A vascular tumor is a vascular anomaly where a tumor forms from cells that make blood or lymph vessels; a soft tissue growth that can be either benign or malignant.[1] Examples of vascular tumors include hemangiomas, hemangioendotheliomas, Kaposi's sarcomas, angiosarcomas, and hemangioblastomas. An angioma refers to any type of benign vascular tumor.[2]
Some vascular tumors can be associated with serious blood-clotting disorders, making correct diagnosis critical.[3]
A vascular tumor may be described in terms of being highly vascularized, or poorly vascularized, referring to the degree of blood supply to the tumor.
