urticaria

A

allergic reaction of the skin characterized by the eruption of pale red, elevated patches called wheals or hives

25
verruca
epidermal growth caused by a virus - warts
26
vitiligo
localized loss of skin pigmentation characterized by milk-white patches
27
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
28
intradermal allergy skin test
identifies suspected allergens by subcutaneously injecting small amounts of extracts of the suspected allergens and observing the skin for a subsequent reaction
29
patch allergy skin test
identifies allergic contact dermatitis by applying a suspected allergen to a patch, which is then taped on the skin, usually the forearm, and observing the area 24 hours later for an allergic response
30
scratch allergy skin test
identifies suspected allergens by placing a small quantity of the suspected allergen on a lightly scratched area of the skin - puncture test - prick test
31
culture and sensitivity (C&S)
lab test to determine the presence of pathogens in patients with suspected wound infections and identify the appropriate drug therapy to which the organism responds (sensitivity)
32
biopsy (Bx, bx)
representative tissue sample removed from a body site for microscopic examination
33
frozen section (FS) biopsy
ultra thin slice of tissue from a frozen specimen for immediate pathological examination
34
needle biopsy
removal of a small tissue sample for examination using a hollow needle, usually attached to a syringe
35
punch biopsy
removal of a small core of tissue using a hollow punch
36
shave biopsy
removal of elevated lesions using a surgical blade
37
Mohs
procedure that involves progressive removal and examination of layers of cancer-containing skin until only cancer-free tissue remains - micrographic surgery
38
skin graft
transplantation of healthy tissue to an injured site
39
allograft
transplantation of healthy tissue from one person to another person - homograft
40
autograft
transplantation of healthy tissue from one site to another in the same individuals
41
synthetic graft
transplantation of artificial skin produced from collagen fibers arranged in a lattice pattern
42
xenograft
transplantation (dermis only) from a foreign donor (usually a pig) and transferred to a human - heterograft
43
chemical peel
chemical removal of the outer layers of skin to treat acne scarring and general keratosis - chemabrasion
44
cryosurgery
use of subfreezing temperature (commonly liquid nitrogen) to destroy or eliminate abnormal tissue, such as tumors, warts, and unwanted, cancerous, or uninfected tissue
45
debridement
removal of necrotized tissue from a wound by surgical excision, enzymes, or chemical agents
46
dermabrasion
rubbing (abrasion) using wire brushes or sandpaper to mechanically scrape away (abrade) the epidermis
47
fulguration
tissue destruction by means of high-frequency electric current - electrodessication
48
photodynamic therapy (PDT)
procedure in which cells selectively treated with an agent called a photosensitizer are exposed to light to produce a reaction that destroys the cells
49
macule
flat, pigmented, circumscribed area less than 1cm in diameter - freckle - flat mole
50
papule
solid, elevated lesion less than 1 cm in diameter that may be the same color as the skin or pigmented - nervus - wart - pimple

53
pustule
small, raised, circumscribed lesion that contains pus; usually less than 1 cm in diameter - acne - furuncle - pustular psoriasis - scabies
54
tumor
solid, elevated lesion larger than 2cm in diameter that extends into the dermal and subcutaneous layers - lipoma - steatoma - dermatofibroma
55
bulla
vesicle or blister larger than 1 cm in diameter - 2nd degree burns - severe poison oak - poison ivy
56
wheal
elevated, firm, round lesion with localized skin edema that varies in size, shape, and color; paler in the center than surrounding edges; accompanied by itching - hives - insect bites - uticaria
57
excoriations
linear scratch marks or traumatized abrasions of the epidermis - scratches - abrasions - chemical/thermal burns
58
fissure
small slit or crack line sore that extends into the dermal layer; could be caused by continuous inflammation and drying
