Tumors of blood vessels
Blood vessel derived tumors may arise from:
- endothelial cells
- cells supporting or surrounding blood vessels
Most arise in the soft tissues or viscera. Primary tumors of the large vessels (eg. aorta, IVC) are rare and are usually connective tissue sarcomas.
Vascular tumors may be benign or malignant. Benign tumors form recognisable vascular channels filled with blood or lymphatic fluid. Malignant tumors are usually more solid and cellular without well-formed vascular channels.
