haematoma

An accumulation of free blood anywhere in the body, that has partially clotted to form a semi-solid mass. Haematomas may be caused by injury or may occur spontaneously as a result of a bleeding or clotting disorder. In some sites, as within the skull, enlarging haematomas may be very dangerous. Infected haematomas may form abscesses.

Patient discussion about haematoma

Q. What is hematoma?

A. "hem" means blood, it's a very common bruise - when you fall off your bicycles, you get hit. if you don't cut yourself too in the process- blood vessels usually get ripped and blood flows to that area. this causes a red/blue color. after a couple of weeks it'll change color to green and then yellow. this is the blood cells disintegrate.
