| nephroma, mesoblastic | A malignant tumour of the kidney characterised by spindled myofibroblastic cells arranged in sheets or bundles with a tendency to infiltrate into the adjoining normal kidney and through the capsule into the perirenal tissues. While it appears on gross examination to be circumscribed, partial excision is usually unsuccessful and total removal is recommended. (12 Dec 1998) |
| multilocular cystic nephroma | <radiology> Cystic hamartoma, cystadenoma, congenital, usually benign, multiple small, noncommunicating cysts in single renal mass, usually large (mean 10 cm), with or without calcification, 50% detected in childhood, remainder in older adults, kids: M more than F, adults: F more than M (12 Dec 1998) |

| mesoblastic segment | 1. <zoology> One of the actual or ideal serial segments of which an animal, especially. An articulate or vertebrate, is is composed; somatome; metamere. Somitic. 2. <embryology> Segmentally arranged blocks of mesoderm lying on either side of the notochord and neural tube during development of the vertebrate embryo. Somites are formed sequentially, starting at the head. Each somite will give rise to muscle from the myotome region), spinal column (from the sclerotome) and dermis (from dermatome). (04 Mar 1998) |
| mesoblastic sensibility | The sensation felt in muscle when it is contracting; awareness of movement or activity in muscles or joints; sense of position or movement mediated in large part by the posterior columns and medial lemniscus. See: bathyesthesia. Synonym: deep sensibility, kinesthetic sense, mesoblastic sensibility, muscular sense, myoesthesis, myoesthesia. Origin: G. Mys, muscle, + aisthesis, sensation (05 Mar 2000) |
| adrenal hyperplasia, congenital | A group of inherited disorders of adrenal steroidogenesis, the physical expression of which varies with the sex of the patient, the severity of the congenital enzyme defect, and the age at which the defect makes its presence felt. The most common form, the simple virilizing form, is due to a 21-hydroxylase deficiency. There is also a salt-losing form (a more complete 21-hydroxylase deficiency), a hypertensive form (11-hydroxylase deficiency), a 17-hydroxylase deficiency form, a desmolase deficiency form, and a 3-beta-hydroxysteroid deficiency form.

| 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) |
