Angiosarcoma is a malignant neoplasm (cancer) of endothelial-type cells that line vessel walls. This may be in reference to blood (hemangiosarcoma) or lymphatic vessels (lymphangiosarcoma).Its origin typically readily permits metastases to distant sites. Most tumors of visceral blood and lymphatic vessel walls are malignant. Hemangiosarcomas and lymphangiosarcomas of the skin are not common.[citation needed].
