Mammary gland: the mammary gland is expanded by a large polycystic mass lined by a one to two cells-thick cuboidal to tall columnar epithelium. The cells lining the cysts have distinct cell borders and a moderate to large amount of acidophilic cytoplasm that often contain lipid vacuoles of various sizes. The nucleus is randomly located in the cell, is large, oval, hyperchromatic, and with a coarsely clumped chromatin. Anisokaryosis and anisocytosis are prominent. A few mitoses are detected. |
