(hē-man'jē-ō-en'dō-thē'lē-ō'mă),
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; in the elderly, may be malignant (angiosarcoma or hemangiosarcoma), but in children are benign and probably represent a growing stage of capillary hemangioma. Locally invasive but only rarely metastasize.
