#*LVI is usually very close -- typically within 0.1 cm.

#Contour of cells should differ from possible vessel wall.

#*DCIS with retraction artifact mimicing LVI has a contour that matches its surrounding fibrous tissue.

#Endothelium (usu. flat) should be visible.

#Lymphatics are found adjacent to [[blood vessels]] - vessels should be present in the near vicinity.
