1

Define: macule

flat, non-palpable lesion <1cm

2

Define: papule

elevated, solid, palpable lesion <1cm in diameter

3

Define: patch

flat, non palpable lesion >1cm in diameter that arises de novo or through coalescence of macules

4

Define: Plaque

elevated, solid, palpable lesion >1cm that arises de novo or through coalescence of papules

5

Define: pustule

pus containing lesion, usually small but can coalesce
- not synonymous with infection!

6

Define: vesicle

liquid or fluid filled (not pus) lesion that is <1cm in diameter

7

Define: Bulla

liquid or fluid filled (not pus) lesion that is >1cm in diameter

8

Define: Nodule

solid, palpable lesion with significant depth. Usually >1cm and extend into the dermis and/or subcutis

9

Define: Cyst

sac containing fluid or semisolid material (cells or cell products)

usually in the dermis and sub-cutis

10

Define: erythema nodosum

tender, red nodules on the shins
- have a certain amount of depth

reaction pattern common when a patient is on certain drugs, has chronic disease, or cancer

11

Define: wheals/hives

transient (<24hours) well circumscribed papules and/or plaques seen in urticaria

Due to dermal edema and are usually pruritic

12

Define: telangiectasis

dilated superficial dermal vessel

13

Define: purpura

hemorrhage into the skin --> appears purple

non-blanchable

14

Define: petechiae

tiny pinpoint purpura present in the dermis

15

Define: ecchymosis

Larger scale hemorrhage into the skin (ie. bruising)

16

Define: comedone

dilated pore that contains keratinous debris
- can be open: "blackhead"
- can be closed "whiteheads"

17

Define: milium

Small superficial white coloured cyst containing keratin (usually <1-2 mm in size)

18

Define: burrow

small threadlike curvilinear papules that is pathognomonic of scabies.

Will be VERY itchy and can be found on the genitals and hands

19

Defnine: secondary lesion

lesions that appear as a results of alteration or evolution of a primary lesion (rubbing, scratching, trauma)

20

Define: scale

accumulation or excess shedding of stratum corneum

present in a broad scale of conditions due to epidermal inflammation

21

Define: crust

died exudate (blood. serum, pus) on the skin surface (ie. a scab)

22

Define: lichenification

an increase in skin lines/creases produced by chronic rubbing/scratching

23

Define: maceration

Softening and whitening of skin that is kept constantly wet

24

Define: hyperkeratosis

accumulation of keratin on the skin surface, usually adherent and compact

25

Define: fissure

a linear crack in the skin, often very painful

26

Define: excoriation

loss of skin due to scratching or picking

27

Define: erosion

superficial open wound
- loss of epidermis or mucosa only
- usually heals without scarring

28

Define: ulcer

deeper open wound with partial or complete loss of dermis or submucosa
- usually heals with scarring

29

Define: atrophy

thinning or diminution of epidermal, dermal, and/or subcutaneous tissue

Present with liner lesions along skin tension lines = striae

30

Define: hypertrophic scar

overgrowth of scar tissue along the wound boundaries
