| hairy tongue | A tongue with abnormal elongation of the filiform papillae, resulting in a thickened furry appearance. Synonym: glossotrichia, trichoglossia. (05 Mar 2000) |
|---|---|
| neuro-epidermal | <anatomy> Pertaining to, or giving rise to, the central nervous system and epiderms; as, the neuroepidermal, or epiblastic, layer of the blastoderm. Origin: Neuro- + epidermal. Source: Websters Dictionary (01 Mar 1998) |
| oral hairy leukoplakia | A whitish lesion that appears on the side of the tongue and inside cheeks. The lesion appears raised, with a ribbed or hairy surface. Oral hairy leukoplakia occurs mainly in people with declining immunity and may be caused by Epstein-Barr virus infection. (11 Jan 1998) |
| tongue, hairy | A benign condition of the tongue characterised by hypertrophy of the filiform papillae that give the dorsum of the tongue a furry appearance. The colour of the elongated papillae varies from yellowish white to brown or black, depending upon staining by substances such as tobacco, food, or drugs. (12 Dec 1998) |
| toxic epidermal necrolysis | A syndrome in which a large portion of the skin becomes intensely erythematous with epidermal necrosis, and peels off in the manner of a second-degree burn, often simultaneous with the formation of flaccid bullae, resulting from drug sensitivity or of unknown cause; the level of separation is subepidermal, unlike staphylococcal scalded skin syndrome in which there is subcorneal change. Synonym: Lyell's syndrome. (05 Mar 2000) |
| epidermal | Pertaining to or resembling epidermis. Also called epidermic or epidermoid. (18 Nov 1997) |
| epidermal cell | 1. Cell of epidermis in animals. 2. Plant cell on the surface of a leaf or other young plant tissue, where bark is absent. The exposed surface is covered with a layer of cutin. (18 Nov 1997) |
| epidermal cyst | Intradermal or subcutaneous saclike structure, the wall of which is stratified epithelium containing keratohyalin granules. (12 Dec 1998) |
| epidermal growth factor | <growth factor> A mitogenic polypeptide initially isolated from male mouse submaxillary gland. The name refers to the early bioassay, but epidermal growth factor is active on a variety of cell types, especially but not exclusively epithelial. Human equivalent originally named urogastrone owing to its hormone activity. Acronym: EGF (18 Nov 1997) |
| epidermal growth factor receptor protein-tyrosine kinase | <enzyme> The catalytic protein-tyrosine kinase domain found on the cytoplasmic beta-portion of epidermal growth factor receptor. Registry number: EC 2.7.1.- (12 Dec 1998) |
| epidermal growth factor-urogastrone | <chemical> Single chain, nonhelical, acidic polypeptides of about 52 amino acids found in most mammals. Epidermal growth factor and urogastrone are not identical but seem to share biological acivities. They promote growth of, and cell proliferation in, certain tissues, especially epidermal structures and inhibit acid secretion by the stomach. They have been used to treat gastrointestinal ulcers. Chemical name: Epidermal growth factor (12 Dec 1998) |
| epidermal necrolysis, toxic | An exfoliative disease of skin seen primarily in adults and characterised by flaccid bullae and spreading erythema so that the skin has the appearance of being scalded. It results primarily from a toxic reaction to various drugs, but occasionally occurs as a result of infection, neoplastic conditions, or other exposure. (12 Dec 1998) |
| epidermal ridge count | An index of the frequency of sweat pores on the fingertips by enumeration along a set of arbitrarily defined lines; a classic example of a galtonian trait determined almost exclusively by genetic factors. (05 Mar 2000) |
| epidermal ridges | Ridges of the epidermis of the palms and soles, where the sweat pores open. Synonym: cristae cutis, skin ridges. (05 Mar 2000) |
| leukaemia, hairy cell | A neoplastic disease of the lymphoreticular cells which is considered to be a rare type of chronic leukaemia; it is characterised by an insidious onset, splenomegaly, anaemia, granulocytopenia, thrombocytopenia, little or no lymphadenopathy, and the presence of "hairy" or "flagellated" cells in the blood and bone marrow.
