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 that form solid areas with a few linear clefts. These cells are medium-size, polygonal, with indistinct cell borders and a small amount of amphophilic cytoplasm. The nucleus is central, oval to slightly elongated, medium-size, oval to elongated, normochromatic, with a coarsely clumped chromatin and 1-2 inconspicuous basophilic nucleoli. Anisokaryosis and anisocytosis are mild. A few mitoses are present. There is mild fibrosis and pleocllular inflammation at the periphery of the affected ducts and acini. |
