Infiltrating Duct Carcinoma (High Power)
Infiltrating Duct Carcinoma (High Power)

The blue arrows surround a nest of neoplastic cells in an infiltrating ductal carcinoma.
Although no central lumens are identifiable in this picture the cells are not infiltrating as single cells "indian filing".
The green arrowheads point to intervening stroma.
Mitotic figures are seen.
