Figure 7From: Confocal Microscopy of Unfixed Breast Needle Core Biopsies: A Comparison to Fixed and Stained Sections Poorly differentiated infiltrating ductal carcinoma, nuclear grade 3. Although the margins of the nuclei are not sharply defined in CSLM (A), the arrangement of tumor cells in diffusely infiltrating nests and aggregates (*) is evident. Residual fat cells are seen as dark, round spaces (arrows). The H&E image (B) shows sharper definition of the nuclear features in this case.Back to article page
