| primordial | 1. First in order; primary; original; of earliest origin; as, primordial condition. "The primordial facts of our intelligent nature." 2. <geology> Of or pertaining to the lowest beds of the Silurian age, corresponding to the Acadian and Potsdam periods in American geology. It is called also Cambrian, and by many geologists is separated from the Silurian. 3. <biology> Originally or earliest formed in the growth of an individual or organ; as, a primordial leaf; a primordial cell. <botany> Primordial utricle, the interior lining of a young vegetable cell. Origin: L. Primordialis, from primordium the first beginning; primus first + ordiri to begin a web, to begin: cf. F. Primordial. Source: Websters Dictionary (01 Mar 1998) |

| primordial cartilage | Cartilage in an early stage in its development. (05 Mar 2000) |
| primordial cell | A cell from a group that constitutes the primordium of an organ or part of the embryo. (05 Mar 2000) |
| primordial dwarfism | Dwarfism characterised by normal development that is at a strikingly lesser rate than that for members of the same family, race, or other races. Synonym: primordial dwarfism, true dwarfism. (05 Mar 2000) |
| primordial germ cell | The most primitive undifferentiated sex cell, found initially outside the gonad. Synonym: gonocyte. (05 Mar 2000) |
| primordial gigantism | Unusually large size from birth due to familial or genetic factors or intrauterine environment (e.g., maternal prediabetic state) and not to hyperpituitarism. (05 Mar 2000) |
| primordial kidney | 1. The definitive excretory organ of primitive fishes. Synonym: head kidney. 2. In the embryos of higher vertebrates, a vestigial structure consisting of a series of tortuous tubules emptying into the cloaca by way of the primary nephric duct; in the human embryo, the pronephros is a very rudimentary and temporary structure, followed by the mesonephros and still later by the metanephros. Synonym: forekidney, primordial kidney. Origin: pro-+ G. Nephros, kidney (05 Mar 2000) |
| primordial ovarian follicle | A follicle in which the primordial oocyte is surrounded by a single layer of flattened follicular cells. (05 Mar 2000) |
| adrenal cyst | <radiology> Same characteristics as renal cysts, but less common, thick wall, septations, calcifications suggests pseudocyst (12 Dec 1998) |
| adventitious cyst | 1. An accumulation of fluid in a cystlike loculus, but without an epithelial or other membranous lining. Synonym: adventitious cyst, false cyst. 2. A cyst whose wall is formed by a host cell and not by a parasite. 3. A mass of 50 or more Toxoplasma bradyzoites, found within a host cell, frequently in the brain; formerly called a pseudocyst, but now considered a true cyst enclosed in its own membrane within the host cell that may rupture to release particles that form new cysts, and apparently is infective to another vertebrate host. See: bradyzoite. Origin: pseudo-+ G. Kystis, bladder (05 Mar 2000) |
| allantoic cyst | Cyst occurring in a persistent portion of the urachus, presenting as an extraperitoneal mass in the umbilical region. It is characterised by abdominal pain, and fever if infected. It may rupture, leading to peritonitis, or it may drain through the umbilicus. (12 Dec 1998) |
| alveolar hydatid cyst | A hydatid cyst of a multiloculate type, usually in the liver, caused by Echinococcus multilocularis, adults of which are in foxes; larvae (alveolar hydatid) are found chiefly in microtine rodents, but also among humans such as trappers and others handling pelts of infected foxes and other carnivores; growth is by exogenous budding and is not limited by an outer laminated membrane as in the hydatid cyst from E. Granulosus; necrosis, cavitation, contiguous spread, and death usually ensue. Synonym: multilocular hydatid cyst, multiloculate hydatid cyst. (05 Mar 2000) |
| aneurysmal bone cyst | <radiology> ABC, 10 - 30 yrs, 75% before skeletal maturity, sites: long bones; also, flat bones Findings: metaphyseal if unfused, metaepiphyseal after fusion, lytic, expansile, thin, continuous rim, thin internal bony strands (12 Dec 1998) |
| angioblastic cyst | Mesenchymal tissue capable of forming blood in the embryo. (05 Mar 2000) |
| apical periodontal cyst | An inflammatory odontogenic cyst derived histogenetically from Malassez' epithelial rests surrounding the root apex of a nonvital tooth. Synonym: periapical cyst, radicular cyst, root end cyst. (05 Mar 2000) |
| primordial cyst |
a relatively uncommon type of odontogenic cyst that develops through cystic degeneration and liquefaction of the stellate reticulum in an enamel organ before any calcified enamel or dentin has been formed. Such cysts originate from supernumerary teeth, and are found in place of a tooth rather than being associated with one.
