N: 1. 1867 medical Latin, from angio- + -oma. angio-: before verbs angi-, word-forming element now usually meaning “covered or enclosed by a seed or blood vessel,” from Latinized form of Greek angeion “a vessel, receptacle,” diminutive of angos “chest, box,” of unknown origin. -oma: word-forming element, from Greek -oma, with lengthened stem vowel + -ma, suffix forming neuter nouns and nouns that indicate result of verbal action (equivalent of Latin -men); especially taken in medical use as “morbid growth, tumor,” based on sarcoma, carcinoma.
2. In Dorland´s Illustrated Medical Dictionary, the term angioma appears as a synonym of hemangioma.
3. A common type of vascular malformation, usually seen in infancy and childhood, consisting of newly formed blood vessels that result from malformation of angioblastic tissue of fetal life. There are two main types: capillary hemangiomas and cavernous hemangiomas.
4. A general term denoting a benign or malignant vascular malformation that resembles the classic type of hemangioma but occurs at any age.
5. Types of angioma (or hemangioma):

• Capillary hemangioma: 1.the most common type of hemangioma; most are composed of closely packed aggregations of capillaries that are separated by scant connective stroma and conform to the caliber of normal capillaries. According to one classification, strawberry h., nevus flammeus, cherry angioma, and pyogenic granuloma are all types of capillary hemangiomas. 2. Strawberry hemangioma.
• Cavernous hemangioma: a vascular tumor composed mainly of large dilated blood vessels that often contain large amounts of blood; the usual location is in the skin, subcutaneous tissue, or both, although it may also be found in viscera such as the liver, spleen, pancreas or brain. Most present in early life but usually not at birth. The typical superficial lesions are bright to dark red in color; deep lesions have a blue color. Called also cavernoma, cavernous angioma, and strawberry mark or nevus.
