What is the term for a mass of blood trapped in tissue due to internal bleeding?

A hematoma refers to a localized collection of blood that has leaked from blood vessels into the surrounding tissues, typically due to trauma or injury that leads to internal bleeding. This accumulation of blood becomes encapsulated, forming a distinct mass that can vary in size and may appear as a bruise on the skin’s surface.

Understanding hematomas is crucial for bodywork professionals, as they can influence tissue recovery and the appropriate treatment methods. Unlike hemorrhage, which refers generally to bleeding, a hematoma is a specific manifestation of blood pooling. This distinction is important for recognizing and addressing client conditions effectively.

The other terms relate to different processes involving blood circulation; thrombosis refers to the formation of a blood clot within a blood vessel, while embolism describes a blockage caused by a clot or foreign material that travels through circulation. Hemorrhage is the broader term for bleeding itself, encompassing any loss of blood from the vascular system.
