Figure 4. Photomicrograph of the resected superior mesenteric vein with a tumor thrombus. The metastatic colonic adenocarcinoma fills the lumen of the vein (asterisk marks vein wall), and it is composed of anastomosing neoplastic tubules with dirty necrosis (arrow). Scattered thin-walled vessels (letter v) are present, consistent with recanalization. Hematoxylin and eosin stain, 20× magnification, scale bar indicates 500 μm.
