1、前列腺非典型腺瘤样增生12例病理形态学观察赵红艳,叶明福,王亚丽,汤金梁,陈锐(第三军医大学新桥医院病理科,重庆400037)[摘要]目的探讨前列腺非典型腺瘤样增生(AAH)的病理形态学特征和鉴别诊断。方法收集AAH标本12例,应用光镜、免疫组化EliVisionTMPlus二步法,选择34βE12、P63、P504S、PSA、PSAP抗体检测,观察其病理形态学特点和免疫组化表达特点。结果12例前列腺非典型腺瘤样增生均来自于临床诊断为良性前列腺增生的前列腺手术切除标本,经进一步病理检查发现包含有AAH病灶,12例腺泡均呈结节状增生,增生的腺泡排列紊乱、结构完整,基底细胞难以辨别,需要与
2、高分化腺癌的腺泡鉴别;8例由大小基本一致的中小腺泡构成,4例增生的腺泡大小不均,11例腺泡呈低乳头状结构;12例中5例伴有前列腺萎缩后增生(PAH)。免疫组化显示,增生的腺泡边缘均有34bE12或p63阳性反应,P504S均显阴性;其中5例基底细胞基本完整,7例基底细胞断续存在。结论AAH是较少见的前列腺瘤样病变,在HE切片中,易误诊为前列腺高分化腺癌。基底细胞标记物34bE12、p63和癌性上皮标记物P504S联合应用对AAH的诊断具有实际应用价值。[关键词]前列腺非典型腺瘤样增生;病理学;免疫组化染色Studyonthebasalcellsof11postatrophichyper
