摘要 目的探讨附睾腺瘤样瘤的临床病理特点以及鉴别诊断,并结合免疫组结果临床病理分析。方法分析9例附睾腺瘤样瘤的大体、镜下特点并进行免疫组化染色,并进行讨论。结果9例附睾腺瘤样瘤直径0.5~5.9cm,形态学观察可见肿瘤细胞形成细小腔隙或腺样结构,内衬扁平或立方上皮,并不同程度地伴有平滑肌组织增生;免疫组化染色显示衬覆上皮Calretinin、MC及AE1/AE3、Vimentin阳性,EMA有5例阳性表达(55.6%),SMA、CEA、CD34、LCA、S-100、NF等均阴性,腺瘤样瘤须与血管瘤、平滑肌瘤、转移癌以及神经纤维瘤等进行鉴别。结论腺瘤样瘤不常见,好发于男性或女性生殖系统,临床检查均易误诊和漏诊,免疫组化支持其为间皮来源肿瘤,生物学行为良性,预后良好。
