small flat spot, up to 1.0 cm

ex: freckle, or petechia

circumsized, fat, non palpable changes in skin color

(2 examples)

macule

patch

palpable elevated solid masses

(4)

1. Papule

2. Plaque

3. Nodule

4. Wheal

(palpable elevated solid mass)

Up to 1.0 cm

example: an elevaed nevus

(palpable elevated solid mass)

elevated superficial lesion 1.0 cm or larger, ofeten formed by coalescence of papules

(palpable elevated solid masses)

marble like lesion; larger than 0.5 cm; often deeper and firmer than a papule. 

(palpable elevated solid masses)

a somewhat irregular, relativley transient, superficial area of localized skin edema. 

For example: hives, mosquito bites

wheal

1.vesicle

2. bulla

3. a pustule

(superficial elevation formed by free fluid)

Up to 1.0 cm; filled with serious fluid. 

Example: herpes simplex

(superficial elevation of skin formed by free fluid in cavity within skin layers)

1.0 cm or larger; filled with serous fluid.

example: second degress burn

(superficial elevation in the skin formed by free fluids in a cavity within skin layer)

filled with pus.

example: acne, impetigo. 

*circumscribed, flat, non palpable, changes in skin color

*palpable elevated solid masses

*circumscribed, superficial, elevations of the skin formed by free fluid in a cavity within the skin layers 

are all examples of:

*loss of skin surface

*material on the skin surface

are all examples of:

loss of the superficial epidermis, surface is moist but does not bleed

example: most area after rupture ofa vesicle, as in chicken pox.

A deeper loss of epidermis and dermia. May bleed and scar. 

Examples: stasis, ulcer of venous insufficiency, syphilitic chancre.

what is a linear crack in the skin?

ex: athletes foot

fissure (secondary lesion)

ANAL FISSURE!!! YES!!!

what is dry residue of serum, puss, or blood?

example: impetigo. 

what is a thin flake of exfolicated epidermis?

ex: dandruff, dry skin, psoriasis.

thickening and roughening of the skin with increased visibility of thenormal skin forrows. 

example: actopic dermatitis. 

Thinning of the skin with loss of the normal skin furrows; the skin looks shinnier and more translucent than normal.

example: arterial insufficiency. 

An abrasion or scratchmark. It maybe linear, or rounded, as in a scratched insect bite. 

Replacement of destroyed tissue by fiberous tissue. 

Maybe thick and pink which means hypertrophic, or thin and white (atrophic), but does not extend beyond the injured area. 

A persion with this condition has intense itching. skin lesions include small papules,pustules, lichenified ares, and excoriations. 

With a magnifying lens, look for the burow ofthe mite that caused it. 

Burrow of scabies

(commonly found in the finger webs and along the sides of fingers. it looks like a short 5-15mm linear or curved, gray line. May end in a tiny vesicle). 

the common mole. appears flat to slightley elevated, round, and evenly pigmented. 

however, some nevi look quite different. as in the pigmented nevi of melanoma.
