A hematoma or haematoma is a localized collection of blood outside the blood vessels, usually in liquid form within the tissue. An ecchymosis, commonly (although erroneously) called a bruise, is a hematoma of the skin larger than 10mm. It is not to be confused with hemangioma, which is an abnormal buildup of blood vessels in the skin or internal organs.
