Pallor
|
(pale appearance)
Anemia – decreased hct Shock – decreased perfusion/vasoconstriction Albinism – whitish pink, absence of pigment Vitiligo – patchy milky white spots |
|
Cyanosis
|
Build up of unoxygenated blood (dusky blue)
Central – chronic heart lung disease Peripheral – exposure to cold, anxiety (nail beds dusky) |
|
Erythema
|
Hyperemia – increased blood flow, from inflammation/fever/booze/blushing (red/pink)
Polycythemia – increased red blood cells, capillary statis (ruddy blue in face) Carbon monoxide poisining – bright cherry red in face and upper torso Venous statis – decreased blood flow form area, engorged venules (dusky rubor) |
|
Jaundice
|
Increased serum bilirubin, after severe burns/infections (yellow in sllera, hard palate, musucs membranes, then over skin)
Carotenemia – increased serum carotene from ingestion of carotene-rich (yellow-orange forehead, palms, soles) Uremia – renal failure causing retained urochrome pigments (orange-green or gray) |
|
Brown-Tan
|
Addison’s Disease – cortisol deficiency (bronzed, eternal tan)
Café au Lait Spots – caused by increased pigment basal layer (tan to light brown, irregularly shaped, oval patch, well defined borders) |
|
Annular
|
circular, begins in center and spreads to periphery (tinea cororis=ringworm, tinea versicolor, pityriasis rosea)
|
|
Confluent
|
lesions run together (big ole area) (urticaria hives)
|
|
Discrete
|
distinct, individual lesions that remain separate (molluscum) (a mole)
|
|
Grouped
|
clusters of legions (vesicles of contact dermatitis) (new soap, bunch of bumps develop from contact to that area)
|
|
Gyrate
|
twisted, coiled spiral, snakelike
|
|
Target
|
or iris, resembles iris of eye, bullseye, round with wide dot in middle
|
|
Linear
|
a scratch, streak, line, or stripe
|
|
Zosteriform
|
linear along a nerve route (herpes zoster)
|
|
Polycyclic
|
annular lesions grow together (lichen planus, psoriasis)
|
|
Macule
|
discoloration, flat, circumscribed, < 1cm. (freckle) usually brown
|
|
Patch
|
macules >1cm (Mongolian spot, vitiligo, café au laiet spot, choasma, measles rash)
|
|
Papule
|
ELEVATED solid lesion 0.5 to < 1cm in diameter, color varies (mole)
|
|
Plaque
|
papules coalesce to form surface elevation >1cm, plateau-like, disk-shaped lesion (psoriasis, lichen planus)
|
|
Nodule
|
circumstribed, elevated, solid lesion >1cm (fibroma)
|
|
Tumor
|
solid, elevated, hard or soft, >1cm, may extend deeper in dermis than papule (xanthoma, fibroma, intradermal nevi)
|
|
Pustule
|
circumscribed collection of leukocytes and free fluid (pussy), varies in size (acne)
|
|
Vesicle
|
circumscribed, free fluid (CLEAR), <1cm (blister)
|
|
Bullae
|
circumscribed collection of free fluid, >1cm (contact dermatitis)
|
|
Wheal
|
firm, edematous plaque, from infiltration of the dermis with fluid (TB test, hive, mosquito bite)
|
|
Urticaria (Hives)
|
wheals coalesce to form extensive reaction, intensely pruritic (severe itching)
|
|
Cyst
|
encapsulated, fluid-filled cavity of dermis or subq, tensely elevated skin (sebaceous syst, wen)
|
|
Crust
|
thickened, dried out eudate left after vesicles/pustules burst or dry up
|
|
Scale
|
compact, desiccated flakes of skin, dry or greasy, solvery or white from shedding of dead keratin
|
|
Fissure
|
linear crack with adrupt edges, extends into dermis, dry or moist (cheilosis at corners of mouth, athelete’s foot)
|
|
Erosion
|
Scooped out but shallow depression. Superficial, epidermis lost, moist but no bleeding, hels without scar since erosion doesn’t extend into dermis.
|
|
Ulcer
|
deeper depression, extending into dermis, irregular shape, may bleed, leaves scar (statis ulcer, pressure sore, chancre)
|
|
Excoriation
|
self-inflicted abrasion, superficial. Scratches from intense itching (insect bites, scabies dermatitis, varicella
|
|
Scar
|
after a skin lesion is repaired, norm tissue is lost, replaced by CT, permanent
|
|
Atrophic scar
|
resulting skin level depressed with loos of tissue (thinning of epidermis)
Lichenification: prolonged, intense scratching, eventually thickens, produces tightly packed papules, looks like surface of moss (lichen) |
|
Keloid
|
a hypertrophic scar. Elevated by excess scar tissue (Frankenstein) (smooth, rubbery, clawlike, more in Blacks)
|
