子宫内膜非典型性息肉样腺肌瘤11例临床病理分析

目的 探讨子宫内膜非典型性息肉样腺肌瘤(APA)的临床病理特点,以期提高对其诊断,鉴别诊断和治疗水平.方法 对11例APA进行组织病理学观察,部分辅以免疫表型分析,结合临床资料并复习相关文献.结果 患者平均年龄45岁,其中9例发生于绝经前.临床主要表现为宫腔占位,宫颈内口赘生物和不规则阴道出血.光镜下肿瘤呈纤维肌性间质中出现腺上皮细胞轻度到非常明显非典型性及结构复杂的子宫内膜样腺体.免疫表型:间质细胞SMA弥漫强阳性表达,desmin局灶阳性,CD10局灶阳性;腺上皮及间质细胞ER、PR均强阳性;Ki-67少量散在阳性表达,p53阴性.维多利亚蓝染色:间质胶原纤维红色,弹力纤维蓝色,平滑肌纤维黄色.随访6例患者均预后良好.结论 APA是一种罕见的子宫上皮和间叶混合性肿瘤,病理诊断主要依靠组织病理和免疫组化抗体标记.须与高分化子宫内膜样腺癌、恶性Mtillerian混合瘤、腺纤维瘤和腺肉瘤、子宫内膜息肉等鉴别.病变彻底切除是治疗APA的主要手段.
