The raised area of a bump or bruise results from blood leaking from injured blood vessels into the tissues, such as muscle, as well as from the body's response to the injury. A purplish, flat bruise that occurs when blood leaks out into the top layers of skin is called an ecchymosis.iny blood vessels near the surface of the skin can burst from a bump, a scrape, or injection-any kind of physical distress. Bruises change color like a mood ring as they mature (from black and blue to green to yellow) and last about one week on the face and two weeks on the body.
Hemangioma/hematoma: It depends on how long you had the bruise for: if few weeks or few months it may be a hematoma (blood that leaked from ruptured vessels due to trauma or bruising) and should clear shortly but if you had for years or since birth it can be a vascular anomaly or hemangioma (benign tumor of blood vessels).
