301 Test 2 skin (jarvis) Flashcards
lesion shapes, circular lesions that begin in center and spread to periphery
annular
lesion shapes, lesions that run together
confluent
lesion shapes, individual lesions that remain separate
discrete
lesion shapes, clusters of lesions
grouped
lesion shapes, twisted, coiled spiral
gyrate
lesion shapes, concentric rings
iris or target
lesion shapes, streak
linear
lesion shapes, annular lesions that grow together
polycyclic
lesion shapes, linear arrangement along a nerve route
zosteriform
Only a color change, flat, less than 1 cm (freckle)
macule
Macule larger that 1 cm
patch
palpable, elevated lesion less than 1 cm
papule
papule greater than 1 cm
plaque
solid, elevated, hard or soft lesion larger than 1 cm. May extend deeper into dermis than a papule
nodule
lesions larger than a few cm, deeper in dermis, firm or soft
tumor
superficial, raised, transient, red, irregular shape caused by edema
wheal
wheals that coalesce to form extensive reaction; pruritic
urticaria (hives)
elevated cavity containing free clear fluid, up 1 cm
vesicle
pus cavity
pustule
encapsulated fluid filled cavity in dermis
cyst
thickened, dried out exudate left when vesicles burst
crust
compact desiccated flakes of skin from shedding dead excess keratin
scale
linear crack with abrupt edges, extends into dermis
fissure
scooped out but shallow depression, superficial lesion, no bleeding
erosion
self-inflicted abrasion (from itching)
excoriation
resulting skin level depressed with loss of tissue; thinning of epidermis
atrophic scar
prolonged intense scratching eventually thickens the skin and produces tightly packed sets of papules: looks like surface of moss
lichenification
hypertrophic scar (smooth, rubbery, claw like)
keloid
