Most likely invasive ca is not present. Of cause myoepithelial marker stains can be performed if you are suspicious of invasion.

If invasin can be ruled out, I think this case is a borderline case. I can buy it as DCIS or ADH.

Why can it be ADH:

Focal lesion in several ducts

Atypical proliferation is not involved entire ducts.

Low nuclear grade.

在我们基层冰冻报导管内，临床作简根治. It is not standard care. Surgeons should have responsibility.

To pathologists: You need to know what surgeons will do if you reported the results on your frozen.

If you are not sure the dx of frozen, you always can defer the diagnosis for perminant slides.

 在基层工作的病理科医生他们能坚持就是一种无私的奉献

这话说的情真意切

不过，该例大医院会诊不够导管内癌？那是怎么发的？

再者，就凭一家医院会诊就赔钱了？看来病理科要应付的除了日常工作、患者沟通等方面的事情外，还要注意，让医院听到病理科的声音……
