1. Lesion Descriptions (EIOE) Concorde Career College Preclinical Sciences DH101 Lisa Mayo, RDH, BSDH Virginia Carrillo, RDH, BSDH

2. DOCUMENTATION Describing a Finding (see cheat sheet) 1.Location 2.History: How long been there? 3.Single, multiple, group, separate, coalescing 4.Size: in mm (use probe to measure) 5.Shape: round, square, etc.. 6.Color 7.Surface Texture: smooth, irregular, verrucous (wartlike), papillary, fissured, corrugated, crusted 8.Consistency: soft, spongy, resilient, indurated 9.Elevated, Depressed, Flat (next slides)

3. Metric conversions 1inch = 2.54cm 1cm = 10mm

4. Lesions: 3 Categories 1. Elevated 2. Depressed 3. Flat

5. 1. ELEVATED LESIONS 1.) Blisterform 2.) Nonblisterform

7. BLISTERFORM Contains fluid Soft Translucent Types 1.Vesicle 2.Pustule 3.Bulla 1. Elevated Lesions

8. Blisterform Vesicle Small, less than1cm diameter Circumscribed lesion Thin surface covering May contain serum or mucin

10. 1. Elevated Lesions Blisterform Pustule More or less then 5mm in diameter Contain pus Pus gives yellowish color

12. 1. Elevated Lesions Blisterform Bulla Large, ≥1cm Filled with fluid: mucin or serum, may contain blood Color depends on the fluid content

15. NONBLISTERFORM Do NOT contain fluid Characterized by their base attachment 1.Pedunculated: narrow stalk or pellicle 2.Sessile: wide base Types 1.Papules 2.Nodules 3.Tumors 4.Plaques Elevated Lesions

17. SESSILE OR PEDUNCULATED?

19. Papules Small, pinhead less than 1cm in diameter Solid lesion May be pointed, rounded, flat-topped 1. Elevated Lesions Nonblisterform

22. Nodules Larger then papule Over 1cm in diameter 1. Elevated Lesions Nonblisterform

24. Tumor 2cm or greater width General swelling or enlargement This context does not refer to a neoplasm (benign or malignant) 1. Elevated Lesions Nonblisterform

27. Plaque Slightly raised lesion with a broad, flat top Larger than 1cm in diameter “Pasted-on” appearance 1. Elevated Lesions Nonblisterform

29. PlaquePapule

31. Wilkins p.152 Do not refer to Wilkins for descriptions, refer to my slides which come from Neild book

32. 2. DEPRESSED LESIONS

33. Below the surface level of the skin or mucosa Outline may be regular or irregular May be flat or raised border 2 Types 1.Ulcer 2.Erosion Depth described as 1.Superficial: ≤3mm 2.Deep: ≥3mm

35. 2. Depressed Lesions ULCER Loss of continuity of the epithelium Center is gray to yellow Red border May result from the rupture of an elevated lesion (Ex: popping a zit)

38. 2. Depressed Lesion EROSION Shallow Does not extend through the epithelium to underlying bone

39. Wilkins p.153

40. 3. FLAT LESIONS

42. On same level as normal skin or oral mucosa May occur 1.Single 2.Multiple Macule Circumscribed area not elevated above the surrounding skin or mucosa May be id by its color which is different then surrounding tissues

43. Flat Lesion: Macule

44. Flat Lesion: Patch

46. Review A tumor is one cm or less in width. A nodule is greater than one cm in diameter. A) The first statement is true and the second statement is true B) The first statement is true and the second statement is false C) The first statement is false and the second statement is true D) The first statement is false and the second statement is false

47. Answer C) The first statement is false and the second statement is true is the correct answer.
