Infiltrating Duct Carcinoma (Low Power)
Infiltrating Duct Carcinoma (Low Power)

This a low power view showing predominantly invasive or infiltrating carcinoma (blue arrows). The photograph is too low power to see what type of invasive disease it is.
There is also intraductal carcinoma (white arrows); it is the large size of the ducts completely filled with cells that supports the diagnosis of intraductal carcinoma at this power.
In light of the presence of intraductal carcinoma it is most likely that the invasive disease is invasive ductal carcinoma.
