HIGH YIELD Flashcards
typical NT that thermoregulates?
Ach
three histological features?
desquamation
infiltration
erythema
name this?
common chronic inflammatory disease
plaques
beta blockers, lithium and terbinifine are RFs
psoriasis
pathology of psoriasis?
epidermal hyperplasia
neutrophils in the stratum corneum and epidermis
microabcesses of neutrophils
psoriasis management?
salicylic acid, corticosteroids, and tars
calcipotriene
halobestasol

what are the exacerbations of psoriasis?
psychological stress
smoking
aggravating drugs
- betablockers
- penicillin
- terbinafine
can take weeks to months after d/c of causative drug
thickening of skin with some scaling secondary to repetitive scratching or rubbing
-not a unique disease but a reaction pattern
localized itching sensation in a specific area of skin like from an orthotic or repetitive scratching
histopathologists report pedal corns as localized lichen simplex chronicus
lichen simplex chronicus
erythematous, scaling, lichenified plaques
chronic lesions may exhibit central hypo pigmentation
what is this?
acte and chronic LSC
what is this?
butterfly sign, not common
varied nodules
prurigogenic cytokine
prurigo nodularis
thus, darkly pigmented skin is most susceptible to hypo pigmentation and depigmentation and so what do we do to patient?
what exaggerates effects?
warn them
depositing within subq layer

- hard keratosis
- typically PIPJ 2nd toe
- distal plantar lateral aspect of mallet toes
heloma mole
- soft keratoses
- interdigital 4th and 5th toes
- localized LSC
listers corn
-focal pressure keratosis
neuromuscular corn
-fibrosis with entrapped nerve fibers
what is this?
known as knuckle pads
pressure aggravated
heloderma
what is this?
symmetric eruption of hyper pigmented, velvety cutaneous thickening
develops anywhere
associated obesity, hypothyroidism, acromegaly
acral acanthotic acanthosis nigricans
excess insulin like growth factors
what is this?
aural acanthosis nigricans
pressure induced pedal hyperkeratoses
-small, nucleated, adjacent to bony prominence
- lymphedema keratoderma
- arsenical keratosis
- keratoderma climactericum
what is this?
plantar hyperkeratosis
