Angioinvasion, also vascular invasion, is spread of tumour into a blood vessel.[1]
Angioinvasion is typically lumped with lymphatic invasion and referred to as lymphovascular invasion. This article only deals with angioinvasion.
General
The distinction between lymphatic invasion and lymphovascular invasion is usually not important. One important exception is the thyroid gland.[2]
Microscopic
Features:
- Tumour within a vascular space.
- Vascular space: endothelial cells, red blood cells.
Note:
- One strict definitions requires thrombus adherent to tumour.[2]
DDx:
- Lymphovascular invasion - no red blood cells.
- Carryover of tumour - not attached to wall, no thrombus.
