The following article is from The Great Soviet Encyclopedia (1979). It might be outdated or ideologically biased.



or bruise, a hemorrhage into the soft tissues as a result of a blow or pressure from a blunt object; blood may also escape under nonmechanical influences (sepsis, asphyxia, and overchilling, for example). The blood flowing out of the injured blood vessels into the tissue changes color (from dark red to yellowish green) with decomposition and biochemical conversion. The type of object that applied the blow and the age of the trauma may be judged by the shape and color of the surface bruise (“black-and-blue mark”). Extensive ecchymoses are called hematomas.
