be flat or raised border 2 Types 1.Ulcer 2.Erosion Depth described
as 1.Superficial: 3mm 2.Deep: 3mm Slide 34 Slide 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) Slide 36 Slide 37 Slide 38 2. Depressed
Lesion EROSION Shallow Does not extend through the epithelium to
underlying bone Slide 39 Wilkins p.153 Slide 40 3. FLAT LESIONS
Slide 41 Slide 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 Slide 43 Flat Lesion: Macule
Slide 44 Flat Lesion: Patch Slide 45 Slide 46 Review A tumor is one
cm or less in width. A nodule is greater than one cm in diameter.
