abscess

 [ab´ses]
a localized collection of pus in a cavity formed by the disintegration of tissue. Abscesses are usually caused by specific microorganisms that invade the tissues, often by way of small wounds or breaks in the skin. An abscess is a natural defense mechanism in which the body attempts to localize an infection and wall off the microorganisms so that they cannot spread throughout the body. As the microorganisms destroy the tissue, an increased supply of blood is rushed to the area. The cells, bacteria, and dead tissue accumulate to form a clump of cream-colored liquid, which is the pus. The accumulating pus and the adjacent swollen, inflamed tissues press against the nerves, causing pain. The concentration of blood in the area causes redness. The abscess sometimes “comes to a head” by itself and breaks through the skin or other tissues, allowing the pus to drain. Local applications of heat may be used to facilitate localization and drainage.
