Explanation:
A contusion is a closed soft-tissue injury from blunt trauma where small blood vessels are damaged under the skin without breaking the surface. The resulting leakage of blood into the tissues causes swelling and ecchymosis (the bruised, discolored skin). Abrasions and lacerations involve skin being broken, so they are open wounds, not closed injuries. A hematoma is a localized blood collection that can cause swelling as well, but the hallmark bruise (ecchymosis) with widespread swelling after blunt impact most specifically describes a contusion.
