颌骨中心性粘液表皮样癌临床、X线、病理学研究

Central mucoepidermoid carcinoma of the jaws a clinical,radiologic,and pathological study

目的 对 11例罕见的颌骨中心性粘液表皮癌 (CMCJ)的临床资料 ,X线表现和病理特征进行分析研究。在国内首次提出CMCJ的X线特征分型 ,以期为临床提供帮助。方法 对 1975年～ 1999年间 11例经病理确诊的CMCJ的临床表现、影像学特征、组织病理改变进行分析研究。结果 11例CMCJX线分五型 :①多囊型 ;②单囊形 ;③骨质破坏型 ;④“火焰”状型 ;⑤发生在上颌骨CMCJ由于上颌窦的存在 ,表现复杂。结论 CMCJ的X线表现非常复杂 ,X线分型有助于对CMCJ治疗、预后提供依据。

Objective This study evaluated the clinical data,radiological and pathological of 11 rare central mucoepidermoid carcinoma of jaws(CMCJ) and defined the types of radiological presentation as CMCJ. Methods 11 cases between 1975 and 1999 with the diagnosed pathologically as CMCJ were analysed in terms of clinic data,radiographic images,histopathology and treatment. Results CMCJ in 11 cases were classifed in five types:multicystic type;unicystic type;osteolytic type;“flame shape'type.In the maxilla where the tumor can spread to the maxillary antrum,it produces more complex presentation. Conclusion CMCJ produces more complex presentation.We consider that the radiographic classification is useful in considering the treatment method and the prognosis of the CMCJ.Defined the types of radiological presentation of the CMCJ is connected with tumor malignant degree.
