test 2 deck 7 Flashcards
stucco keratosis
dermatosis papulosis nigra
dermatofibroma
what 3 benign tumors are related to UNK?
seborrheic keratosis
dermatosis papulosis nigrans
dermatofibroma
MC site for keloid?
shoulders and chest
what wounds are predisposed to HS/keloid?
predisposed individuals, poor closure post surgery/secondary infection
pink-brown, scaly, hard growth that retracts w/ compression (dimpling), from TRAUMA (shaving, bug bite), collection of fibroblasts, endothelial cells and histocytes, pruritic or tender early. dx. trx prognosis
dermatofibroma
punch bx or exision
R/O MELANOMA, if rapid grow r/o dermatofibrosarcoma protuberans
do skin reoccur?
no
sweat duct tumor, firm flesh colored papule, under eyes or lower lids, young women, can cause scar. dx. trx. prognosis
syringoma
none, risk of scarring, cosmetic: electro/curretage/shave
once they show up they are stable
2-3 mm dome shaped papules, usually around the eyes, on the cheeks, in a photodistribution. They are more common in black or hispanic women. dx. trx.
dermatosis papulosis nigra
no trx, but can freeze (HYPOPIGMENTATION), small: electrocautery & curette, large: remove,
treat one or two at at time to determine the response
seborrheic keratosis
seborrheic keratosis
what is the mc benign soft tissue tumor?
lipoma
treatment for skin tags?
acrochordon
large: anesthesia w/ excision
small: scissor, electrodessication, cryosurgery
SEND TO PATH
sebaceous hyperplasia
small tumors of enlarged sebaceous glands. Dome shaped w/ central puncta. in sund damaged oily skin on face. may have telangectasia that occurs on w/in valleys between small yellow lobules. dx. trx. extra thoughts
sebaceous hyperplasia
can scar because it goes into dermis
no treatment, but can shave, if real bad isotretinoin
d/o BCC because of the telangectasia
dif between keloid and hypertrophic scar?
keloid extends beyond borders of wound site, starts later, stable and doesnt subside
hypertrophic scar confined to wound site, starts early and in time usually regresses
syringoma
stuck on, greasy appearance, sun damaged, sebaceous areas (face, back, chest, groin). dx. treatment. prognosis
seborrheic keratosis
no treatment, but maybe liquid N2, curettage
leser-trelat sign: sudden appearnace of multiple seborrheic keratosis could indicate internal malignancy
what 3 benign tumors are a result of hyperproliferation of keratinocytes?
seborrheic keratosis
dermatosis papulosis nigra
stucco keratosis
what is the MC benign cutaneous neoplasm?
seborrheic keratosis
neurofibroma
treatment for keloid or HS?
intralesional steroid
can combo w/ surgery,
intralesional 5f/u
avoid trauma to skin/ reocurs if treatment is stopped
distincitve cental hyperkaratotic core, dome shaped red papule, MC on limbs and sun exposed surfaces (EARS, hands, arms). rapid expanision then stops in 6 weeks. maybe cauesed by sun damage or HPV. Old peeps (64). dx. trx. what does it look exactly like?
keratoacanthoma
excision then send to path R/O SCC
recurrent intralesional 5f/u or methotrexate
SCC
lipoma
“barnacles” caused by vascular deficiency, common in old white peeps w/ peripheral edema. stuck on appearance, located on ankles, feet, forearms, hands. dx. trx. prg
stucco keratosis
no treatment
poor circ so secondary infection, people pick them off on accident
what benign skin tumors recur?
seborrheic keratosis
stucco keratosis
sebaceous hyperplasia
hypertrophic scar/keloid
keratoacanthoma
pinkish-white, firm, waxy, nevus pedunculated, button hole sign, axilary freckling, cafe-au-lait spots. dx. trx. prognosis
neurofibroma
to treatment
axillary freckling, cafe au lait, >=2 refer to neuro for von recklinhausen, nf1
