颌骨骨肉瘤临床与病理研究

目的：总结颌骨骨肉瘤临床、病理特点。方法：对32例颌骨骨肉瘤的临床表现、x线影象及病理特征等进行回顾性分析。结果：32例中男14例，女18例，平均年龄36．9岁；病变位于下颌骨20例，上颌骨12例；临床多以颜面部肿胀伴皮肤麻木和牙痛就诊，x线主要表现为境界不清的骨破坏区；镜下均可见到肿瘤性成骨，并可分为骨母细胞型（13例）、软骨母细胞型（11例）和纤维母细胞型（8例）3种类型。获得随访15例，其中死亡2例，均为骨母细胞型骨肉瘤患者，分别发生于上颌窦和下颌骨升支。结论：肿瘤性成骨是病理诊断重要依据；颌骨骨肉瘤发病年龄较晚，其预后较好，但发生于上颌窦、下颌升支的骨母细胞型骨肉瘤预后相对较差。
