Which term is defined as a bruise not caused by pressure?

• A. Contusion
• B. Edema
• C. Ecchymosis
• D. Anaphylaxis

Answer: (C)

Bruising terms describe how blood leaks under the skin after vessels are damaged. Ecchymosis refers to a patch of skin discoloration caused by blood escaping from small vessels into surrounding tissue; it’s typically larger than tiny pinpoint bleeding and doesn’t require a clear external pressure event to form. You may see ecchymosis after minor trauma, but it can also occur without a direct blow, due to spontaneous vessel rupture or clotting issues. Over time the color changes as the blood is reabsorbed. This differs from a contusion, which is a bruise specifically from blunt force or pressure causing tissue injury. Edema is swelling from fluid buildup, and anaphylaxis is a life-threatening allergic reaction. So the term for a bruise not caused by pressure is ecchymosis.
