Macule - ANS flat lesion, less than 1.5 cm in diameter
patch - ANS a flat, discolored area on the skin larger than 1 cm
raised lesions - ANS papules nodules, cysts, plaques, and wheals
papule - ANS raised lesion no larger than 0.5cm; up to 1 cm
nodule - ANS solid, relatively spherical, at least 0.5cm. Round all around, distinguishing
cyst - ANS spherical, filled with semi-solid material
punctum - ANS black stuff inside a cyst or raised lesion
wheal - ANS lesion resulting from swelling via escape of plasma fluid from the upper dermis
fluid filled cavities - ANS vesicles, bulla, pustules
@COPYRIGHT ALL RIGHTS RESERVED PAGE 1 OF 16
,vessicle - ANS fluid filled cavity less than 0.5cm; small blister
bulla - ANS fluid filled cavity measuring at least 0.5cm in diameter; bull is plural
pustule - ANS thin walled puss filled pimple
depressed lesions - ANS erosions, ulcers, atrophy
erosion - ANS defect of the skin resulting from the loss or breakdown of the dermis
ulcer - ANS defect of the skin resulting from the loss or breakdown of the dermis and at least
the upper portion of the dermis. Heals with scaring
atrophy - ANS loss of the normal thickness of the skin
surface changes - ANS scaling, crusting, purulent, excoriation, fissure, elasticity,
lichenification
scaling - ANS small, dry particles which arise from the outermost layer of the epidermis
crusting - ANS hardened deposits resulting from dried fluid
purulent - ANS formed from puss, or puss like
excoriation - ANS injury to the surface of the skin resulting from excessive tension or
decreased elasticity. Common on hands and feet
lichenification - ANS thickening of the skin with accentuation of the surface markings. Think
"leather"/ leathery changes to the skin

, Adjectives of color - ANS erythematous, violaceous, purpuric, hyper-pigmented,
hypopigmented
erythematous - ANS red
violaceous - ANS violet/purple hue; typically inflammatory diseases located at the dermal-
epidermal junction
purpuric - ANS Pertaining to bruising of the skin.
hyper pigmented - ANS darker than the surrounding skin
hypo pigmented - ANS Lighter than the surrounding area
Shapes/ configurations of lesions - ANS linear, nummular/discoid, morbilliform, polycyclic.
arcuate, reticular
linear - ANS line-like
annular - ANS ring-shaped, like in ringworm
nummular/discoid - ANS round or coin shaped
blaschoid - ANS "whirled"
morbilliform - ANS "measles like"; multiple erythematous macules and papules
polycyclic - ANS comprised of numerous rings. Ex. polycyclic urticarial papules and plaques
