#Must be outside of the tumour proper. | |||
#*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. | |||
