(A) LVI-positive by D2-40 staining. Positive staining of lymphatic endothelium with D2-40 shows the presence of tumor emboli in the lumen of the lymph vessels (red arrow). The endothelia of the adjacent blood vessels are negative for D2-40 (black arrow) (×100). (B) LVI-negative by D2-40 staining. No tumor emboli are noted within the lumen of the lymph vessels positive stained by D2-40 (red arrow). The endothelia of the adjacent blood vessels are negative for D2-40 (black arrow) (×100). LVI = lymphatic vessel invasion.
