F2 E-cadherine for invasive 图2 浸润癌E-cadherin染色
F3 P120 for insitu ca 图3 原位癌P120染色
F4. P120 for invasive ca 图4 浸润癌P120染色
Ductal ca (or normal ducts): memberane stain for both e-cad and p120
Lobular lesion: Absence of stain for E-cad and strong cytoplasmic stain for p120.
导管癌(或正常导管): E-cadherin和p120均呈膜阳性。
小叶病变:E-cadherin不着色,p120胞浆强阳性。

Dual stains: anti-ecad labeling with brown color, anti-p120 with pink color, mixed stain, one procedure.
F 1 for insi tu ca
F2 for invasive ca
F3 in situ and normal ducts.
E-cad membrane stain (brown)
P-120 cytoplasmic stain (pink)
Lobular lesion will not see brown color and only pick.
Fig 3: some normal ducts show brown membrane stain and no pink color.
So you know the nature of the lesions.
Lobular carcinoma in situ and invasive lobular carcinoma.
Now, what type of invasive lobular carcinoma is it?

免疫组化双标记:抗E-cadherin棕色,抗p120粉红色。
图1 原位癌
图2 浸润癌
图3 原位癌和正常导管。E-cadherin呈膜阳性(棕色),P-120呈胞浆阳性(粉红色)
小叶病变不见棕色,只有粉红色。正常导管示棕色的膜染色,没有粉红色。
因此你明白病变的性质了:小叶原位癌和浸润性小叶癌。
那么,是什么亚型的浸润性小叶癌呢?

pleomorphic variant?
Some invasive lobular carcinomas consist entirely or in part of cells larger than cells in classical invasive lobular carcinoma with relatively abundant, eosinophilic cytoplasm (Fig. 32.17). The nucleus in some examples is hyperchromatic and eccentric with a distinct nucleolus creating a plasmacytoid appearance (Fig. 32.18). These cells have been referred to variously as myoid (12), histiocytoid (77-79), and pleomorphic lobular carcinoma (80,81) (Figs. 32.18-19). __from Rosen's Breat Pathology (P700)

先复习浸润性小叶癌的分型,再回答问题。
先描述一下浸润性小叶癌(ILC)的细胞形态特点:
A、经典型的细胞特点:多为黏附性差(即松散)的圆形卵圆形小细胞,浆少,核偏位,圆形,核仁不明显,核分裂少,可见胞浆内小管腔。
B、多形性小叶癌细胞:浆细胞样、黏液印戒样、组织细胞样或大汗腺样分化等。
ILC分为:
1、经典型:具有ILC经典型特征的瘤细胞,成列兵样、靶环状、单个散在浸润在间质纤维组织中,>90%伴LCIS.
2、变型,WHO 在变型中提出四个亚型:
1)、腺泡型至少20个以上的具有ILC经典型特征的瘤细胞成团状、簇状聚集,浸润间质。
2)、实性型:具有ILC经典型特征的瘤细胞弥漫成片浸润间质,多形性较经典型明显,核分裂较多,间质纤维组织少。
3)、多形型:保持小叶癌的生长方式,非典型性和多形性更明显。常出现多形性小叶癌细胞。
4)、混合型:有经典型和一种或一种以上的亚型复合组成。
只有80%以上区域表现某一形态特点的病例才能归为某一特殊类型。

It is possible that it is invasive ductal carcinoma and solid DCIS; I would guess that it is LCIS with invasive lobular carcinoma (pleomorphic type). Thanks. Looking forward to hearing the discussion and final answer.
(abin译:这例可能是浸润性导管癌和实性DCIS。我猜也可能是LCIS伴浸润性小叶癌(多形性亚型)。谢谢。期待听到讨论和最终结果。)

Good analysis. H&E slides are good enough to know the of insitu and invasive carcinoma. The key for this case is the nature of the tumor. I will take some photos when I have time. You can continue to guess. |
分析的好,HE切片足以识别原位癌和浸润癌,这个病例的关键是肿瘤的特性,有时间时,我会采一些图片,
大家继续讨论
