Intro to Derm- Vocab Flashcards
(25 cards)
<1cm, flat, circumscribed
hypo or hyper pigmented
or can be pink red violet
macule (like a freckle)
> 1cm, flat, circumscribed
hypo or hyper pigmented
or can be pink, red violet
patch (a big macule)
<1cm, elevated, circumscribed
elevation due to increased thickness of epidermis or deposits in dermis
papule (like a pimple)
> 2cm, elevated, circumscribed
involves the dermis and can extend to subQ
great mass below skin surface
nodule
<1cm, elevated, circumscribed, filled with clear fluid
can become pustular, umbilicate or an erosion
vesicle (ex: herpes, or shingles)
> 1cm, elevated, circumscribed filled with clear fluid
bulla
<1cm, elevated, circumscribed, filled with purulent fluid (milky)
pustule
dried serum, blood, pus
crust
hyperkeratosis, accumulation of stratum corneum
scale
linear cleft in skin, painful, due to drying, skin thickening, loss of elasticity
fissure
partial loss of epidermis superficially
erosion
full-thickness loss of epithelium can include dermis/subQ
ulceration
exogenous injury to all or part of epidermis (something rubbing the skin off)
excoriation
thinning of epidermis (leads to wrinkles/shiny appearance
atrophy
thickening of epidermis
lichenification
intercellular edema in epidermis, inflammation
spongiosis
pathology finding in eczema, psoriasis, bulls disorders
incomplete maturation of keratocytes in the epidermal layer; nuclei are retained in stratum corneum
thinning or loss of the granular layer; seen in the plaques of psoriasis and in dandruff
parakeratosis
increased proliferation of granular cells that stick to epidermis
seen with healing wounds. “overgrowth” of tissue beyond the surface of the wound
hypergranulation
loss of intercellular connections
leads to development of vesicles. If there is no “cement” holding the cells together, then fluid leaks out
acantholysis
abnormal development of keratinocytes below stratum granulosum
dyskeratosis
Decreased response to medication after repeated administration
Problem we get when we use steroids too much or they are too high potency
tachyphylaxis
Acute rash developing distant from the primary rash
Cause- Unknown
Id (infectious disease) Reaction/autoeczematization
Skin lesions appearing along trauma lines
Occurs secondary to scratching
koebner phenomenon
Signs of punctate bleeding spots after psoriasis scales are removed
Auspitz Sign
