Skin Path Flashcards
melanocytic nevus
normal mole - benign, small, well defined
atypical nevus
dysplastic nevus, large, irregular border/pigment
higher risk of melanoma
blue nevus
small, slightly elevated blue black, (dorsal hand), asians, benign if unchanging in years
freckles/lentigines
flat brown spots - darken and fade
lentignines - sun exposed areas in 40s/50s (dont fade)
- evaluate for cancer risk
Seborrheic keratoses
benign plaques, mc in elderly
appear stamped onto the skin
velvety or warty surface, brown or black
malignant melanoma
ABCD - prognosis on thickness
excision
sentinal node biopsy for staging
types of malignant melanoma
lentigo maligna melanoma - chronic sun exposed skin older patient
superficial spreading MM: 2/3 of all, sun exposed skin
nodular
acral=lentiginous melanoma - palms, soles, nails
occular melanoma
MM on mucus membranes
atropic dermatitis
pruritis,flexor surface lichenification, <5yo
rough red plaques with thick scale, lichenified
lichen simplex chronicus
chronic itching/scratching
dry, leathery, hypertrophic, lichenified plaques on neck/ankles/perinieum
give corticosteroids
psoriasis
common benign inflammatory skin disease at one site - koebner phenomenon worse with obesity red, sharply definied silvery scales pitting nails
pityriasis rosea
common mild acute inflammatory disease
females/young adults, spring/fall
oval fawn-colored plaques, 2 cm centers have crinkled paper appearance, lasts 6-8 weeks no scarring
seborrheic dermatitis
pruritis dry scales, or oily yellow crust
acute/chronic papulosquamous dermatitis
discoid and subacute lupus erythematosis
(chronic cutaneous forms of SLE)
DLE - atrophy, telangiectasisa, depigmentation
SCLE - erythematous non scarring red plaques
cutaneous T cell lymphoma(mycosis fungoides)
