| oculoauriculovertebral dysplasia | A syndrome characterised by epibulbar dermoids, preauricular appendages, micrognathia, and vertebral and other anomalies. Synonym: Goldenhar's syndrome, OAV syndrome. (05 Mar 2000) |
|---|---|
| oculodentodigital dysplasia | Microphthalmia, coloboma, or anomalies of the iris associated with malformed and malpositioned teeth and with anomalies of the fingers including syndactyly, campylodactyly, or absent phalanges; autosomal dominant inheritance. (05 Mar 2000) |
| oculovertebral dysplasia | Microphthalmia, colobomas, or anophthalmia with small orbit, twisted face due to unilateral dysplasia of maxilla, macrostomia with malformed teeth and malocclusion, vertebral malformations, and branched and hypoplastic ribs. Synonym: oculovertebral syndrome, Weyers-Thier syndrome. (05 Mar 2000) |
| odontogenic dysplasia | A localised arrested tooth development which appears to involve most commonly the anterior teeth, usually on one side of the midline, most often the maxillary central and lateral incisors. Roentgenographically, the teeth have a ghostlike appearance. Calcification and bits of prismatic enamel may be found in the pulp and the enamel is thin and absent in part. (12 Dec 1998) |
| ophthalmomandibulomelic dysplasia | An autosomal dominant disorder with corneal clouding and multiple abnormalities of the mandible and limbs. (05 Mar 2000) |
| thanatophoric dysplasia | A severe form of neonatal dwarfism with very short limbs. All cases have died at birth or in the neonatal period. (12 Dec 1998) |
| ectodermal dysplasia | A hereditary condition (most often x linked) that is characterised by the abnormal development of skin, absence of sweat glands, dry eyes and abnormal development of teeth. Symptoms include absent teeth, peg teeth, inability to sweat, thin skin and heat intolerance. Mucous membrane involvement may result in a foul-smelling nasal discharge. The inability to sweat leads to the inability to maintain normal body temperature in a warm environment. Some may exhibit fevers and will require artificial cooling. Origin: Gr. Plassein = to form (27 Sep 1997) |
| ectrodactyly-ectodermal dysplasia-clefting syndrome | <syndrome> An autosomal recessive disorder resulting in defects of hands and feet; the ectodermal dysplasia causes fair skin, anodontia, and cleft palate. (05 Mar 2000) |
| enamel dysplasia | An autosomal dominant or x-linked disorder in which there is faulty development of the dental enamel owing to agenesis, hypoplasia, or hypocalcification of the enamel. It is marked by enamel that is very thin and friable and frequently stained in various shades of brown. (12 Dec 1998) |
| epithelial dysplasia | A disorder of differentiation of epithelial cells which may regress, remain stable, or progress to invasive carcinoma. (05 Mar 2000) |
| faciodigitogenital dysplasia | A syndrome of ocular hypertelorism, anteverted nostrils, broad upper lip, saddle-bag scrotum, and laxity of ligaments resulting in genu recurvatum, flat feet, and hyperextensible fingers; X-linked and autosomal dominant forms. Synonym: Aarskog-Scott syndrome. (05 Mar 2000) |
| familial white folded dysplasia | An autosomal dominant condition of the oral cavity characterised by soft, white or opalescent, thickened and corrugated folds of mucous membrane; other mucosal sites are occasionally involved simultaneously. Synonym: familial white folded dysplasia, oral epithelial nevus. (05 Mar 2000) |
| fibromuscular dysplasia | <radiology> Beaded segment of artery, medial type most common, F more than M, renal arteries, most common vessels, R more than L, mid and distal 1/3 (Differential diagnosis: atherosclerosis - ostium/proximal) (12 Dec 1998) |
| fibrous dysplasia | A condition of cystic bone growth that results from abnormal bone development. May occur with bone lesions, skin pigmentation and endocrine abnormalities. See: McCune-Albright syndrome. Origin: Gr. Plassein = to form (27 Sep 1997) |
| fibrous dysplasia, monostotic | Fibrous dysplasia of bone involving only one bone. (12 Dec 1998) |
