Mammary gland: the neoplasm is composed of thick trabeculae and solid areas with various degrees of central necrosis. These epithelial structures are separated by a small amount of fibrovascular stroma. Neoplastic cells are medium-size, with indistinct cell borders and a moderate amount of amphophilic to acidophilic cytoplasm. The nucleus is central, round, medium-size, slightly hypochromatic, with a clumped chromatin and 1-5 medium size basophilic nucleoli. Anisokaryosis and anisocytosis are mild. Mitoses are numerous. |
