These terms imply necrosis or loss of tissue, generally of a progressive character.' The loss of tissue may be rapid, and involve the formation of visible sloughs, or it may be gradual, a molecular necrosis, the dead particles being absorbed or removed in the exudation. These results are produced by very intense irritants, and the inflammations are usually of an infective and suppurative character. While ulceration expresses the process of progressive destruction of tissue, the ulcer is the open exposed gap in the tissue. If the ulceration pauses, then the ulcer becomes covered with granulations and is converted into a granulating wound.
