A vascular reaction involving the deep dermis or subcutaneous or submucosal tissues, representing localized edema caused by dilatation and increased permeability of capillaries, and characterized by development of giant wheals.
1. Extensive increase in vascularity of the subcutaneous tissue, producing great thickening simulating large, diffuse angioma formation.
2. Extensive angiomatosis (a tumor composed chiefly of lymph and blood vessels) of the subcutaneous tissues.
Now known as hemangioendothelioma or a true neoplasm of vascular origin, characterized by proliferation of endothelial cells in and about the vascular lumen; it is usually considered to be intermediate in grade between hemangioma and hemangiosarcoma.
The presence of malignant tumors of vascular origin occurring most frequently on the face and scalp of elderly men.
An angioma with firbroblastic tissue between the vascular structures.
A neoplasm composed of fibrocytes, capillaries, and adipose tissue. Also called angiolipofibroma.
A lesion characterized by fibrous tissue and vascular proliferation; it often occurs as one or more small, flesh-colored papules, particularly on the face.
Fibrosis (tissue or fibers laid down at a wound site) of the walls of blood vessels.
Referring to a lymphoid follicle and its blood vessels.
1. The development of new blood-vessels.
2. Development of blood vessels in the embryo.
1. Pertaining to angiogenesis; also called angiopoietic and vasculogenic.
2. Arising in the circulatory system.
A protein that stimulates the formation of new blood vessels.
A single-chain basic protein cloned from molecules of the tumor angiogenesis factor (TAF) in human colon cancer cells, angiogenin is used experimentally to stimulate the development of new blood vessels in wound healing, in a cerebrovascular accident, and in coronary artery disease.
A tumor that is a mixed glioma and angioma rich in blood vessels.
Occurrence of multiple areas of proliferating capillaries and neuroglia or a condition of multiple angiogliomas.
Glial scarring about a blood vessel or a condition of multiple angiogliomas.
