H & E staining and immunohistochemical staining using CD10 and p63. (a) H & E staining revealed papillary proliferation of epithelial cells. (b) Proliferation of glands showed a pseudoinvasive pattern. Immunohistochemical staining using (c) CD10 and (d) p63 was performed to confirm the presence of myoepithelial cells in neoplastic ducts. H & E, hematoxylin and eosin.
