viral skin infections and viral xanthems Flashcards
all warts are caused by
HPV
the only reason you biopsy a genital wart is to
check for cancer
30-40 types of HPC produce
anogenital warts
15-20 types of HPV are
cancerous
in F<30, HPV is
transient
in F>30, HPV is
persistant and can turn to cervical cancer
what do you protect HPV with
gardasil
appearance of warts
raised projection with blood vessels
uniform mosaic pattern from above
hyperkeratotic surface with papillomatosis
scale removal of warts shows
punctuate vessels (vs corn which has smooth base)
non-uniform pattern found in
seborrheic keratosis
plantar warts
similar to corn/callus, but their base with punctuated microhemorrhages is diagnostic
*remove only if painful
digitate warts
digits, occurs on thin skin surface
genital warts
warts spread rapidly on moist mucous surfaces, but are also easy to treat
plane or flat warts
hard to treat
anal warts in kids
suspect abuse
seborrheic keratosis
benign skin growth- not viral
pearly penile papules
anatomy variant of normal (angiofibroma) that may wart
molluscum contagiosum
multiple dome shaped pink papules
umbillicated and contain a caseous plug
what type of virus is molluscum contagiousum
poxvirus
when do you frequently get molluscum
on chapped, eczema skin–>spreads–>treat eczema first
xanthem
skin eruption bursting with blood
wide=spread, symmetric, erythematous, discrete or confluent macules and papules that initally do not form scale
FIfth disease
URI symptoms cuased by B19 parovirus
5th disease erythema patterns
facial- slapped cheap (spare nasolabial folds)
net pattern erythema- begins on extremities, 2 days after onset of facial erythema to trunks and buttocks
when does net pattern fade
6-14 days
