Positive immunostaining for ER (400×) (A) and for Ki-67 (400×) (B) in nuclei of epithelial cells of HUT, note in both the marked staining of the most of the cells at the periphery of the spaces. Positive immunostaining for p63 in nuclei of myoepithelial cells of HUT occurred as a continuous layer (C) (200×); and occurred as a discontinuous layer pattern (200×)(D)in nuclei of myoepithelial cells of HUT. Positive immunostaining for p21in cytoplasm of epithelial cells of HUT (400×) (E) and in invasive mammary carcinoma (400×) (F).
