Which of the following terms describes a mass of blood that has leaked into surrounding tissue?

A hematoma is specifically defined as a localized collection of blood outside of blood vessels, typically resulting from injuries that cause blood to leak into surrounding tissues. This accumulation can occur in various parts of the body and is commonly associated with trauma, where capillaries or small blood vessels rupture, allowing blood to flow into nearby tissues, creating a visible swelling or bruise.

In contrast, edema refers to an excessive accumulation of fluid in the interstitial spaces of the body, which can occur for a variety of reasons including inflammation or heart failure, but is not specifically related to blood.

A contusion, often referred to as a bruise, represents a more general term for damage to the skin or tissues without breaking the skin surface, typically resulting from a direct blow or impact. While contusions may involve blood leakage, they are not synonymous with the term that specifically refers to a mass of blood.

Hemorrhage refers to the loss of blood from the vascular system, which can occur internally or externally. While it encompasses instances where blood has spilled into tissues, it does not specifically indicate the localized collection characteristic of a hematoma.

Understanding these distinctions helps clarify why a hematoma is the correct term for describing the mass of blood that has leaked into surrounding
