Features: | |||
*Tumour within a vascular space. | |||
**Vascular space: endothelial cells, red blood cells. | |||
Note: | |||
*One strict definitions requires thrombus adherent to tumour.<ref name=pmid21804527/> | |||
DDx: | |||
*[[Lymphovascular invasion]] - no [[red blood cells]]. | |||
*Carryover of tumour - not attached to wall, no thrombus. | |||
