目的 总结促结缔组织增生性成釉细胞瘤的X线特点。方法 对病理确诊的 15例促结缔组织增生性成釉细胞瘤的X线表现进行回顾性分析 ,并与一般型成釉细胞瘤对比观察。结果促结缔组织增生性成釉细胞瘤主要位于前牙区和 (或 )前磨牙区 (13/ 15 )。X线有 3种表现 :①单房改变 (7/ 13) ,病变范围小且有密度不均小片状或条索状影像 ;②多房性皂泡状改变 (2 / 13) ,肿瘤内有较多致密条纹样直线或不规则状骨隔 ;③混合性改变 (4 / 13) ,病变区内可见似丛状增生团块 ,边缘带伴有单囊状改变。该瘤组织学上以大量增生的纤维结缔组织间质中散在不规则、压缩状上皮岛或条索为特点。结论 促结缔组织增生性成釉细胞瘤为成釉细胞瘤一种新的类型 ,具有特征性X线和组织学表现 ,X线方面应与骨化性纤维瘤和牙源性粘液瘤等鉴别
Objective To summarize the X-ray features of connective tissue proliferative ameloblastoma. Methods The pathological findings of 15 cases of connective tissue proliferative ameloblastoma X-ray findings were retrospectively analyzed and compared with the general ameloblastoma. Results The most common connective tissue proliferative ameloblastoma mainly located in the anterior and / or anterior premolars (13/15). X-ray has 3 kinds of performance: ① single room change (7/13), small lesions and uneven density patchy or cord-like image; ② polycystic soap bubble change (2/13), within the tumor There are more dense stripe-like linear or irregular bone septum; ③ mixed changes (4/13), the lesion can be seen like plexiform hyperplasia, with a single cystic edge changes. Histologically, the tumor is characterized by loosely packed, compressed epithelial islands or cords in a large number of hyperplastic fibrous connective tissue interstitium. Conclusions The proliferative ameloblastoma of connective tissue is a new type of ameloblastoma with characteristic X-ray and histological manifestations. X-ray should be differentiated from ossifying fibroids and odontogenic myxomas
