per·i·ton·sil·lar abscess (p r  -t n s -lr)n. An abscess formed usually above and behind the tonsil, due to extension of infection beyond the tonsillar capsule. Also called quinsy. |
peritonsillar abscess
Etymology: Gk, peri + L, tonsilla, tonsil, abscedere, to go away
an infection of tissue between the tonsil and pharynx, usually after acute follicular tonsillitis. The symptoms include dysphagia, pain radiating to the ear, and fever. Redness and swelling of the tonsil and adjacent soft palate are present. Treatment includes antibiotics, warm saline solution irrigation, incision and drainage with suction if there is no spontaneous rupture of the abscess, and sometimes tonsillectomy. Also called quinsy. Compare parapharyngeal abscess, retropharyngeal abscess. See also tonsillitis.
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. 
Abscess, cross section.
alveolar abscess a localized suppurative inflammation of tissues about the apex of the root of a tooth.
amebic abscess an abscess cavity of the liver resulting from liquefaction necrosis due to entrance of Entamoeba histolytica into the portal circulation in amebiasis; amebic abscesses may also affect the lungs, brain, and spleen.
Bartholin abscess acute infection of a Bartholin gland with symptoms including pain, swelling, cellulitis of the vulva, and dyspareunia. Treatment is incision and drainage of the abscess. Cultures should be obtained to rule out infections by Neisseria gonorrhoeae or Chlamydia.
Bezold's abscess one deep in the neck resulting from a complication of acute mastoiditis.

Brodie's abscess a circumscribed abscess in bone, caused by hematogenous infection, that becomes a chronic nidus of infection.
cold abscess one of slow development and with little inflammation, usually tuberculous.
diffuse abscess an uncircumscribed abscess whose pus is diffused in the surrounding tissues.
gas abscess one containing gas, caused by gas-forming bacteria such as Clostridium perfringens. Called also Welch's abscess.
miliary abscess one composed of numerous small collections of pus.
