Mammary adenocarcinoma: this photomicrograph focuses on the papillary portions of the neoplasm. Neoplastic papillae have a slender fibrovascular core and are lined by a 2-15 cells-thick epithelium. Neoplastic cells are columnar to polygonal, with ill-defined cell borders and a small amount of amphophilic cytoplasm. The nucleus is oval to round, oriented in the long axis of the cell for columnar neoplastic cells, and slightly hyperchromatic. Numerous neoplastic cells undergo single cell necrosis and mitotic figures are numerous. |
