While we try to be careful, many of us have suffered a bruise every now and again. Bruises can result from many sources, such as accidental contact with table legs or awkward meetings of thumbs and hammers. But, medically speaking, what exactly is a bruise, and what medical terms do the professionals use to talk about bruises?  

What is the medical term for bruise

A bruise is a discoloration that results from bleeding without breaking the skin. Most often, bruises are caused by trauma or injuries that damage capillaries under the skin without rupturing the skin itself. As a result, the blood pools underneath the surface of the skin, which causes a visible change in color.

In medicine, the word contusion is most often used as the technical term for a bruise. Specifically, contusion is used to refer to bruising caused by physical injuries or physical trauma to the body. The noun contusion comes from the verb contuse, which comes from the Latin verb contundere meaning “to bruise” or “to crush.”    

The word ecchymosis is also used as a technical term for bruising. This term is often used to refer to bruising that is caused by medical conditions or illnesses rather than physical injuries. For example, discoloration caused by cancer or blood clots may be referred to as ecchymosis. Ecchymosis comes from the Greek ekchýmōsis, which means extravasation

Bruises often result from physical injuries, such as being hit or accidentally bumping a body part, and they typically heal by themselves over time. Bruising that isn’t caused by physical trauma, most often called ecchymosis, may be a sign of a medical disorder.   

Healthcare professionals use medical terms—such as contusion and ecchymosis—to provide universal medical care and standardize communication within the medical field.
