Pattern
Intertriginous

Pattern
Truncal

Comedones
Dilated and plugged hair follicles
Shape
Arcuate
Arc-shaped
Erosion
Loss of a portion of the epidermis, usually moist, won’t scar
Lichenification
Thickening of the epidermis and some changes in the dermis may be due to continual rubbing of the skin
Telangiectasia
Persistent dilations of small capillaries. May or may not be blanchable
Pattern
Scattered
Irregularly distributed
Pattern

> 0.5 cm
Scale
Flakes of skin
Excoriations
Surface excavations that result from scratching
Purpura
Reddish-purple lesion that is non-blanchable, indicating blood having left the vessels and moving through other tissues
Scar

Any change in skin color that is not palpable (not raised or depressed)
Horn
Conical Mass

Pinpoint purpura
Wheals
Pink papules or plaques that change or disappear within hours.
Angioma
Benign tumor with blood vessels; some types blanch, others don’t

Annular
Ring-shaped; the edge differs from the center
Plaque
A plateau-like elevation, usually well defined

Cavity is filled with purulent exudate
Sclerosis
