1. Burns and Other Skin Lesions

2. Classification

3. First Degree Burn: Epidermis only

5. First Degree Burn

7. Second Degree Burn

8. Second Degree Burn: Epidermis and upper layers of the dermis

9. Second Degree Burn

10. Second-Degree Burns

11. Third Degree Burn: Complete destruction of the epidermis & dermis

13. Estimating percentages

14. Regeneration

15. Regeneration/Scarring

16. Scar Occurs whenever wound/ulcer has occurred; reflects healing
Keloid: Abnl formation of CT; form w/ dermal tissue damage; initially are thick but may w/ time become white and atrophic

19. Skin graft donor site: about halfway through the initial healing stage

20. Papule
Firm, raised lesion (less than 1cm in diameter)

21. Papule

22. Plaque
Large, raised lesion (greater than 1 cm in diameter)

23. Plaque - Psoriasis

24. Vesicle Thin-walled blister filled w/ fluid, <1cm
Between Epi/Derm junction or within dermis
Clinically significant

25. Vesicle

26. Pustule
Elevated lesion filled w/ pus

27. Pustule

28. Crust Hardened deposits of serum and cellular debris
result when serum, blood, or purulent (pus) exudates dries on skin surface
“scab”

30. Wheal
Firm, raised area of irregular shape/light center

31. Wheal

32. Cyst
Nodule that contains fluid or semisolid material

33. Macule
Distinguished from surrounding skin by color

34. Macule

35. Abrasion
Epidermis removed, revealing dermis

36. Excoriation
Epidermis is missing, dermis is exposed
Linear “scratch”

37. Ulcer
Craterlike lesion caused by disintegration of the skin (epidermis and dermis)
Heals w/ scarring

38. Bed Sore Compression of skin between bony prominence and other surface
Cuts off circulation
 leads to necrosis of tissue
- Lack of blood supply prevents proper healing
promotes infection

39. Fissure
Linear crack or break from epidermis to dermis
