Definition

An extremely common benign tumor, occurring most commonly in infancy and childhood, made up of newly formed blood vessels, and resulting from malformation of angioblastic tissue of fetal life; It can occur anywhere in the body but is most frequently noticed in the skin and subcutaneous tissues; About 75% are present at birth, and about 60% occur in the head and neck area; The majority in infancy will regress spontaneously; Some hemangiomas grow rapidly during the early months of life and may be a source of some concern, although virtually all disappear by about 5 years of age; They do not metastasize and simple excision will often be curative-------- (Dorland, 27th ed; from Stedman, 25th ed; DeVita Jr et al, Cancer: Principles & Practice of Oncology, 3d ed, p1355)---------------------
