Lung: a pulmonary metastasis of a mammary neoplasm is present at the center of the photomicrograph. It is composed of small coalescing nests separated by a scant amount of fibrovascular stroma. Neoplastic cells are cuboidal, polygonal or oat-shaped, with ill-defined cell borders and a small amount of amphophilic cytoplasm. The nucleus is central, oval, normochromatic, with a finely stippled chromatin and 1-5 small basophilic nucleoli. Anisokaryosis and anisocytosis are mild. Mitoses are numerous. |
