Mammary gland: the neoplasm is composed of closely-packed branching glands with an inconspicuous lumen. These glands are lined by a one cell-thick epithelium and are supported by a small amount of fibrovascular stroma. Neoplastic cells are low columnar, with indistinct cell borders and a moderate amount of acidophilic cytoplasm. The nucleus is basal, often oriented in the long axis of the cell, medium-sized,normochromatic, with a finely stippled chromatin and 1-2 small basophilic nucleoli. Anisokaryosis and anisocytosis are mild. A few mitoses are present. |
