【摘要】 目的 :分析单囊型成釉细胞瘤的临床病理特点。方法 :对 2 4例单囊型成釉细胞瘤行HE染色及组织学观察。结果 :2 4例中 ,男性 13例 ,女性 11例 ;平均年龄 2 9.2岁 ;下颌 2 3例 ,上颌 1例。X线片示呈单囊性边界清楚透光区。病理表现分三型 :(1)腔内型 (丛状单囊成釉细胞瘤 ) 7例 ,(2 )壁内型 (壁成釉细胞瘤 ) 10例 ,(3)混合型 7例 ,未见WHO第一型牙源性囊肿早期成釉细胞瘤变。结论 :单囊型成釉细胞瘤的临床和X线表现无特征性 ,其确诊主要依靠组织病理学。更多还原

【Abstract】 Objective:To investigate clinicopathological characteristics of unicystic ameloblastoma. Methods:HE staining and histopathological observation. Results:Among the 24 cases, 13 were males and 11 were females; the average age were 29.2 years old; The ratio of the maxilla and mandible is 1:23. Radiographically, the lesions were unilocular radio translucent and well-demarcated. They were divided histologically into 3 subtypes. 7 cases were intracavity variety, sometimes referred to as plexiform unicystic ameloblastoma; 10 cases were intramural variety, sometimes referred to as mural ameloblastoma; 7 cases were mixture variety; the first variant in WHO, sometimes referred to as the early neoplasia from odontogenic cyst, was not seen. Conclusion:The diagnosis of unicysticameloblastoma is made histologically, and cannot be predicted preoperatively on clinical or radiographic grounds. [更多还原
