What term describes the escape of blood from ruptured vessels?

The term that describes the escape of blood from ruptured vessels is ecchymosis. This condition occurs when blood accumulates outside of blood vessels due to injury or trauma, leading to a bruise-like discoloration on the skin. This term specifically refers to the extravasation of blood into the surrounding tissues, creating a visible mark that often changes color over time as the body reabsorbs the blood.

The other terms listed do not pertain to the escape of blood from vessels. For instance, endometriosis is a condition where tissue similar to the lining inside the uterus grows outside of it, and it is associated with pain and reproductive issues. Endarterectomy is a surgical procedure performed to remove plaque from arteries, primarily to improve blood flow and prevent strokes or heart attacks. Enucleation refers to the surgical removal of an organ or mass, often applied to the removal of an eye. Each of these terms has a distinct meaning and context that does not relate to the concept of blood escaping from ruptured vessels.
