In cases of high numbers of vessels, erosions and crusts can follow treatment sessions for several days.
Therefore, our data demonstrate that the subcutaneous injection of vole TS-like cells causes cellular invasion into the host blood vessels and erosion of blood vessel walls, resulting in the development of large haemorrhagic tumours.
Given their hypervascular nature, expansive growth, change in the structure of the vessel walls, erosion and necrosis, these lesions can bleed.
The internal jugular catheters may migrate up to 3 cm with neck flexion [ 2] which can result in the catheter migrating to a more acute angle abutting the vessel wall causing erosion.
Rather, weakening of the wall of major vessels by tumour erosion, necrosis, cavitation, or other concurrent pathological conditions are likely to play a central role.
This peculiarity could be helpful in the differential diagnosis with ductal adenocarcinoma, which causes vascular infiltration at early stages, with erosion of vessel walls, stenoses and eventually tumoral thrombosis [14].
A 31-year-old woman (a and b) with Ewing sarcoma, a large mass with irregular shape, lobulated margins, heterogeneous enhancement, intratumoural vessels but no rib erosion.
There were instances of its hard edges causing erosion of vessels.
Pathological changes due to cancer, e.g. tumour erosion of vessels, may also be important [ 28].
To ensure that we are outside of the vessels location, some erosions are applied.
