sebaceous gland
oil-secreting gland in dermis that is associated with hair follicles
sebum
oily substance secreted by sebaceous glands
startum corneum
outermost layer of the epidermis, which consists of flattened, keratinized cells
bacterial analyses
samples of skin are examined for presence of microorganisms
fungal tests
scrapings from skin lesions, hair specimens, or nail clippings are sent to a laboratory for culture and microscopic identification os fungal infection
cryosurgery
use of subfreezing temperature achieved with liquid nitrogen application to destroy tissue
curettage
use of a sharp dermal curette to scrape away a skin lesion
electrodesiccation
tissue is destroyed by burning with an electric spark
mohs surgery
thin layers of malignant tissue are removed, and each slice is examined microscopically to check for adequate extent of resection
skin biopsy
suspicious skin lesion are removed to sampled and examined microscopically by a pathologist
skin test
substances are injected intradermally or applied to the skin, and results are observed
ABDCE
Asymmetry (of shape), border (irregularity), color (variation within one lesion), diameter (greater than 6 mm), evolution (change)- characteristics associated with melanoma
BCC
basal cell carcinoma
DLE
discoid lupus erythematosus
PPD
