Flashcards in Skin Lesions Deck (23):
1

Most important risk factor for development of skin cancer

exposure to natural and artificial UV radiation

2

Other risk factors for skin cancer besides exposure

family history, prior history, fair skin, red/blonde hair, easily sunburnt, chronic exposure to toxic compounds such as creosote, arsenic, radium, and suppressed immune system

3

Types of melanoma (+1 not quite a melanoma)

superficial spreading melanoma,
lentigo maligna,
amelanotic melanoma,
acral lentiginous melanoma,
nodular melanoma
melanoma in situ

4

Which melanoma has no invasion and is localized to dermis

melanoma in situ...if diagnosed early, should be excised with 5mm borders

5

What is the most common type of melanoma, clinical features of raised borders and brown lesions with pinks, whites, grays, blues

superficial spreading melanoma

6

Which melanoma is most often found in elderly, but is less common than other types, very irregular borders

lentigo maligna

7

Which melanoma usually remains undiagnosed

amelanotic melanoma

8

Most common melanoma found in AAs and Asians

acral lentiginous melanoma

9

Which is the most aggressive melanoma and is usually invasive by time of diagnosis

nodular melanoma; mostly black

10

What criteria can you use to help find suspicious lesions?

ABCD criteria

11

ABCD criteria for suspicious lesions)

Asymmetry
Borders (irregular)
Color (different colors)
Diameter (>6mm)
Elevation (raised)
Evolving (enlarging, thickening, or bleeding)

12

What can also be done in office to evaluate skin lesions

dermoscopy

13

Which lesions should be excised immediately

Any preexisting nevus that has changed or any new pigmented lesions with ABCDE signs with 2-3mm margin around lesions

14

If you can't immediately excise for cosmetic reasons, what can you do to help figure out malignancy?

biopsy....then if positive, then excision

15

Malignant melanomas need an excision of at least...

5mm

16

Once a malignant lesion is identified, how often should a patient be checked

Annually for any new or changing skin lesions

17

Biggest indicator for prognosis of melanoma

thickness

1 = poorer prognoses, more likely to metastasize

18

Who is recommended for behavioral counseling regarding sun exposure and skin cancer prevention

between 10-24 who are fair skinned

19

What are other skin malignancies other than melanoma

Basal cell and squamous cell

20

Most common of all cancers

basal cell carcinoma

21

Typical features of basal cell carcinoma

pearly papules often with central ulceration or with multiple telangietctasias
presents with growing lesions sometimes bleeding/itching

22

Prognosis for basal cell and squamous cell

basal cell less likely to metastasize but potential to grow large and destructive...excise that shit nigga

squamous cell more likely to metastasize (but still not very likely)

23

Tan colored lesions on sun damaged skin with very irregular borders, more common in elderly

lentigo maligna
