1

Icthyosis vulgaris

chronic, inherited skin disorder characterised by diffuse derma scaling --> skin appears dry and rough with horny plates resembling fish or reptile scales
treatment: emollietes, keratolytics, topical retinoids

2

clobetasol

high potency topical glucocorticoids

3

MCC of erythema multiforme

HSV

4

acne vulgaris - types

1. comedonal acne: closed or open comedones on forehead, nose + chin
2. inflammatory acne: pustules
3. nodular (cystic) acne: large nodules that can appear cystic

5

comedonal acne - treatment

topical retinoids, salicylic, azelaic or glycolic acid

6

infl acne - treatment

mild: topical retinoids + benzoyl peroxide
moderate: add topical antibiotics: erythrom or clindamycin
severeL add oral antibiotics

7

nodular cystic acne

moderate: topical retinoid + benzoyl peroxide + topical antibiotcs
severe: add oral antibiotics
unresponsive: oral isotretinoin

8

Mohs surgery

thin layers are reemoved and inspected microscopically to ensure clear margins --> used for high risk lesions in delicate or cosmeitically sensitive areas

9

lupus vs rocasea facial rash

similar distribution --> lupus is darker, spares nasolabial, not affected by alcohol

10

rosacea - treatment

1. avoidance of triggers
2. sun protection
3. gentle cleansers + emollients
4. topical metronidazole for papulopustular type
5. laser or topical brimonidine (vasocontrictive a2 agnostis)

11

venous stasis ulcers - location

pretebial area or above medial malleolus

12

arterial ulcers - location

most distal areas (tips)

13

pressure decubitus ulcers

common over bony prominences (sacrum, ischial , heel, 1st or 5th metatarsal

14

Piebaldism

AD disorder characterized by patchy absence of melanocytes (children)

15

RF for widespread molluscum contagiosum

impaired cellular immunity (eg. HIV)

16

hidradenitis suppurativa is a

chronic, relapsing condition characterized by inflammatory occlusion of folliculopilosebaceous units
--> interginous skin areas + presennts as painful nodules that can progress to abcesses that open to the skin surface
complications: sins tracts, comedones, scarring

17

senile purpura

ecchymoses in elderly patietns in areas exposed to repeated minor trauma (extensor surface) --> due to age-related loss of elastic fibers in perivascular connective tissue

18

actinic keratosis

scaly papules or plaques on the scalp, face, lateral neck, dorsal surface of the han
chronic sun exposure in the major RF --> can progress to SCC

19

erysipelas vs cellulitis on manifestation

- erysipelas: superficial, raised , sharply demarcated edges, rapid onset, fever early in course
- cellulitis; deep, flat edges with poor demarcation, indolent, fever later

20

dermatofibromas

nontender, firm, hyperpigmmented nodules that are usually smaller than 1 cm in diameter --> lower extremities --> contain fibrous component that causes central area to dimple when pinched

21

mutlipe skin tag - seen ini

1. insulin resistance
2. pregnancy
3. perianal Crohn

22

lipomas vs epidermal cysts

lipomas are soft and irregular, and do not typically regress and recur
also cyst can produce cheesy white discharge

23

Telogen effluvium - clinical findings

1. acute, diffuse, noninflammatory hair loss
2. scalp + hair fibers appear normal
3. hair shafts easily pulled out (hair pull test)

24

telogen effluvium - triggers

severe illness, fever, surgery
pregancy, childbirth
emotional distress
endocrine disorders

25

telogen effuvium - management

adress underlying cause
reassurance
