Mammary gland: the cyst is mostly lined by a several (2-4) cells-thick epithelium (earlier stages of macrocysts are lined by a one cell-thick epithelium). In some areas, the epithelium has retained the one cell-thick appearance, which is typical of early stages of macrocysts. The neoplastic epithelium forms glands which are variably ectatic. The cells are cuboidal, with indistinct cell borders, and a moderate amount of acidophilic cytoplasm. Their nucleus is basal, oval, and medium-sized. There is no evidence of atypia and the mitotic rate is low. |
