| abscess | <microbiology, surgery> A localised collection of pus caused by suppuration buried in tissues, organs or confined spaces. Usually due to an infective process. Origin: L. Abscessus, from ab = away, cedere = to go (18 Nov 1997) |

| abscess scan | <investigation> This is a nuclear scan that utilises radioactively tagged white blood cells. The patients white blood cells (taken from a small tube of blood) are tagged with radioactive indium. Later, the cells are then reinjected into the bloodstream. The coarse of the white blood cells can then be mapped using a gamma camera (radiation detecting device). The net result is a picture that shows the location of the radioactive white blood cells. The location of the white cells can indicated the presence of infection or inflammation. This test is useful in detecting a hidden source of bacterial infection, such as an abscess. (11 Mar 1998) |

| anorectal abscess | <surgery> An abscess that forms adjacent to the anal opening. Symptoms include a tender swelling adjacent to the anus and pain on defecation. (27 Sep 1997) |
| apical abscess | <dentistry> A dental abscess that occurs at the end of a root, caused by tooth decay which invades the pulp chamber of the tooth.

These infections must be treated by root canal therapy (endodontics) or tooth extraction. (27 Sep 1997) |
| appendiceal abscess | An intraperitoneal abscess, usually in the right iliac fossa, resulting from extension of infection in acute appendicitis, especially with perforation of the appendix. Synonym: periappendiceal abscess. (05 Mar 2000) |
| areolar gland abscess | An abscess or growth on the areolar gland (located beneath the areola) in the breast. most often perceived as a tender, painful lump that may drain pus. Incision and drainage is often required. The early application of warm wet compresses and antibiotics can be helpful in avoiding large abscess formation. (27 Sep 1997) |
