16 岁女左卵巢肿物8厘米,HE图如上,鉴别诊断和应什么做免疫?
江庆萍
首先考虑幼年颗
任永昌山东临沂中心医院
这例异型性太大,核仁明显,横肉和恶性横纹肌样瘤要鉴别。
胡顺则@湖北妇幼保健院
JGCT
赵亚娟
加个鉴别:无性细胞瘤
杨鹏 淄博市妇幼保健院
高血钙型小细胞癌
胡顺则@湖北妇幼保健院
鉴别:恶黑;小细胞癌;生殖细胞肿瘤(胚胎性癌)
郭燕 南通肿瘤
@杨鹏 淄博市妇幼保健院 年龄
杨鹏 淄博市妇幼保健院
@郭燕 南通肿瘤 16,无性细胞瘤也在鉴别之内。
赵澄泉UPM
我想听听大家都需做那些染色?
胡顺则@湖北妇幼保健院
IHC:inhibit-r,calretinin,melan_a,wt_1,cd99,ema,ck7,

@杨鹏 淄博市妇幼保健院 16岁,小细胞癌的话就大跌眼镜了啦,生殖,性索放首位考虑
薄冰之旅
在加上cd56 cd10 ,颗粒可以很好的cd56阳性

1.低倍镜下:囊实性结构。囊性部分,内衬多层细胞。囊内容物为嗜酸性液体;实性部分,弥漫性,中间有纤维间隔和粘液变性。
2.高倍镜下:细胞为小圆形,核偏位,胞浆嗜酸。核圆形,核膜厚,泡状核,核仁明显。核分裂多。坏死图片上没见到。有凋亡小体。
3.间质为透明变性的纤维间质。
结合年龄须考虑:
①JGCT
②高钙血症的小细胞癌。
③腺泡状横纹肌肉瘤。
④横纹肌样瘤。
⑤恶黑。
⑥恶性间皮瘤
4.IHC :Inhibin Calretinin WT-1 SF 1 CD 99 CD56 S-100,HMB 45 MyoD1 ,NES ,CK-pan ,神经内分泌标记Syn CG-A 。

@景晓峰 无性没加上?
景晓峰
@杨鹏 淄博市妇幼保健院 老师,我不考虑生殖细胞肿瘤。淋巴造血系统,DLBCL 伴浆细胞分化,粒细胞肉瘤(绿色瘤)放在二线。

16岁的孩子,需要常规考虑的4种淋巴瘤,形态上都不符合……

SCCOHT is a rare tumour,with less than 500 cases reported in the world literature.Until 2014,little was known of its etiology,and its rarity made it difficult to study from an epidemiological perspective.As a tumour,SCCOHT has several notable features.Firstly,it affects young females;the youngest reported patient is 14 months[1]and the mean age at diagnosis is approximately 25 years[2].Secondly,it is associated with a very poor outcome;even in early-stage disease only about one-third of affected women survive 5 years.Our recent analysis of all available cases[3]suggests that if treatment can prevent relapse within 5 years of diagnosis,then cure is very likely.Thirdly,SCCOHT is associated with hypercalcemia in approximately two thirds of cases[2].
The histological features are typically of a relatively monotonous population of tumour cells with various architectural patterns set in a generally inconspicuous stroma[4].There is usually predominantly a diffuse sheeted architecture but the neoplastic cells also occasionally growin nests,cords or trabeculae.Follicle-like structures containing eosinophilic,or more uncommonly basophilic,fluid are present in most cases(Fig.1a);these are a characteristic histological feature but are not pathognomonic since they are seen in some other neoplasms which are in the differential of SCCOHT[2,4].The tumour cells usually have minimal cytoplasm resulting in a“small round blue cell”appearance.In approximately 40%of cases,a variably prominent component of large cells with abundant eosinophilic cytoplasm is present.The large cells typically contain abundant glassy eosinophilic cytoplasm with eccentric large pale nuclei with prominent nucleoli,resulting in a rhabdoid appearance[4].When the large cells predominate or are exclusive,the tumour is rather confusingly referred to as the large cell variant of SCCOHT.
地球上有多少人?500例?难怪还没遇到!

@胡余昌-宜昌市中心人民医院-群管 因为有些误诊了。我也没碰到过。

感觉真没见过!@杨鹏 淄博市妇幼保健院

@胡余昌-宜昌市中心人民医院-群管 你淋巴瘤专家,再研究妇科,我们都要丢饭碗了
盐城市第一人民医院赵海鸥
@福建肿瘤阿丹 我也有同感
郭燕 南通肿瘤
@福建肿瘤阿丹 @胡余昌-宜昌市中心人民医院-群管 @杨鹏 淄博市妇幼保健院 确实跟文献中描述的很像,谢谢,见识了

All got the Dx of my case. The Ddx should include germ cell tumors, sex cord tumor. SCCOHC 诊断首先要排除上述,本无什么特别染色,一般上皮染阳性,大多病例WT1 阳,相当比例SALL4 局阳,我见3个病例SALL4都阳,加上形态诊断并不难。最近讲SMARCA4 突变,无表达,具有特异性和敏感性,但我从末用过。本例 OCT3/4, cd117, cd30 inhibin, chromogranin, d2-40, FAP, HNF, pax8, plap, HCG 都阴,calretinin 局阳,EMA 阳,AE1/3 局阳
赵澄泉UPMC
上依次为cam5.2, ki67,SALL4, WT1, synaptophysin.
除了上面汪俊提供的综述,这另一综述和研究原文for SMARCA4. 供有兴趣者阅读。本例形态学真象恶性rhabdoid tumor. 上综述提可能来自germ cell.

我自己还从来没有诊断过一例。通过这个例子也学到了很多!细胞有那种Epithelioid appearance and prominent nucleoli 和传统意义上的小细胞太不一样了!赵教授用了大量时间给大家发照片包括组化及references ,真得是很感谢!@赵澄泉UPMC
