| 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) |
| fibrous dysplasia of bone | A disease of bone marked by thinning of the cortex and replacement of bone marrow by gritty fibrous tissue containing bony spicules, producing pain, disability, and gradually increasing deformity. Only one bone may be involved (fibrous dysplasia, monostotic) or several (fibrous dysplasia, polyostotic). (12 Dec 1998) |
| fibrous dysplasia of jaws | <radiology> Hereditary form of polyostotic fibrous dysplasia, involves mandible (12 Dec 1998) |
| fibrous dysplasia, polyostotic | Fibrous dysplasia of bone affecting several or many bones. When associated with melanotic pigmentation of the skin and endocrine disorders, it is known as albright's syndrome. (12 Dec 1998) |
| florid osseous dysplasia | Benign fibro-osseous jaw lesions of unknown aetiology, occurring predominantly in middle-aged black females, which present as large painless radiopaque masses usually involving several quadrants of the jaw. Synonym: florid osseous dysplasia, cemental dysplasia. (05 Mar 2000) |
| lymphopenic thymic dysplasia | An obsolete term for thymic alymphoplasia. (05 Mar 2000) |
