Visible bluish or purplish mark beneath the surface of unbroken skin, indicating burst blood vessels in deeper tissue layers. Bruises are usually caused by a blow or pressure, but they may occur spontaneously in elderly persons. The yellowish hue that becomes visible as a bruise heals comes from the disintegration and gradual absorption of blood.
