|---|---|
| epiderma | 1. <dermatology> The basal layer of the mammalian epidermis contains cells that undergo repeated divisions. The cells outwards from a particular basal cell are often derived from this cell or a nearby one so that columns of cells exist running outwards from the stem cell in the basal layer from which they were derived. Such columns of cells are referred to as proliferative units. 2. <biology> Outer epithelial layer of a plant or animal. May be a single layer that produces an extracellular material (as for example the cuticle of arthropods) or a complex stratified squamous epithelium, as in the case of many vertebrate species. (18 Nov 1997) |
| 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) |
| epidermalization | The transformation of glandular or mucosal epithelium into stratified squamous epithelium. Synonym: epidermalization. (05 Mar 2000) |
| epidermatoid | <anatomy> Epidermoid. Origin: Gr. Upon +, skin. Cf. Epidermoid. Source: Websters Dictionary (01 Mar 1998) |
| epidermatoplasty | Rarely used term for skin grafting by means of strips or small patches of epidermis with the underlying outer layer of the corium. Origin: epidermis + G. Plastos, formed (05 Mar 2000) |
| epidermic | Epidermal; connected with the skin or the bark. <medicine> Epidermic administration of medicine, the application of medicine to the skin by friction. Origin: Cf. F. Epidermique. Source: Websters Dictionary (01 Mar 1998) |

| epidermal cyst |
a benign cyst derived from the epidermis or the epithelium of the hair follicle, which is formed by cystic enclosures of epithelium within the dermis that become filled with keratin admixed with variable amounts of lipid-rich debris. The two main types are epidermal inclusion c. and pilar c., with dermoid c. and steatocystoma multiplex being less common variants. Called also epidermoid c., sebaceous c., and wen.

| epidermoid cyst |
1. epidermal c. 2. a benign tumor formed by inclusion of epidermal elements, especially at the time of closure of the neural groove and located in the skull, meninges, or brain (see intracranial cholesteatoma ); it may grow gradually because of accumulations of desquamated debris and may become calcified. Called also epidermoid, epidermoidoma, and epidermoid tumor.
