Flashcards in Derm Pics- Common Dermatoses I and II, Skin Cancers Deck (33)
1

Describe

= multiple scattered macuoles on the chest, red and pink in color 

2

Diagnose:

Vitiligo

-depigmented patch 

3

Describe: 

-multiple monomorphic flesh colored papules (elevated < 1 cm)

-umbilicated 

4

Diagnose and describe: 

Psoriasis

-large salmon colored plques w/ well defined border in a geographic distribution on the lower back and buttocks 

-lots of silvery scale (secondary lesion) 

5

Describe

Monomorphic pustules 

6

Describe:

Erosion with a bit of crust (stuff dried on top)

 

-erosion loss of some or all of the epidermis

-often from vesicles or bullae

7

Describe: 

Fissures on the edges/sides of the mouth

-different from erosions and ulcers

-fissures = linear or wedge shape tears in the epidermis 

8

Differentiate the clinical picture of atrophy of the
(a) epidermis
(b) dermis 

Atropy of the (a) epidermis = thin, wrinked skin 

-attached to answer card

ex: sun exposure, aging

 

Atrophy of the (b) dermis => clinically detectable depression in the skin (attached to question card) 

9

Describe the process:

= Lichenification 

-thickening of the skin (hyperkeratosis) due to chronic scratching or rubbing

-noted by the increased lines and skin markings

-associated w/ eczema 

10

Describe and diagnose: 

-small flat monomorphic papules, skin colored 

= Flat warts

11

Describe and diagnose 

= Warts

-periuncal (around the fingers) papules (raised

12

Describe:

-filiform (thread like) warts on nose 

13

Diagnose 

Plantars wart

14

Describe and diagnose:

Salmon colored plque w/ sharply defined borders and silvery white plaque = psoriasis 

15

Describe and diagnose: 

Small, salmon-pink droplets on skin 

= Guttate psoriasis

-typically on upper trunk or extremities, in young adults, classically after bacterial infection (ex: strep throat) 

16

Describe and diagnose: 

Salmon pink plaque with well defined borders in intertrigenous area (where two skin areas touch) 

= Inverse psoriasis = very red lesions in body folds 

17

What is the white arrow pointing to? 

(a) Diagnose

(b) Other nail findings of this disorder

White arrow pointing to a yellow oil spot 

(a) Psoriatic nails

(b) Other nail findings in psoriasis = pitting, onycholysis (loosening or separation of nail from the nail beds), subungal debris (crap under the nail)

18

Describe and diagnose: 

Hyperpigmented macules (small patches) scattered

= Tinea versicolor

-versicolor b/c color varies- can be either hyper or hypopigmneted compared to background skin  

19

Describe and diagnose: 

-yellow scale on erethematous border in nasolabial fold 

= Seborrheic dermatitis

20

Describe how these three factors play into the pathogenesis of acne

(a) Bacterial

(b) Hormonal

(c) Epidermial 

Acne:

(a) Propionibacterium acne releases lipase that hydrolyzes the sebum TGs into FFAs

(b) Hormonal: androgens increase sebaceous gland activity

(c) Epidermial: hyperkeratinization of the hair follicle lining clogs the pore 

-get proliferation of the bacteria, regression of the sebaceous lobule, and inflammation 

21

Describe and diagnose:

 

-warty brown papule, well demarcated, verrucous (wart-like), appears 'stuck on' 

= Seborrheic Keratosis 

22

Descirbe and diagnose: 

Many small oval erethematous macules w/ a collarette of scale (circulation lesion w/ circular rim of scale or peeling edge) in a Christmas tree distribution on the chest and upper extremities 

23

Describe and diagnose: 

Erethematous macules (flat < 1 cm) w/ honey colored crusts (crap dried on top) = impetigo 

24

Describe and diagnose:

-pearly papule with central crater and telangectasia = Basal cell carcinoma 

25

Describe and diagnose: 

= Sclerosing basal cell carcinoma 

-scar-like circular plaque with well defined borders

26

Describe and diagnose: 

Small regular firm vesicles (clear fluid) on an erethematous base = Herpes simplex

-multiple grouped round vesicles that eventually become pustules (neutrophils, pus filled) then dry over, heal in 5-10 days

-not contagious once dried over

27

Describe and diagnose: 

Erethematous, oozing papules in atecubital fosssa and on face

= Atopic dermatitis = Eczema 

-often secondary lichenification and excoriation 

28

Describe and diagnose: 

Erythematous papules (raised), edematous, NO scale, sharply defined red borders with pale centers (wheals) 

= Uticaria/hives

29

Diagnose: 

Contact dermatitis- primary irritant type 

30

Diagnose

Contact dermatitis- allergic type

ex: poison ivy 

31

Basal Cell Carcionma 

-central ulcer/crust

-pearly white border and telengectasis on classical BCCs

32

Hyperkeratosis of Squamous cell carcinoma (SCC)

33

Actinic Keratosis = precancerous skin lesions due to chronic sun exposure

-8% of AK transform into SCC
