cases), palate (2 cases), floor of the mouth (1 case) and lower lip (1 case). The patients included 5 women and 4 men whose ages ranged from 17 to 75 years (mean: 32.5). No patient developed recurrences. Encapsulated tumors with benign typical histology were evidenced in every case. Positive immunostaining for S-100 protein, Leu 7 antigen, vimentin and glial fibrillary acidic protein (GFAP) supported the schwann cell nature of these tumors.
对9例位于口腔的良性神经鞘瘤进行了临床病理回顾。肿瘤发生于前庭（3例）、舌（2例）、腭（2例）、口底（1例）和下唇（1例）。患者包括5名女性和4名男性，年龄在17至75岁之间（平均：32.5岁）。所有患者均未复发。每例均证实为具有良性典型组织学的包膜肿瘤。S-100蛋白、Leu 7抗原、波形蛋白和胶质纤维酸性蛋白（GFAP）的免疫染色阳性支持了这些肿瘤的施万细胞性质。
