Transplantation from a foreign donor (a pig) and transferred to a human; aka heterograft
Allergy Skin Test
Any test in which a suspected allergen or sensitizer is applied to or injected into the skin to determine the patient’s sensitivity to it
Intradermal
Skin test that identifies suspected allergens by subcutaneously injecting small amount of extracts of the suspected allergens and observing the skin for a subsequent reaction
Patch
Skin test that identifies allergic contact dermatitis by applying a suspected allergen to a patch which is then taped on the skin, usually forearm, and observing the area 24 hours later for an allergic response
Scratch
Skin test that identifies suspected allergens by placing a small quantity of the suspected allergen on a lightly scratched area of the skin; also called puncture or prick test
Culture and Sensitivity
Laboratory test that grows a colony of bacteria removed from an infected area(such as an ulcer, wound, or pus from an infection) in order to identify the specific infecting bacterium and then determine its sensitivity to antibiotic drugs
Vitiligo
Localized loss of skin pigmentation characterized by milk-white patches
Chemical peel
Chemical removal of the outer layers of skin to treat acne scarring and general keratoses; aka chemabrasion
Cryosurgery
Use of subfreezing temperature (liquid nitrogen) to destroy or eliminate abnormal tissue, such as tumors, warts, and unwanted, cancerous, or infected tissue
Debridement
Removal of necrotized tissue from a wound by surgical excision, enzymes, or chemical agents
Dermabrasion
Rubbing using wire brushes or sandpaper to mechanically scrape away the epidermis
Urticaria
Allergic reaction of the skin characterized by the eruption of pale red, elevated patches called wheals or hives
Verruca
Epidermal growth caused by a virus; aka warts
Petchia
Minute, pinpoint hemorrhage under the skin
pressure ulcer
inflammation, sore, or skin deterioration caused by prolonged pressure from lying in one position that prevents blood flow to the tissues, usually in elderly, bedridden persons
pruritus
intense itching
psoriasis
Chronic skin disease characterized by circumscribed red patches covered by thick, dry, silvery, adherent scales and caused by excessive development of the basal layer of the epidermis
Purpura
Any of several bleeding disorders characterized by hemorrhage into the tissues, particularly beneath the skin or mucous membranes, producing ecchymoses or petechiae
