**Monoclonal antibody to podoplanin.
**Useful to assess lymphovascular invasion.
 
*ADH and DCIS:<ref name=Ref_Lester122>{{Ref Lester|122}}</ref>
**E-cadherin.
***Present in most epithelial cells.
***Lost in LCIS & invasive lobular carcinoma.
**SMMHC (smooth muscle cell myosin heavy chain).
***Marks myoepithelial cells.
