Early Clinic Vocab Flashcards
Lesion
A general term to denote a pathologic or traumatic change in the tissue. It is not descriptive.
Macule
Focal area of color change not elevated or depressed in relation to its surroundings; flat
Papule
Solid, raised lesion less than 5mm in diameter
Nodule
Solid, raised lesion greater than 5mm in diameter
Erythema
Red in color; a common but non-specific sign of irritation, injury or inflammation caused by dilation of superficial blood vessels
Erythematous
Relating to or marked by erythema
Sessile
Base is the widest part of an elevated lesion
Pedunculated
Base of an elevated lesion is narrower than the widest part
Papillary
Exhibiting numerous surface projections
Verrucous
Exhibiting a rough, warty surface
Erosive
Superficial, partial or total loss of surface epithelium; may arise secondarily from rupture of bulla (blister)
Ulcerated
Loss of surface epithelium down to the connective tissue, often appears depressed
Fissure
Narrow, slit-like ulceration or groove
Plaque
Slightly elevated and generally flat
Petechia(e)
Flat, round, pinpoint area(s) of hemorrhage, usually 3mm or less
Purpura
Hemorrhage into the skin, larger than petechia, but less than 1cm
Ecchymosis
Flat area of hemorrhage larger than 1cm; bruise
Vesicle
Fluid-filled, elevated, superficial, 5mm or less in diameter
Bulla
Fluid-filled, elevated, superficial, greater than 5mm in diameter
Pustule
Superficial, circumscribed cavity filled with pus (purulent exudate)
Indurated
Hardened
Fluctuant
Wavelike on palpation due to liquid content
Copious
Present in large quantity
Dermatoglyphics
Lines forming a skin pattern
Crenated
Scalloped
Varicose
Abnormally swollen, distended or dilated
Scale
Flakes of retained surface keratin
Crust
Dried blood, serum or purulent exudate (pus) on the skin surface
Size
Use a periodontal probe or milimeter/centimeter ruler (yeah, idiotic)
Site
Specificity is key (ie. right buccal mucosa at the line of occlusion near the commissure)
Shape
Round, oval, irregular, linear, triangular, lacy, crenated, etc.
Surface
Raised, flat, fissured, smooth, ragged, cobblestone, plaque, petechiae, purpura, ecchymosis, elevated, depressed, ulcerated, crust, erosive, papillary, verrucous, pustule, vesicle, bulla, etc.
Symmetry
Can pertain to symmetry of the lesion itself or whether the findings are, or are not bilaterally symmetrical
Color
Use this as descriptor
Borders/Margin
Well-defined, blended, discrete, crisply defined, irregular, scalloped, etc.
Mode of attachment
Sessile, pedunculated, broad based, narrow based
Consistency
Firm, fluctuant, soft, indurated, hard, bony hard, rubbery, thick, viscous, watery, thin, etc.
Number
1, 2, 3, 7000, solitary, multiple, scattered
Distribution
Solitary, widespread
Size (on radiographic)
Can be measured in mm or cm, but may best be described by the anatomic position of the boundaries,
Position
Localized, generalized, unilateral, bilateral, mandible, maxilla, relation to the crown and/or root
Shape
Oval, round, scalloped, scooped, triangular, tear-drop, expansile
Border
Well-demarcated, corticated, well-defined, ill-defined, blended, radiopaque, radiolucent, thick, thin, radiolucent rim
Density and internal structure
Completely radiolucent, completely radiopaque, mixed radiolucent-radiopaque, septae, unilocular, multilocular
Effect(s) on adjacent structures
Expansion, resorption, displacement
