grouped (clustered) as irregular rings
Polycyclic
Target lesion
grouped (clustered) as round rings
Annular
Serpinguinous lesion
circumscribed deposits of blood or blood pigments greater than 0.5cm. Do not blanch with pressure (diascopy)
Purpura
Petechiae
circumscribed deposits of blood or blood pigments less than 0.5cm but usually smaller, 1-2mm macules. Petechiae do not blanch with pressure (diascopy).
areas of thickened epidermis. The major sign of the thickening is increased prominence of the skin lines, although scaling and low grade inflammation are usually seen as well.
Lichenification
linear or curvilinear papule that house parasites such as the scabetic mite
Burrow
dilations of superficial vessels. Often linear or branch-like.
Telangiectasia
small, superficial keratin cysts.
Milia
A depression in the skin resulting from thinning of the epidermis, dermis, or subcutaneous fat.
Atrophy
A depression in the skin resulting from thinning of the epidermis, dermis, or subcutaneous fat.
Atrophy
linear losses of epidermis and dermis which have sharply defined, abrupt walls; a slit.
Fissure
loss of epidermis plus variable degrees of the dermis. Variable in depth, size, and shape. Heal with scarring.
Ulcer
collections of dried serum and cellular debris – “scab”.
Crust
circumscribed collection of free clear, fluid more than 0.5cm. in diameter
Bulla
circumscribed collection of free clear, fluid more than 0.5cm. in diameter
Bulla
circumscribed collection of free clear, fluid up to 0.5cm cm. in size
Vesicle
circumscribed collections of leukocytes and free fluid which are variable in size
Pustule
circumscribed collections of leukocytes and free fluid which are variable in size
Pustule

Macule
circumscribed, flat discoloration of skin up to 0.5 cm in size.
Macule
circumscribed, elevated, superficial, solid lesion larger 0.5 cm in size
Plaque
circumscribed, elevated, superficial, solid lesion larger 0.5 cm in size
Plaque
a special type of papule or plaque which is the response of the skin to histamine release and is characterized by the classic three features (triple response of Lewis) of edema, erythema, and a flare. The edema fluid is bound, which contrasts this lesion with the vesicle and bulla. transitory or evanescent, seldom remaining in one location for more than 3 or 4 hours.
Wheal
a special type of papule or plaque which is the response of the skin to histamine release and is characterized by the classic three features (triple response of Lewis) of edema, erythema, and a flare. The edema fluid is bound, which contrasts this lesion with the vesicle and bulla. transitory or evanescent, seldom remaining in one location for more than 3 or 4 hours.
Wheal
circumscribed, palpable, solid, round, or ellipsoidal lesion. refers to a growth that is both elevated above the skin surface and has a deeper component as well. Generally this refers to lesions larger than 0.5 cm, and most nodules are greater than 1cm and up to 4-5cm.
Nodule
circumscribed, elevated, superficial, solid lesion larger 0.5 cm in size
Plaque
circumscribed, flat discoloration of skin larger than 0.5 cm in size
