Figure 5 :(A) Secti ons show numerous closely packed arborescent structures composed of fi bro vascular stalks covered by a layer of myoepithelial cells and epithelial cells. (H and E x100), (B)Lining epithelium of papillomatous proliferati on shows myoepithelial cells and epithelial cells. (H and E, x400, (C) Apocrine metaplasia, infl ammati on and ductal pseudo infi ltrati ve patt ern at places. (H and E, x100), (D) Focal atypical epithelial changes were also seen. (H and E, x 400), (E): IHC for smooth muscle acti n highlighti ng myoepithelial cells.
