Lesion Descriptions (EIOE) Concorde Career College Preclinical Sciences DH101 Lisa Mayo, RDH, BSDH Virginia Carrillo, RDH, BSDH
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)
Metric conversions 1inch = 2.54cm 1cm = 10mm
Lesions: 3 Categories 1. Elevated 2. Depressed 3. Flat
1. ELEVATED LESIONS 1.) Blisterform 2.) Nonblisterform
BLISTERFORM Contains fluid Soft Translucent Types 1.Vesicle 2.Pustule 3.Bulla 1. Elevated Lesions
Blisterform Vesicle Small, less than1cm diameter Circumscribed lesion Thin surface covering May contain serum or mucin
1. Elevated Lesions Blisterform Pustule More or less then 5mm in diameter Contain pus Pus gives yellowish color
1. Elevated Lesions Blisterform Bulla Large, ≥1cm Filled with fluid: mucin or serum, may contain blood Color depends on the fluid content
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
SESSILE OR PEDUNCULATED?
Papules Small, pinhead less than 1cm in diameter Solid lesion May be pointed, rounded, flat-topped 1. Elevated Lesions Nonblisterform
Nodules Larger then papule Over 1cm in diameter 1. Elevated Lesions Nonblisterform
Tumor 2cm or greater width General swelling or enlargement This context does not refer to a neoplasm (benign or malignant) 1. Elevated Lesions Nonblisterform
Plaque Slightly raised lesion with a broad, flat top Larger than 1cm in diameter “Pasted-on” appearance 1. Elevated Lesions Nonblisterform
PlaquePapule
Wilkins p.152 Do not refer to Wilkins for descriptions, refer to my slides which come from Neild book
2. DEPRESSED LESIONS
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
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)
2. Depressed Lesion EROSION Shallow Does not extend through the epithelium to underlying bone
Wilkins p.153
3. FLAT LESIONS
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
Flat Lesion: Macule
Flat Lesion: Patch
