A non-bleeding injury to the skin.
The leakage of blood into the tissues, resulting in a black and blue appearance as a result of a blow.
A dark painful area on the skin, where blood has escaped under the skin following a blow.
Injury that does not cause the skin to break or bleed but usually results in discoloration because of clotted blood below the skin’s surface.
A collection of blood in unbroken tissue; also known as a contusion. Most bruises fade slowly within 10 to 14 days. As a bruise fades, the changing colors represent chemical changes in the hemoglobin of red blood cells as they are broken down and reabsorbed into the bloodstream. If bruises do not fade, if they appear for no reason, or if they are accompanied by persistent pain or headache, medical attention is needed.
An area of skin discoloration caused by the escape of blood from ruptured underlying vessels following injury. Initially red or pink, a bruise gradually becomes bluish, and then greenish yellow, as the hemoglobin in the tissues breaks down chemically and is absorbed. It may be necessary to draw off blood from very severe bruises through a needle, to aid healing.
Bruises, or contusions, result from injuries to the deeper layers of the skin or underlying tissues, with variable bleeding but without open wounds. Bruises range from a slight bluish discoloration, due to minimal trauma and haemorrhage, to a large black swelling in more severe cases. Diseases such as haemophilia and scurvy, which reduce coagulation, should be suspected when extensive bruises are produced by minor injuries. Bruises change colour from blue-black to brown to yellow, gradually fading as the blood pigment is broken down and absorbed. Bruising in the abdomen or in the back in the area of the kidneys should prompt the examining doctor to assess whether there has been any damage to internal tissues or organs. Bruising in children, especially repeated bruising, may be caused by physical abuse. Adults, too, may be subjected to regular physical abuse.
A traumatic injury (usually to the skin but sometimes to internal organs) in which blood vessels are broken but tissue surfaces remain intact. Discoloration, swelling, inflammation, and pain are typical signs and symptoms. Fresh bruises on the skin are often red or purple. Older bruises may turn green and then yellow or brown, as the blood products within them age and are reabsorbed, but gauging the age of a bruise by its color is imprecise, at best. Bruising in infants may suggest occult child abuse. Bruising in the elderly is more often an indication of the use of anticoagulant drugs than of physical mistreatment.
A bruise refers to a discolored region beneath the skin resulting from the leakage of blood from injured capillaries, which are minuscule blood vessels. Initially, the blood appears blue or black in color. Over time, as the red pigment in blood called haemoglobin breaks down, the bruise transitions to a yellowish hue.
If a bruise persists for more than a week without fading, appears without an identifiable cause, or is disproportionately severe following a minor injury, it could potentially indicate the presence of a bleeding disorder.
A superficial injury to the skin or soft tissues where tiny blood vessels are damaged, resulting in minor bleeding into the tissues and the characteristic blue discoloration. Over the next ten days, the blood is absorbed, and the skin changes color from blue to green to yellow before fading completely. The only effective initial treatment is applying an ice pack or cold compress; unconventional remedies like raw meat or tincture of arnica have no impact. Spontaneous bruising, which occurs without any history of injury, can be observed in individuals with specific blood disorders like leukemia.
