haemangioma n. a benign tumour of blood vessels. It often appears on the skin as a type of birthmark (see naevus). For example, a strawberry haemangioma is seen in newborn babies and infants, often on the face; it is red and may attain a very large size, but usually disappears spontaneously within the first year of life. Senile haemangiomas occur in the elderly. See also angioma.
