For this case I really though microinvasin was likely in the time when I read H&E.
Lession: Pathologists should always be cautious, should be too confident in your daily practice. If you are not 100% sure of your diagnosis, please do not sign out your cases with this diagnosis. This is the basic principle for pathologists.

虽然呈大小不等不规则的癌细胞巢,但似乎还有小叶结构样的分布,也没有纤维间质反应,我认为是导管癌累及小叶(或称小叶癌化)而不是浸润癌,伴有较多的淋巴细胞浸润。IHC如显示癌巢周围有肌上皮存在,则很有帮助。
(我个人认为所谓小叶癌化这种情况,其实很有可能是一种特殊形态的、早期的导管原位癌)
(小叶原位癌有时可以呈导管样的形态,导管癌为什么不可以呈小叶样的形态,既然它们都是起源于TDLU)
呵呵,妄加议论而已
