摘要
目的 :研究促结缔组织增生性成釉细胞瘤的临床病理特点。方法 :对 13例促结缔组织增生性成釉细胞瘤进行临床病理研究及病例随访。结果 :13例中女多于男 (1.2∶1) ,平均年龄 45岁 ,上下颌之比为 1∶1.2。病变主要位于前牙区和 /或前磨牙 (77% )。X线表现通常为透射影、阻射影混存。镜下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的一种新的类型 ,具有特征性病理表现及低复发率。
Objective:To investigate the clinicopathologic characteristics of the desmoplastic ameloblastoma.Methods:13 cases of desmoplastic ameloblasioma were histopathologically analysed and followed up.Results:Among the 13 cases,7 were females and 6 were meles(1.2∶1);the average age was 45 years old;the ratio or the maxillary and mandible is 1∶1.2.The lesions were mostly located in the anterior position or premolar region of the maxilla and mandible ,which exhibited radiographically a mixed radiolucent-radiopaque appearance.Typical microscopic features consist of islands of ameloblastoma within dense,sometimes hyalinized,fibrous connective tissue stroma.Epithelial islands or strands are often irregular and compressd.Conclusion:The desmoplastic ameloblastoma is a new type of ameloblastoma,which has characteristic in clinicopathology and lower recurrence rates.
