What is integument?

Integument is the natural covering of an organism (or an organ), such as its skin or shell. It derives from integumentum, which means "a covering" in Latin (Wiki)

2

What characteristics need to be included in the description of skin lesion/condition?

  • type of lesion (primary or secondary + name)
  • colour, shape, texture
  • configuration (arrangement of lesion(s): linear, annular, grouped,...)
  • distribution/location

3

What is a primary lesion

primary lesion - lesion that appears as a direct result of the pathologic process

4

What is a macule?

small spot, not palpable, <1 cm

5

What is a patch?

large spot, not palpable, > 1 cm patch may be de novo or through coalescence of macules

6

What is a papule?

small bump; superficial, elevated, < 1cm

7

What is plaque?

large bump; superficial, elevated, > 1 cm a plaque arises de novo or as the result of coalescence of papules

8

What is a nodule?

significant deep component, small bump, <1 cm

9

What is a tumor?

significant deep component, large bump > 1 cm

(dermalogic use of "tumor" is different)

10

What is a vesicle?

small bubble, fluid-filled, usually superficial, <0.5 cm

11

What is bulla?

large bubble, fluid filled, can be superficial or deep, > 0.5 cm vesicobullous lesions are almost always clinically important

12

What is pustule?

pus-containing bubble;

often categorized according to whether or not they are related to hair follicles

follicular - generally indicative of local infection

non-follicular - may indicate systemic infection

13

What are some types of follicular pustules?

folliculitis: superficial, generally multiple

furuncle: deeper form of folliculitis

carbuncle ("boil"): deeper, multiple follicles coalescing

14

What is a cyst?

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

15

small spot, not palpable, <1 cm

macule

16

small bump; superficial, elevated, < 1cm

papule

17

significant deep component, small bump <1 cm

nodule

18

small bubble, fluid-filled, usually superficial, <0.5 cm

19

pus-containing bubble; often categorized according to whether or not they are related to hair follicles follicular - generally indicative of local infection non-follicular - may indicate systemic infection

20

cyst

21

large bubble, fluid filled, can be superficial or deep, > 0.5 cm vesicobullous lesions are almost always clinically important

bulla

22

significant deep component, large bump > 1 cm ( careful re: non-deem use in describing neoplasms)

tumour

23

large bump; superficial, elevated, > 1 cm a plaque arises de novo or as the result of coalescence of papules

plaque

24

large spot, not palpable, > 1 cm patch may be de novo or through coalescence of macules

patch

25

what is a lesion?

lesion is any abnormality in the tissue (in layman's terms, " damage"), usually caused by disease or trauma (Wiki)

26

What are wheals or hives?

short-lived (<24 hrs) edematous, well circumscribed papules or plaques seen in urticaria (pale red, raised, itchy)

primary lesions

 

27

What is a burrow?

a small threadlike curvilinear papule that is virtually pathognomonic of scabies (contagious skin infection caused by mite Sarcoptes scabiei, which burrows under the host's skin, which in most people causes an intense itching sensation caused by an allergic response; often transmitted skin-skin)

28

What is comedone?

can be open or closed​

29

What is atrophy?

thinning of epidermal and/or dermal tissue

30

What is keloid? How is it different from hypertrophic scar?

 A keloid overgrows the original wound boundaries and is chronic in nature

Hypertrophic scars do not overgrow the original wound boundaries
