Intraductal Carcinoma (High Power)

This is a close-up of a large duct completely filled with neoplastic cells.
The cells are relatively monotonous with round to oval nuclei.
The neoplastic cells are contained within an intact basement membrane.
The neoplastic cells show no orientation to a lumen (loss of polarity).
