Mammary gland: this is a nodular, well-delineated, unencapsulated, invasive, densely cellular neoplasm. The neoplasm is composed of interconnected ducts separated by a moderate amount of dense fibrovascular stroma. There are numerous areas of cornification which appear as concentric whirls of a strongly acidophilic material. There is a mild to moderate lymphocytic and plasmacytic infiltrate at the periphery of the tumor. Cytological details are poor because the tissue was fixed in ethanol. |
