Secretory mammary adenocarcinoma with squamous differentiation: this photomicrograph illustrates an area of cornification. Neoplastic cells are arranged in nests, trabeculae and glands. Neoplastic nests often rupture and are associated with a moderate interstitial lymphocytic, plasmacytic and histiocytic infiltration and, occasionally, mineralization (arrowhead). |
