A

varoucous, raised, possible a papule, maybe a plaque or nodule

seborrheic keratosis

7

A

seborrheic keratosis

8
Q
A

seborrheic keratosis

9
Q

primary morphology

A

pedunculated papule. acrochordon

10
Q
A

erythematous and yellow umbilicated papules on places with evident pores. sebacious hyperplasia

11
Q

primary morphology

A

macule. solar lentigo

12
Q
A

seborrhaic keratosis

13
Q
A

actinic keratoses. papule, maybe a plaque

14
Q
A

actinic keratosis

15
Q

$

A

actinic keratosis

16
Q
A

actinic keratosis–erythematous papules/macules with scale on sun- exposed sites

17
Q

treatment for actinic keratosis

A

cryotherapy, maybe surgery, field therapy with fluorouracil

18
Q
A

squamous cell carcinoma

19
Q
A

squamous cell carcinoma

20
Q
A

squamous cell carcinoma

21
Q
A

squamous cell carcioma

22
Q
A

Squamous cell carcinoma – erythematous crusted papules, plaques, nodules

23
Q
A

basal cell carcioma– erythematous, umbilicated (sometimes), papule. doesn’t spread as fast as SCC

24
Q
A

BCC- papule, telangiectasia

25
Q
A

BCC- arborization/telangiectasia, erythematous papule

26
Q
A

BCC- arborization/telangiectasia, erythematous papule

27
Q
A

arborization/telangiectasia, erythematous papule

“pearly” papules, with ROLLED BORDER

28
Q

T/F SCC is usually due to sun in dark skin

A

false. SCC in dark skin is realted to chronic irritation or injury and not usually UVR

29
Q

SCC can be a result of which other dermatologic issue?

A

actinic keratosis

30
Q
A
31
Q
A

raised, hyperpigmented– BENIGN NEVIS

Benign nevi- macules, papules; brown, black, tan
• Symmetric • Uniform • Regular border and color • Looks like the others (no ugly duckling) • Stable in size and shape • Dome shaped/pedunculated- usually a feature of benign nevi

32
Q
A

Benign nevi- macules, papules; brown, black, tan
• Symmetric • Uniform • Regular border and color • Looks like the others (no ugly duckling) • Stable in size and shape • Dome shaped/pedunculated- usually a feature of benign nevi

33
Q
A

benign nevis

Benign nevi- macules, papules; brown, black, tan
• Symmetric • Uniform • Regular border and color • Looks like the others (no ugly duckling) • Stable in size and shape • Dome shaped/pedunculated- usually a feature of benign nevi

34
Q
A

Benign nevi- macules, papules; brown, black, tan
• Symmetric • Uniform • Regular border and color • Looks like the others (no ugly duckling) • Stable in size and shape • Dome shaped/pedunculated- usually a feature of benign nevi

35
Q
A

raised, hair, larger macule

congenital melanocytic nevus

•in Large (giant) >20cm, Incr risk of melanoma up to 5% , risk incr with satellite lesions and larger size of CMN

36
Q
A

congenital melanocytic nevus

37
Q
A

melanoma– look at irregular color, shape, (ABCDE)

38
Q
A

Fibrous papule of the nose (angiofibroma)- papule

39
Q

subtypes of primary invasive melanoma

A
40
Q

____ ____ is a type of melanoma in situ that arises within chronically sun damaged skin and can remain in situ for years

A

lentigo maligna

41
Q

gene and environment susceptibility for melanoma

A
42
Q
A

melanoma

43
Q
A

melanoma (most likely acral lentiginous melanoma)

44
Q
A

melanoma

45
Q

5 premises for Diagnosis = Early detection

A
  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
46
Q

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

A

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)

47
Q
A
48
Q

WHich type of UV are we most affected by?

A

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

49
Q

stats for tanning beds and cancer

A

• 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
