Saw you above response. Can you make the final dx based on morphology and IHC results I showed you?
I hope every one can write down your dx and reasons. I am interested in knowing your thinking. Then I know what I should discuss. Internet is good. You can write what you want to and you do not have any responsibility. I do not know any one of you. It is a free stage for every one.
Anyway I will discuss this topic in details later.
8226; 膨胀性生长方式,推挤性边缘
8226; 周边多量淋巴细胞浸润
8226; 肿瘤中央出现无结构的纤维瘢痕,往往还伴有地图样坏死
8226; 肿瘤细胞多呈合体状,界限不清,胞质不丰富
8226; 核分裂象多见,常>20个/10HPF
8226; 肿瘤组织常出现梭形细胞、透明细胞、基底细胞样或鳞状细胞化生
IHC表型
ER、PR和HER2(-)
CK5/6、CK14(+)
EGFR常(+)
但不知道只有免疫表型而无形态学特征者是否可以诊断
期待赵老师讲解
