Which term describes a swelling formed from blood and lymph flow into tissue, with clotting encapsulated by connective tissue?

• A. Hematoma
• B. Contusion
• C. Myofascial Trigger Points
• D. Tendinosis

Answer: (A)

A hematoma is a localized swelling that occurs when blood leaks from damaged vessels into the surrounding tissue. The blood pools and clots there, and over time the body forms a connective-tissue capsule around this clot, creating the encapsulated space you feel as a lump. This encapsulated blood collection distinguishes a hematoma from a simple bruise (contusion) and from conditions like myofascial trigger points or tendinosis, which involve tissue changes or pain mechanisms rather than bleeding into tissue.
