| carcinoma, adrenal cortical | A malignant neoplasm of adrenal cortical cells demonstrating partial or complete histological and functional differentiation. They are rare, comprising between only 0.05% and 0.2% of all cancers. Women develop functional adrenal cortical carcinomas more commonly than men, but men develop nonfunctioning ones more often than women. Hypercortisolism is the most common presentation for this cancer. Virilism and cushing's syndrome may also result. (12 Dec 1998) |

| paraganglioma, extra-adrenal | A relatively rare, usually benign neoplasm originating in the chemoreceptor tissue of the carotid body, glomus jugulare, and aortic bodies. It consists histologically of rounded or ovoid hyperchromatic cells that tend to be grouped in an alveolus-like pattern within a scant to moderate amount of fibrous stroma and a few large thin-walled vascular channels. They are uncommon before the age of 20, with a female predominance in some series. (12 Dec 1998) |
| medulla of adrenal gland | It is composed principally of anastomosing cords of cells in the core of the gland; the cells display a chromaffin reaction because of the presence of epinephrine and norepinephrine in their granules. Synonym: medulla glandulae suprarenalis, medulla of adrenal gland. (05 Mar 2000) |
| pituitary-adrenal system | The interactions between the anterior pituitary and adrenal glands, in which corticotropin (acth) stimulates the adrenal cortex and adrenal cortical hormones suppress the production of corticotropin by the anterior pituitary. (12 Dec 1998) |
| foetal adrenal cortex | An extensive area of the adrenal gland present in primates during foetal life and for a short period after birth; located between the definitive cortex and the medulla, it contains large steroid-secreting cells arranged in a reticular pattern; involution of this zone in humans is largely completed by three months after birth. Synonym: androgenic zone, foetal reticularis, foetal zone, provisional cortex. (05 Mar 2000) |
| anaemia, dyserythropoietic, congenital | A familial disorder characterised by anaemia with multinuclear erythroblasts, karyorrhexis, asynchrony of nuclear and cytoplasmic maturation, and various nuclear abnormalities of bone marrow erythrocyte precursors. Type II is the most common of the 3 types of congenital dyserythropoietic anaemia; it is often referred to as hempas, based on the hereditary erythroblast multinuclearity with positive acidified serum test. (12 Dec 1998) |
| anaemia, haemolytic, congenital | Haemolytic anaemia due to various intrinsic defects of the erythrocyte. (12 Dec 1998) |
| anaemia, haemolytic, congenital nonspherocytic | Any one of a group of congenital haemolytic anaemias in which there is no abnormal haemoglobin or spherocytosis and in which there is a defect of glycolysis in the erythrocyte. In some cases, pyruvate kinase deficiency has been demonstrated; in other cases, glucose-6-phosphate dehydrogenase deficiency has been demonstrated. (12 Dec 1998) |
| bovine congenital ataxia | An autosomal recessive ataxia seen in several European breeds of cattle. (05 Mar 2000) |
| bullous congenital ichthyosiform erythroderma | Diffusely red, eroded skin at birth, with subsequent scaling, tending to improve in later life, characterised by generalised epidermolytic hyperkeratosis and autosomal dominant inheritance. See: epidermolytic hyperkeratosis. Synonym: generalised epidermolytic hyperkeratosis, ichthyismus hystrix, ichthyosis hystrix. (05 Mar 2000) |
| pain insensitivity, congenital | Absence of sensibility to pain or inability to feel pain. The condition is present at birth. (12 Dec 1998) |
| rubella syndrome, congenital | Transplacental infection of the foetus with rubella usually in the first trimester of pregnancy, as a consequence of maternal infection, resulting in various developmental abnormalities in the newborn infant. They include cardiac and ocular lesions, deafness, microcephaly, mental retardation, and generalised growth retardation. (12 Dec 1998) |
| congenital | <embryology> Existing at and usually before, birth, referring to conditions that are present at birth, regardless of their causation. Origin: L. Congenitus = born together (18 Nov 1997) |
| congenital absence of pulmonary valve | <radiology> BIG central pulmonary arteries, big RV (12 Dec 1998) |
| congenital afibrinogenaemia | <biochemistry> A below normal level of fibrinogen in the plasma. Fibrinogen (factor II) is one of the proteins involved in the formation of a blood clot. This condition may be congenital or acquired (for example disseminated intravascular coagulation, multiple blood transfusions). Origin: Gr. Haima = blood (27 Sep 1997) |
