Both cavernous capillary hemangiomas and cavernous venous malformations produce localized destruction, destroying the surrounding normal tissue and becoming either their own tumor tissue or their own venous malformation tissue. Local invasive destruction does not produce cancer or form malignant tumors, and is a benign hemangioma and a benign vascular malformation. Therefore, spongy capillary hemangioma, regardless of the degree of local destruction, develops only locally, and spongy venous vascular malformation is also a benign lesion with local destructive power. However, local invasion and destruction can also have more serious consequences, although not like malignant tumors or cancer that produce systemic metastasis, but local invasion can destroy many tissues, such as skin, fat, fascia, blood vessels, nerves and even bones, such as spongy venous vascular malformation, which can appear as a kind of pathological fracture or even bleeding.
