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]
Occasionally seen in the benign tumours:
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.
