发生于软组织的造釉细胞瘤是罕见的。近来有学者建议将骨外和骨内这两种造釉细胞瘤加以区别,以澄清诊断和治疗上的混淆。因此,作者认为有必要籍助光镜和超微结构表现来证明下述病例。作者报告一例43岁白人妇女,全口无牙,左上颌结节牙槽粘膜上有一增殖块。病变外突并具疣样外形,无其它症状,无过去的医疗史。X线摄片未显示该区域骨质受系。病变全部切除后,30个月内无复发。手
Ameloblastomas that occur in soft tissues are rare. Recently, some scholars have proposed to distinguish the two types of ameloblastomas, extraosseous and intraosseous, to clarify the confusion in diagnosis and treatment. Therefore, the author believes that it is necessary to prove the following cases with light microscopy and ultrastructural performance. The authors report a case of a 43-year-old Caucasian woman who had no teeth at all, and a proliferation block on the alveolar mucosa of the left maxillary tubercle. The lesions protrude outwardly and have a scallop-like appearance, no other symptoms, and no past medical history. Radiographs do not show bone resorption in this region. After resection of the lesion, there was no recurrence within 30 months. hand
