English: Histopathology of adenocarcinoma, H&E stain, with typical features. This case is an invasive carcinoma of no special type of the breast. In this case, invasion is supported by presence within fatty tissue (which, however, may also occur in benign conditions such as microglandular adenosis). The large size of the nuclei can be appreciated by comparing to the benign dark stromal cell by the left image border. In reality, the visual features vary substantially, both by subtypes of adenocarcinoma as well as between individual cases.
