Mammary gland: the architecture of the mammary gland is preserved. The lumen of the ducts and alveoli of a few acini is moderately distended by closely-packed neoplastic cells. These cells are medium-size, polygonal, with indistinct cell borders and a small amount of amphophilic cytoplasm. The nucleus is central, oval, medium-size, oval, normochromatic, with a finely stippled chromatin and 1-2 inconspicuous basophilic nucleoli. Anisokaryosis and anisocytosis are mild. A few mitoses are present. A few neoplastic cells undergo single cell necrosis. There is mild fibrosis and pleocllular inflammation at the periphery of the affected ducts and acini. |
