Solid and comedo mammary carcinoma: neoplastic cells are closely packed, medium-size, polygonal, with indistinct cell borders and a small to moderate amount of amphophilic cytoplasm. The nucleus is central, oval, medium-size, with a slightly contoured nuclear membrane, normochromatic, a clumped chromatin and 1-3 small nucleoli. Anisokaryosis and anisocytosis are mild. Mitotic rate is elevated. Neoplastic cells in some places seem to be located in the stroma of the neoplasm and are not separated from the stroma by a discrete basement membrane. |
