Pathology Image Detail

Caption	Mammary adenoma: this photomicrograph of the periphery of the neoplasm illustrates the radiating glandular pattern with gradual transition into cords and trabeculae. Neoplastic cells are medium-sized, polygonal to cuboidal, with indistinct cell borders and a moderate amount of homogeneously eosinophilic cytoplasm. The nucleus is basal, round, and normochromatic. Anisocytosis and anisokaryosis overal are mild, although a few cells have a very large nucleus (arrowhead). There is prominent hyperplasia and atypia in the nearby mammary parenchyma.
