见过大家的回复后,我出了一身冷汗,赶紧倒回科室,拿出切片细细观察.
竟发现这例是一个非常好的病例.
下面请看我的粗浅分析,有什么不对之外,请大家批评指正.

Read your fig carefully.仔细地看了你发的图。
1. LCIS with pagetoid involvement of duct.LCIS伴Paget样累犯导管。
2. DCIS.
3 I am not sure if invasive carcinoma is present based on the morphology and your IHC results. The tumor nests are surrounded by scattered myoepithelial cells (positive SMA and scattered positive p63). I do not think the presence of invasive carinoma. However, in the figure 5, the floor 4 there are some small tubular structures within the stroma in the left of DCIS. I cannot see them in details due to the lower power. You may need to stain this block with myoepithelial markers if you are not sure by H&E.
2 根据你提供的形态学和免疫组化,我不能确定是否存在浸润癌。肿瘤巢围绕着散在的肌上皮细胞(SMA阳性,p63散在阳性)。我认为不存在浸润癌。然而,在第4楼图5,在DCIS左侧间质中有小管状结构。我不能看清细节,因为倍数较低。如果HE不确信,你可能需要将这块组织染肌上皮标记。
The dx of invasive carcinoma is a cretical call. You have to be sure before you sign your case. Reading photos here is totally different from reading the true slides. You can take people's suggestion here as your reference, but cannot make your diagnosis based on suggestion here.
诊断浸润癌是很重要的事,在签发报告前一定要非常确信。在这里看图总体上不同于看切片。你可以把别人的意见作为参考,但不能把这些的建议作为诊断。(abin译)
这个病例很复杂,有多种成分。愣了半天没想明白,提供一些初步考虑:
1、有明确的DCIS和LCIS
2、有可疑浸润,尤其低倍图所示(不存在小叶结构,脂肪组织中的肿瘤成分更像有浸润)
3、p63阳性罕见于极少数浸润癌(腺样囊性癌是例外,但HE图像不支持),不见于DCIS,因此考虑那些p63表达强度不均一的筛状结构是UDH,这些结构的HE图像也像UDH。
因此,现有的资料考虑:DCIS及LCIS,伴可疑浸润。
鉴别诊断:筛状结构、腺腔内嗜酸性分泌物、p63有表达……这些特点确实需要排除腺样囊性癌
