Bruise

Bruise

A bruise, also called a contusion, is a type of relatively minor hematoma of tissue in which capillaries and sometimes venules are damaged by trauma, allowing blood to seep into the surrounding interstitial tissues. Bruises can involve capillaries at the level of skin, subcutaneous tissue, muscle, or bone. A bruise may be named by the length of its diameter as an petechia (less than 3 mm), purpura (3 mm to 1 cm) or ecchymosis (1 to 3 cm), although these terms can also refer to internal bleeding not caused by trauma.

Famous quotes containing the word bruise:

    Ah, little road, brown as my race is brown,
    Your trodden beauty like our trodden pride,
    Dust of the dust, they must not bruise you down.
    Rise to one brimming golden, spilling cry!
    Helene Johnson (b. 1907)

    Now it is autumn and the falling fruit
    and the long journey towards oblivion.
    The apples falling like great drops of dew
    to bruise themselves an exit from themselves.
    —D.H. (David Herbert)
