Definition

connective tissue or collagen

elastic tissue

Term

Term

Abnormal findings

(vascular lesions)

 

Lesions caused by trauma or abuse

Definition
pattern injury, hematoma, ecchymosis (buising)
Term
Annular
Definition
Circular, begins in center and spreads to periphery (e.g. ringworm)
Term
Confluent
Definition
lesions run together (e.g hives)
Term
Discrete
Definition
Distinct, individual lesions that remain separate (e.g molluscum)
Term
Grouped
Definition
Clusters of lesions (e.g vesicles of contract dermatitis)
Term
Gyrate
Definition
( twisted, coiled spiral, snake like)
Term
Target
Definition
resembles iris of eye, concentric rings of color in the lesions (e.g erythema multiforme)
Term
Linear
Definition
a scratch, streak, line or stripe
Term
Polycyclic
Definition
Annular lesions grow together (e.g lichen, planus)
Term
Zosteriform
Definition
linear arrangement along a nerve route (e.g herpes)
Term
Macule
Definition
Solely a color change, flat and circumscribed, or less than 1 cm (e.g. freckles)
Term
papule
Definition
something you can feel, caused by superficial thicknening in the epidermis (e.g elevated nevus (mole)
Term
Patch
Definition
Macules tha are larger than 1cm. E.g mongolian spot, measle rash
Term
plague
Definition
papules coalesce to form surface elevation wider than 1 cm. disk-shaped lesion. (E.g psoriasis, lichen planus.)
Term
nodule
Definition
soild, elevated, hard or soft, larger than 1cm. E.g intradermal nevi (mole)
Term
wheal
Definition
superficial raised, transient, and erythematous, slightly irregular shape due to edema (e.g mosquito bite, allergic reactions)
Term
tumor
Definition
larger than a few centimeters in diameter, firm or soft deeper into dermis. E.g lipoma, hemangioma
Term
urticaria
Definition
wheals coalesce to form extensive reactions, intensely pruritic (hives)
Term
Vesicle
Definition
Elevated cavity containing free fluid up to 1 cm a "blister" leare serum flows if wall is ruptured. ex. herpes simplex, chickenpox, shingles
Term
bulla
Definition
larger than 1 cm diameter usually single chambered. it is thin walled so it ruptures easily. (E.g friction blister, prmphius, burns)
Term
cyst
Definition
excapsulated fluid filled cavity in dermis or subcutaneous layer, tensely elevated skin.
Term
pustule
Definition
turbid fluid (pus) inthe cavity  evevated e.g acne
Term
Crust
Definition
the thcikened, dried-out exudate left when vesicels burst or dry up. color can be red-brown, honey or yellow. (ex. scab after abrasion)
Term
Scale
Definition
compact, desiccated flakes of skin, dray or greasy, silvery or white, from shedding of dead excess keratin cells. ex. eczema, dry skin
Term
fissure
Definition
linear crack with abrupt edges, extends into dermis, dry or moist. ex. athletes foot
Term
erosion
Definition
scooped out but shallow depression. epidermis lost, moist but not bleeding. heals without scar
Term
Ulcer
Definition
deeper depression extending into dermis, irregular shape, may bleed, leaves scar when heals. ex. pressure sore
Term
Excoriation
Definition
self-inflicted abrasion, superficial, sometimes crusted, scratches from intense itching. ex. insect bites, scabies
Term
Scar
Definition
after a skin lesion is repaired, normal tissue is lost and replaced with connective tissue. e.g healed area of surgery or injury, acne
Term
Atrophic scar
Definition
resulting skin level depressed with loss of tissue, a thinning of the epidermis. e.g striae
Term
Lichenification
Definition
prolonged intense scratching eventually thickens the skin and produces tighly packed sets of papules
Term
Keloid
Definition
a hypertrophic scar. resulting skin level is elevated by excess scar tissue, which is invasive beyond the site of original injury. may increase long after healing occurs. loos smooth, rubbery
Term
Skin lesions associated with AIDS
Definition
Epidemic Kaposi's sarcoma
