姓 名: | ××× | 性别: | 女 | 年龄: | 31岁 |
标本名称: | 大网膜 | ||||
简要病史: | 女31,下腹痛13天,加剧2天。于2004年8月23日入院。 | ||||
肉眼检查: | 术中见淡黄色腹水500ml,腹膜尚光滑,大网膜明显增厚,表面粟粒状,大网膜与横结肠融合成团,与膀胱反折腹膜粘连。子宫直肠凹及小网膜表面见细小粟粒状结节。子宫双附件表面无异常。肝、脾、胃表面无结节,无肿块。切除横结肠以下饼状大网膜。病理大体检查:僵硬大网膜组织约24*15*2cm,表面及切面见多数灰白结节,结节0.1-1cm,切面灰白色,质地较硬。 |
这个病史是我翻阅病历后整理出来的,图片也是我自己拍摄的。图8-10,13-14为油镜。

今天翻阅了病历,并复习了HE图片和免疫组化。主要更正:
1、术前6个月多(2004年1月,春节前)有“盆腔炎”住院治疗并“缓解”史,首次发作到死亡时间约1年;
2、免疫组化:
上皮标记:CK、CK18、EMA弥漫强阳性(可见刷状缘);Vimentin弥漫阳性。提示双相分化。
间皮标记:Calretinin散在阳性,Mes阴性,HBME-1和CK5/6未检测。提示可疑间皮分化。
激素及受体:HCG阳性(与此一致,血HCG轻度升高),HPL和PLAP可疑阳性;ER和PR未检测。提示可疑中间滋养细胞分化。
血管(内皮)标记:F-Ⅷ- CD34- CD31-
其他标记:S100、HMB45、α-inhibin、p63、E-Cadherin、EGFR均阴性,Ki67阳性细胞数<10%。
3、电镜未见微绒毛(石蜡组织做的电镜,但我们没有看到电镜照片)

以下是引用fangg 在2007-2-28 17:04:00的发言:
abin,这例我们开始也诊断为间皮细胞增生伴蜕膜样变。没有认为其为肿瘤,因为前三图片中蜕膜样变的大细胞均位于脂肪组织周围纤维组织间隔内,这种现象在间皮瘤内应该是少见的。 而患者术后快速死亡我们认为与并发症有关系,而不是肿瘤性死亡。 但看了你这篇文献,感到很有收获,没有查阅相关文献,所以有个疑问想请教:假肿瘤样蜕膜病与恶性蜕膜样间皮瘤有没有组织学上的鉴别点? |
