Skin Lesion Pictures
vascular lesions
involving blood under the skin either in vessels or outside
bulla
larger vesicle
words to describe distribution of a rash/lesion
extent - isolated, localized, regionalized, generalized pattern - symmetrical, intertriginous area, random characteristic pattern
plaque
flat top elevated palpable solid lesion greater than 1 cm
HPV virus lesion
grouped clustered lesion
circumscribed lesion
has a distinct shape
scale
heaped up keratinized cells, flaky, white
telangiectasia
in the plane of the skin, small blood vessels becoming enlarged and showing through skin, usually in a large area
patch
large, discolored, non-palpable (birthmark)
crust
leakage of serous fluid onto epidermis and dries, usually after the end of purulence
fissure
linear crack in skin, epidermis and possibly dermis
poison ivy
linear lesion
excoriation
linear loss of epidermis (scratching)
petechiae
non-blanching reddish macules or papules representing extravascular deposits of blood, less than 0.3 cm
purpura
non-blanching reddish macules or papules, greater than 0.3 cm
nodule
palpable, round solid lesion greater than 1 cm, difference from plaque more vertical breadth as opposed to horizontal
lesions that occur outside blood vessels
petechiae, purpura, ecchymosis, hematoma, do not blanch!
pustule
pus-filled vesicle, indicates infection
tumor
raised lesion 1-2 cm in diameter and depth
scar
skin grows back over lesion, a little raised
erosion
superficial depression in skin (usually only epidermis) more spread out than a linear fissure
pressure sores
sustained compression obliterating cap blood flow to skin --> necrosis. also from shear forces by moving body across sheets for example. friction and moisture increase risk
lichenification
thickening of skin with exaggerated markings from excessive scratching, psoriasis
atrophy
thinning of skin surface, shiny
striae
type of skin atrophy, stretch marks, can be associated with prolonged admin of cortisone compound, excessive natural cortisol, metabolic disease, Cushing syndrome
wheal
various size, fluctuant as opposed to solid but not really fluid in them, urticaria or hives
lesions that blanch
vascular lesions, occur in vessels
lesions with fluid inside
vesicles, bulla, pustules
cellulitis
dermal and subQ infection, bright red, warm, tender skin
papule
elevated, solid lesion less than 1 cm (nevus or mole)
3 secondary lesions
erosion, ulcer, fissure
vesicles
circumscribed, elevated lesion less than 1 cm and contains serous or hemorrhagic fluid (blister)
macule
circumscribed, non-palpable discoloration of skin that is less than 1cm (freckle)
ulcer
deeper loss of epidermis and dermis, red or reddish blue
hemangioma
dense often raised cluster of blood vessels, benign tumor
ring worm
annular lesion
