Hemangioblastoma - 새창 A benign tumor of the nervous system that may occur sporadically or in association with HIPPEL-LINDAU DISEASE. It accounts for approximately 2% of intracranial tumors, arising most frequently in the cerebellar hemispheres and vermis. Histologically, the tumors are composed of multiple capillary and sinusoidal channels lined with endothelial cells and clusters of lipid-laden pseudoxanthoma cells. Usually solitary, these tumors can be multiple and may also occur in the brain stem, spinal cord, retina, and supratentorial compartment. Cerebellar hemangioblastomas usually present in the third decade with INTRACRANIAL HYPERTENSION, and ataxia. (From DeVita et al., Cancer: Principles and Practice of Oncology, 5th ed, pp2071-2)
Synonyms : Multiple Hemangioblastomas, Hemangioblastoma, Multiple, Hemangioblastomas, Hemangioblastomas, Multiple, Multiple Hemangioblastoma
Hemangioendothelioma - 새창 A neoplasm derived from blood vessels, characterized by numerous prominent endothelial cells that occur singly, in aggregates, and as the lining of congeries of vascular tubes or channels. Hemangioendotheliomas are relatively rare and are of intermediate malignancy (between benign hemangiomas and conventional angiosarcomas). They affect men and women about equally and rarely develop in childhood. (From Stedman, 25th ed; Holland et al., Cancer Medicine, 3d ed, p1866)
Synonyms : Hemangioendotheliomas
Hemangioendothelioma, Epithelioid - 새창 A tumor of medium-to-large veins, composed of plump-to-spindled endothelial cells that bulge into vascular spaces in a tombstone-like fashion. These tumors are thought to have "borderline" aggression, where one-third develop local recurrences, but only rarely metastasize. It is unclear whether the epithelioid hemangioendothelioma is truly neoplastic or an exuberant tissue reaction, nor is it clear if this is equivalent to Kimura's disease (see ANGIOLYMPHOID HYPERPLASIA WITH EOSINOPHILIA). (Segen, Dictionary of Modern Medicine, 1992)
Synonyms : Epithelioid Hemangioendothelioma, Epithelioid Hemangioendotheliomas, Hemangioendotheliomas, Epithelioid
Hemangioma - 새창 A benign tumor, made up of an overgrowth of BLOOD VESSELS. It is extremely common, occurring mostly in infancy and childhood. It can occur anywhere in the body but is most frequently noticed in the SKIN and SUBCUTANEOUS TISSUE. About 75% are present at birth, and about 60% occur in the head and neck area. (from Stedman, 25th ed; DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1355)
Synonyms : Chorangioma, Angiomas, Chorangiomas, Hemangiomas, Hemangiomas, Histiocytoid, Hemangiomas, Intramuscular, Histiocytoid Hemangioma, Histiocytoid Hemangiomas, Intramuscular Hemangioma, Intramuscular Hemangiomas
Hemangioma, Capillary - 새창 A dull red, firm, dome-shaped hemangioma, sharply demarcated from surrounding skin, usually located on the head and neck, which grows rapidly and generally undergoes regression and involution without scarring. It is caused by proliferation of immature capillary vessels in active stroma, and is usually present at birth or occurs within the first two or three months of life. (Dorland, 27th ed)
Synonyms : Capillary Hemangioma, Capillary Hemangiomas, Hemangiomas, Capillary
