Hematoma
A hematoma or haematoma is a localized collection of blood outside the blood vessels, usually in liquid form within the tissue. An ecchymosis, commonly (although erroneously) called a bruise, is a hematoma of the skin larger than 10mm.
It is not to be confused with hemangioma, which is an abnormal buildup of blood vessels in the skin or internal organs.
Presentation
The word "haematoma" came into usage around 1850. The word derives from the Greek roots "heme-" (blood) and -oma, from soma, meaning body = a body of blood. Another etymological derivation would be from "haemat-" and "-oma" = "-ing", thus simply "bleeding".
Hematomas can occur within a muscle. Some hematomas form into hard masses under the surface of the skin. This is caused by the limitation of the blood to a subcutaneous or intramuscular tissue space isolated by fascial planes. This is a key anatomical feature that prevents such injuries from causing massive blood loss. In most cases the sac of blood or hematoma eventually dissolves; however, in some cases they may continue to grow or show no change. If the sac of blood does not disappear, then it may need to be surgically removed. Hematomas can occur when heparin is given via an intramuscular route; to avoid this, heparin must be given intravenously or subcutaneously.

Home To Me
by: StereophonicsThat's my home to me
That's my home to me
Please don't take it from me
Please don't take it from me
From Me
Electric lights blow my stare
I'm crawling for a space to breath
Why should my home concern your needs
Please don't take it from me
A baby chair
A rocking horse
A nervous wreck
A memory loss
And sleeping pills
Ease the pain
I'm coming back
I'm back again again
That's my home
That's my life to me
Please don't take it away from me
