A vascular tumor is a tumor of vascular origin; a soft tissue growth that can be either benign or malignant, formed from blood vessels or lymph vessels. [1] Examples of vascular tumors include hemangiomas, lymphangiomas, hemangioendotheliomas, Kaposi's sarcomas, angiosarcomas, and hemangioblastomas. An angioma refers to any type of benign ...
Angiosarcoma is a rare and aggressive cancer that starts in the endothelial cells that line the walls of blood vessels or lymphatic vessels.Since they are made from vascular lining, they can appear anywhere and at any age, but older people are more commonly affected, and the skin is the most affected area, with approximately 60% of cases being cutaneous (skin).
Tumors of the hematopoietic and lymphoid tissues (American English) or tumours of the haematopoietic and lymphoid tissues (British English) are tumors that affect the blood, bone marrow, lymph, and lymphatic system. [1][2] Because these tissues are all intimately connected through both the circulatory system and the immune system, a disease ...
Some cancer cells known as circulating tumor cells acquire the ability to penetrate the walls of lymphatic or blood vessels, after which they are able to circulate through the bloodstream to other sites and tissues in the body. [6] This process is known (respectively) as lymphatic or hematogenous spread. After the tumor cells come to rest at ...
Blood vessels are the structures of the circulatory system that transport blood throughout the human body. [1] These vessels transport blood cells, nutrients, and oxygen to the tissues of the body. They also take waste and carbon dioxide away from the tissues. Blood vessels are needed to sustain life, because all of the body's tissues rely on ...
Kaposi's sarcoma (KS) is a type of cancer that can form masses on the skin, in lymph nodes, in the mouth, or in other organs. [4][6] The skin lesions are usually painless, purple and may be flat or raised. [6][8] Lesions can occur singly, multiply in a limited area, or may be widespread. [6] Depending on the sub-type of disease and level of ...
Kaposi sarcoma is a malignant vascular tumor that is linked with an infection of the human herpesvirus 8 (otherwise known as HHV-8). It is a cancer of the blood vessel endothelial cells. This virus is thought to get inside of the cells, and cause the cells to replicate uncontrollably. This type of cancer is seen in people who have suppressed ...
An MRI can detect cancer or thrombosis (blood clots). ... If treatment is required, selective arterial embolization (blocking a blood vessel) is one option. Also called ligation, ...
