A bruise, also called a contusion or ecchymosis, is an injury to biological tissue in which the capillaries are damaged, allowing blood to seep into the surrounding tissue. It is usually caused by blunt impact. Sometimes bruises can be serious, leading to other more life threatening forms of hematoma, or can be associated with serious injuries, including fractures and internal bleeding. Bruising depends on several things, such as how tough a person's skin tissue is, whether a person has certain diseases or conditions, or whether a person's taking certain medications.

Minor bruises may be easily recognized, in people with light skin color, by their characteristic blue or purple appearance in the days following the injury. Vigorous exercise may also cause bruises due to bringing about small tears in blood vessels walls. Bruises also develop easily in the elderly, because the skin and blood vessels have a tendency to become thinner and more fragile with aging, and there is an increased use of medications that interfere with the blood clotting system.
Bruising is usually a minor problem, which does not require a medical diagnosis. However, faced with extensive bruising, bruising with no apparent cause, or bruising in certain locations, a physician will pursue an evaluation that will include a number of blood tests. If the area of the bruise becomes hard, an x ray may be required.
