It may be produced by stoppage of the blond-supply, as in embolism, by mechanical violence, by chemical agency, or by excessive heat or cold. It may involve large masses of tissue, or small clusters of cells, or scattered individual cells. The necrosed tissue may be absorbed and replaced by normal tissue or by cicatricial tissue. It may form a caseous mass, or the cavity may fill with lymph, forming a cyst.
