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 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
