似乎是界限清楚的2cm肿块，我首选“1）包裹型乳头状癌？”，周围有导管内癌

It is true that the average size of  invasiv emicropapillary ca is large and tumor shows infiltrating growth. But special cases can be present.

DCIS is present in about 70% of invasive micropapillary ca

2）实体性乳头状癌？

Cannor buy them

If all areas like above, i would ca invasive micropapillary ca.

 这种形态还真没见过，

 您的诊断：

1）包裹型乳头状癌？

2）实体性乳头状癌？

3）浸润性导管癌？

4）浸润性微乳头状癌？

5）导管内乳头状癌？

6）其他？
