cyst

1. a closed epithelium-lined sac or capsule containing a liquid or semi-solid substance. Most cysts are harmless but they occasionally may change into malignant growths, become infected, or obstruct a gland. There are four main types of cysts: retention cysts, exudation cysts, embryonic cysts and parasitic cysts. See also specific locations and organs.

2. a stage in the life cycle of certain parasites, during which they are enveloped in a protective wall. See also cystic.

aneurysmal cyst

see bone cyst.

blood c's

these are found in the carcasses of poultry at meat inspection. They are small round cystic lesions containing blood. They are hemangiomas.

branchial cyst, branchiogenic cyst, branchiogenous cyst

one formed from an incompletely closed branchial cleft. See also branchial cyst.

cervical c's

retention cysts of glands in the uterine cervix in the cow, are palpable as fluctuating masses on rectal examination. Called also nabothian cyst or follicle.

chocolate cyst

one filled with hemosiderin following local hemorrhage.

cutaneous cyst

see epidermal cyst, dermoid cyst, follicular cyst, sebaceous cyst.

daughter cyst

one that develops within a parent cyst, e.g. hydatid cyst.

dentigerous cyst

see dental cyst.

echinococcus cyst

hydatid cyst.

embryonic cyst

one developing from bits of embryonic tissue that have been overgrown by other tissues, or from developing organs that normally disappear before birth. An example is a branchial cyst.

epidermal inclusion cyst

see epithelial inclusion.

exudation cyst

a cyst formed by the slow seepage of an exudate into a closed cavity.

fatty cyst

formed when fat accumulates in large amounts and the cells break down forming a central mass of lipid surrounded by a multinuclear rim.

follicular cyst

one due to occlusion of the duct of a follicle or small gland, especially one formed by enlargement of a graafian follicle as a result of accumulated transudate.

Gartner's duct cyst

see cystic gartner's ducts.

horn cyst

intracutaneous cystic accumulations of keratin. Seen in trichoepitheliomas and basal cell tumors. Called also keratin cyst.

hybrid cyst

one combining elements of epidermoid and trichilemmal cysts.

hydatid cyst

the larval stage (metacestode) of the tapeworms Echinococcus granulosus and E. multilocularis. See also hydatid disease.

inclusion cyst

see epidermal cyst.

interdigital c's

see pododermatitis; interdigital pyoderma.

keratin cyst

one arising in the pilosebaceous apparatus, lined by stratified squamous epithelium and containing largely macerated keratin and often sufficient sebum to render the contents greasy and often rancid.

lateral cervical cyst

see branchial cyst.

luteal c's

develop from ovarian follicles which fail to rupture but have a lining of luteal cells. Anestrus is the presenting clinical sign.

marine fish c's

worldwide occurrence in fish of round nodules in fibrous capsules; the cause is unknown.

meibomian cyst

see chalazion.

mesenteric cyst

congenital, thin-walled cyst between the leaves of the mesentery; may enlarge and cause colic or even intestinal obstruction.

cyst mites

see laminosioptescysticola.

cyst of Morgagni

see morgagni's hydatid.

nabothian cyst

see cervical cyst (above).

orbital cyst

see mucocele.

ovarian cyst

see cystic ovarian disease.

parasitic cyst

one forming around larval parasites (tapeworms, amebae, trichinae) that enter the body.

pseudohorn cyst

invagination of hyperplastic epidermis; not a true cyst.

retention cyst

a tumor-like accumulation of a secretion formed when the outlet of a secreting gland is obstructed. These cysts may develop in any of the secretory glands—the mammae, pancreas, kidney, salivary or sebaceous glands, and mucous membranes. See also renal retention cysts.

sarcosporidian c's

cylindrical cysts (schizonts) containing bradyzoites, found in the muscles of those infected with Sarcocystis spp.

subconjunctival cyst, conjunctival cyst

misplaced secretory tissue which causes a slowly enlarging, fluctuant subconjunctival mass.

uveal cyst

an acquired or congenital structure which may arise from the iris or the ciliary body. Visible as a mass attached to the iris or may be floating freely in the anterior chamber. Those arising from the ciliary body may not be visible. Seen most commonly in horses. See also iris cyst.

vitelline cyst

a congenital cyst lined with ciliated epithelium occurring along the gastrointestinal canal; the remains of the omphalomesenteric duct.

daughter

1. female offspring.

2. arising from cell division, as a daughter cell.

3. product of the decay or radioactive disintegration of a radionuclide. Usually formed as a result of successive transformations in a series. See also decay (3).
