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.

Thank you for sharing above photos. Clearly it is IDC and DCIS now. The surgeon did not give you the invasive area for frozen. It is good evidence that open surgery with frozen is not a good method for breast lesions. This method has not been used for about 30 year in the usa. Do not understand our surgeons still love this method in China
