Question 33

Answer 33

benign nevis

Benign nevi- macules, papules; brown, black, tan

Question 34

Answer 34

Benign nevi- macules, papules; brown, black, tan

Answer 40

lentigo maligna

Question 41

gene and environment susceptibility for melanoma

Answer 41

Question 42

Answer 42

melanoma

Question 43

Answer 43

melanoma (most likely acral lentiginous melanoma)

Question 44

Answer 44

melanoma

Question 45

5 premises for Diagnosis = Early detection

Answer 45

1. story of change
2. abcds
3. ugly duckling sign- not like other moles
4. little red riding hood sign: erythema or inflmmation surrounding melnoma
5. garbe’s rule: if a patient is worried about a single skin lesion, do not ignore their suspicion and have low threshold for biopsy

Question 46

T/F screening for melanoma is recommended because early detection is key

Answer 46

false. routine skin screening is not recommended despite excellent evidence early detection of melanoma is best. instead we should be screening high risk groups–> all those with a history of pmhx or fmx of melanoma

those with personal hx of melanoma, fam hx of melanoma, personal hx NMSC,
immunosuppression, physical features assoc with incr risk (blond or red hair, >40 nevi, >2 clinically atypical nevi, freckling, other signs of UVR overexposure)

Question 48

WHich type of UV are we most affected by?

Answer 48

More than 95% of sun’s UVR that reaches earth’s surface is UVA (all UVC and much of UVB are absorbed by oxygen and ozone).

Doses of UV light that do not induce sunburn still have profound
effects on skin

Question 49

stats for tanning beds and cancer

Answer 49

• People who first use a tanning bed before age 35 increase their risk
for melanoma by 75 percent.

• Indoor tanners are also 2.5 times more likely to develop squamous
cell carcinoma and 1.5 times more likely to develop basal cell
carcinoma
