Mammary gland: the neoplasm is composed of ectatic glands which are partially filled with slender papillary projections. These epithelial structures are lined by a one cell-thick cuboidal epithelium supported by a small amount of dense fibrovascular stroma. The lumen of some glands contains clumps of degenerated neoplastic cells. Neoplastic cells are cuboidal and have a moderate amount of acidophilic cytoplasm. The nucleus is medium-sized, central and oval. Fixation artifacts prevent further interpretation of these tissues. |
