i feel it has both LCIS (first several photos) and DCIS (last photo), low nuclear grade. Invasive cancer cannot be excluded because the first several photos show small clusters of neoplastic cells in desmoplastic-like stroma. E-cadherin and p63 will certainly help.
Happy new year, Dr.cqzhao!
These pictures show LCIS or DCIS, which can be differentiated by each other for immunostaining of p120 and E-cadherin. In the stromal pseudoinvasion is presented, and p63 immunostaining may confirm it.
