Referring to the thin outermost layer of the skin, itself made up of several layers, that covers and protects the underlying dermis (skin).

epidermal

pertaining to or emanating from epidermis.

epidermal appendage
see hair, claw, hoof, horn, chestnut (1), ergot2, dewclaw, comb, wattle, spur (3), pad, footpad, beak, frontal process, feather (1), cere, scale, fin, antler, bristle (1), wool, mohair, cashmere, angora.
epidermal clefts
slit-like discontinuities in the epidermis that do not contain fluid.
epidermal collarette
a feature of a skin lesion, consisting of an encircling rim of epidermal scale with the free edge toward the central area. May represent the margins of an earlier bulla, vesicle or pustule. Characteristic of bullous pemphigoid.
epidermal crust
a consolidated mass of cellular debris, dried exudate, serum, hair, epidermophytic hyphae. Usually is dry and crumbly but in parakeratosis may have a greasy feel about it.
epidermal cyst, epidermoid cyst
an intradermal or subcutaneous cyst containing keratinizing squamous epithelium. It arises from occluded hair follicles. Called also infundibular cyst, wen.
epidermal dysplasia
abnormal development of individual cells of the epidermis. In West Highland white terriers, a familial skin disease characterized by seborrhea, pruritus, alopecia and lichenification from an early age. Infection by Malassezia spp. is a common feature. See also inherited epidermal dysplasia of calves.
epidermal growth factor
a potent growth factor for both epithelial and fibroblast cells.
epidermal lacunae
see epidermal clefts (above).
epidermal laminae
structures formed of epidermal pegs; part of the interdigitating structure between the dermis and the epidermis. Called also epidermal ridges.
epidermal limbi
the layer of soft, light-colored horn that covers the outer side of the coronary border and merges with the horn of the hoof.
epidermal-melanin unit
a melanocyte and adjacent keratinocytes.
epidermal necrolysis
see toxic epidermal necrolysis.
epidermal nibbles
focal areas of epidermal edema, eosinophils and necrosis; suggestive of ectoparasite injury to the skin.
epidermal papilla
a knob-like projection of the epidermis into the dermis; a touch receptor. Called also tylotrich pad and haarscheiben.
epidermal pegs
see rete pegs.
epidermal renewal time
see keratinocyte transit time.
epidermal ridge
see rete ridge.

Observations under the transmission electron microscope showed that the cells forming the apical epidermal cap, when migrating to the amputated extremity of the fin, emitted cytoplasmatic prolongations (Figures 2 and 3), that left spaces between one cell and another (Figures 2 and 3).
The microscopic qualitative features on the adaxial and abaxial epidermis which have been considered include: epidermal cell shape and cell wall sinuousity from a front paradermal view; type, location and distribution of stomata; trichomes shape, size and distribution.

To analyze the results, T-test was used to compare two means, and analysis of variance (ANOVA) was used to compare the measure of the epidermal papillae of the thoracic limb, pelvic limb, the coronary corium and laminar corium of the abaxial wall and sole at a 5 % significance level, according to Sampaio (2010).

Results: Two of the patients had Stevens-Johnson syndrome, four had Stevens-Johnson syndrome/toxic epidermal necrolysis overlap, and five had toxic epidermal necrolysis.
