hematoma

a localized collection of extravasated blood, usually clotted, in an organ, space or tissue. Contusions (bruises) are familiar forms of hematoma that are seldom serious. Hematomas can occur almost anywhere on the body; they are almost always present with a fracture and are especially serious when they occur inside the skull, where they may produce local pressure on the brain. In minor injuries the blood is absorbed unless infection develops.

For regional hematomas of individual importance see under anatomical name, e.g. ear, penile, vaginal, brain, ethmoid.
