|
|
|
Primary melanoma of the skin generally affects what demographic?
|
young and middle-aged
|
|
|
curability of melanoma is directly related to___?
|
size and depth of the lesion
|
|
|
examination for melanoma should include which areas?
|
the back above the waist, the legs, btwn the knees and ankles (women), scalp, toes and soles (dark skinned people), and skin around orifices
|
|
|
radial growth means? vertical growth means?
|
radial = growth 'out', preinvasive, intraepidermal ; vertical= growth into dermis, invasive
|
|
|
MOST AGGRESSIVE MELANOMA??
|
NODULAR MELANOMA!!!
|
|
|
most benign/longest radial growth phase melanoma?
|
lentigo maligna melanoma
|
|
|
most COMMON melanoma?
|
superficial spreading melanoma
|
|
|
precursors of cutaneous melanoma?
|
CONGENITAL nevomelanocytic nevus (giant or small), CLARK'S (dysplastic) melanocytic nevus, LENTIGO maligna
|
|
|
aquired, circumscribed, pigmented lesions of atypical melanocytes?
|
Clark Melanocytic Nevus
|
|
|
Clark MN seen in what demographic?
|
whites, almost never in asians (esp japanese) (equal in males and females, children and adults)
|
|
|
what size Congential Nevomelanocytic nevus has malignant potential?
|
any size! small or large (also equal among race and sex)
|
|
|
"wormy", soft lesions and "pebbly" skin surface appearance with reticular dermis infiltration
|
Congenital NN (remember: carcinomas palpate HARD, melanomas palpate SOFT)
|
|
|
when should CNN's be removed?
|
small = before 12 years old ; large = ASAP (may require skin graft, may perform on young child, 3-5)
|
|
|
Least common of the three prinicipal melanomas of white ppl (SPT I, II, III)?
|
lentigo maligna melanoma
|
|
|
What are the three prinicpal melanomas of white ppl?
|
Superficial spreading melanoma, Nodular melanoma, and lentigo maligna melanoma
|
|
|
melanoma occuring primarily in older people?
|
lentigo maligna -- median age = 65 y/o
|
|
|
before invading the dermis and therefore becoming LMM, how does LM present?
|
focal papular and nodular areas
|
|
|
What is the average period of growth for LM to LMM?
|
20 years
|
|
|
"striking variations in hues of brown and black, appears like a stain, network of black on brown background" describes ____?
|
lentigo maligna (LM)
|
|
|
LM presents with black 'stains' on a brown background-- what signals the change to LMM?
|
development of gray (focal regression) or blue areas (dermal pigment involvement) and/or papules or nodules of blue black or pink
|
|
|
what are the two major cancers that arise in melanocytes of white ppl?
|
superficial spreading melanoma, and nodular melanoma
|
|
|
SSM arises most frequently on which area of the body / how fast does it grow?
|
m/c on upper back; 1-2 yrs (faster than LMM [ 20 yrs] but still classified as slow growing)
|
|
|
SSM arises m/c in which demographic?
|
white-skinned, 30-50 y/o, females > males
|
|
|
What are the four major risk factors for SSM? (in order of importance)
|
1. presence of precursor lesions (Clark's, CMN)
2. Family history 3. SPT I or II 4. Excessive sun exposure, esp during preadolescence (esp in young, urban professionals, with intermittent, intense sun exposure ['weekenders'] ) |
|
|
"flattened papule, becoming a plaque, then nodules; dark brown or black with pink, gray, or blue-gray hues, asymmetrical isolated, single lesions" describes ______?
|
SSM
|
|
|
Which is kills more people-- melanomas or carcinomas? Which is more common?
|
Melanomas kill more people; carcinomas are more common (melanomas are slow growing and so easy to miss/ignore but are more malignant once developed)
|
|
|
What is the second m/c melanoma occuring in light-skinned ppls?
|
Nodular Melanoma (m/c of all is SSM)
|
|
|
which melanoma of those commonly affecting light-skinned ppl is the fastest growing?
|
Nodular melanoma! (4 mos - 2 yrs vs. 1-2 yrs (SSM) and 20 yrs (LMM) )
|
|
|
What feature, which is found in LMM and SSM, is absent in NM?
|
precursor lesion ("adjacent epidermal component")
|
|
|
In which demographic is NM (normally 2nd m/c melanoma) more frequent than SSM (normally mc)?
|
Japanese
|
|
|
Enlisted members must be informed the right to demand a trial by court martial instead of NJP if?
|
