Mammary gland: the neoplasm is locally invasive. It is composed of glands and 3-6 cells-thick trabeculae supported by a moderate amount of fibrovascular stroma with a mild lymphocytic and plasmacytic inflammation. Neoplastic cells are polygonal to low columnar, with indistinct cell borders and a moderate amount of amphophilic cytoplasm. The nucleus is central, oval, medium-sized, hypochromatic and with 1-3 medium-size to large amphophilic nucleoli. Anisocytosis and anisokaryosis are mild to moderate. Mitoses are numerous. Numerous neoplastic cells undergo apoptosis. |
