PATHOLOGY

Detailed explanation-1: -(HEE-muh-TOH-muh) A pool of mostly clotted blood that forms in an organ, tissue, or body space. A hematoma is usually caused by a broken blood vessel that was damaged by surgery or an injury. It can occur anywhere in the body, including the brain.

Detailed explanation-2: -It happens when an injury causes blood to collect and pool under the skin. The pooling blood gives the skin a spongy, rubbery, lumpy feel. A hematoma usually is not a cause for concern. It is not the same thing as a blood clot in a vein, and it does not cause blood clots.

Detailed explanation-3: -Soft-tissue hematomas are a common clinical entity often associated with trauma, surgery, and bleeding disorders. In the majority of cases, soft-tissue hematomas acutely appear and spontaneously resolve, but sometimes, they present as swellings that slowly expand and progressively increase with time.

Detailed explanation-4: -Accidents or bumps. Microscopic tears in the blood vessels under the skin in athletic people. Bleeding disorders-unexplained bleeding that occurs without reason. Thinner skin due to aging.
