pustules, vesicles, bullae, and wheals.
Macules - CORRECT ANSWER - < 1 cm
-flat (not raised, elevated, or depressed)
Patch - CORRECT ANSWER - A large macule
> 1cm
Papules - CORRECT ANSWER - < 1cm
-Elevated solid lesions
-May become confluent and form plaques
-Color varies
-Charaterized as spike-topped, slope-shaped, dome-shaped, flat-topped, or umbilicated
-May be firm or soft and fleshy
Umbilicated papule - CORRECT ANSWER - Has indentation at center
Plaque - CORRECT ANSWER - > 1cm
A broad papule (or confluence of papules)
Usually elevated but may have centralized depression
Nodules - CORRECT ANSWER - > 1cm
-Circumscribed, elevated, solid lesion
,-Similar to papules but larger and may involve both epidermis and dermis (goes deeper than
papule does)
Tumors - CORRECT ANSWER - >2cm
-Similar to nodules but larger
-Soft or firm and are freely movable or fixed masses of different sizes and shapes (but usually
>2cm)
-May be elevated, subcutaneous, or pedunculated
Pedunculated - CORRECT ANSWER - -On a stalk
-Looks like a mushroom
Pustules - CORRECT ANSWER - (Acne)
-Circumscribed, superficial cavity of skin that contains purulent exudate (pus)
-Appear white, yellow, greenish-yellow
-Can develop around hair follicle
-May develop as a pustule or from a papule or vesicle
Vesicle - CORRECT ANSWER - -Circumscribed, elevated, superficial cavity containing
fluid
-May be pale or yellow (from pus) or red (from serum+blood)
-Localized or irregularly scattered or grouped (herpes zoster) or linear (allergic contact
dermatitis)
-Often break spontaneously or develop into bullae
Bullae - CORRECT ANSWER - >1cm
-Rounded or irregularly shaped blisters containing serous or seropurulent fluid
-Differ from vesicles only in size
, -May be located superficially in epidermis, so walls are flaccid and thin (can rupture
spontaneously or from slight injury)
Wheals - CORRECT ANSWER - "Hives"
-A rounded, pale red, edematous (puffy or swollen) plaque due to infiltration of the dermis with
fluid
-Are transient and disappear within 24-48hrs
Secondary lesions - CORRECT ANSWER - Scales, crusts, excoriations, erosions ulcers,
fissures, scars
Excoriations - CORRECT ANSWER - scratches
Erosions - CORRECT ANSWER - smaller ulcers
Scales - CORRECT ANSWER - -Excess dead epidermal cells produced by abnormal
keratinization and shedding
-Dry or greasy masses of keratin
-Vary in size
-Scaling implies a pathologic process occurring in the epidermis
Tinea Versicolor - CORRECT ANSWER - Fine scales
Pityriasis Rosea - CORRECT ANSWER - Medium scale
Psoriasis - CORRECT ANSWER - Large scale
