摘要 目的探讨牙源性腺样瘤(AOT)的临床病理特征。方法收集4例AOT患者临床病理资料,进行病理组织形态观察和免疫表型分析,并结合文献综合讨论。结果4例AOT发病年龄15~34岁,中位年龄23岁;男3例,女1例;发病部位均为右上颌骨,临床主要表现为上颌骨无痛性肿块或局部膨隆肿胀,影像学表现为单囊性圆形或类圆形低密度影;光镜下见肿瘤组织呈玫瑰花瓣样、腺管样、小梁状或筛状排列,瘤细胞立方状或高柱状,细胞间可见嗜酸性均质无结构物和球状钙化小体;肿瘤细胞CK和P63弥漫强阳性,筛状结构表达Vimentin,Ki-67增殖指数1%~5%。结论AOT是一种少见的牙源性良性肿瘤,具有独特的临床及病理学特征,确诊主要依靠病理学检查。
