| Circumscribed flat, non palpable changes in skin color. Small flat spot, up to 1.0 CM.
Example: freckle, petechia | Maculae: Woods
Macule:Bates |
| Circumscribed, flat non palpable changes in skin color. Flat spot, 1.0CM or larger | Patch |
| Circumscribed superficial elevation of skin formed by free fluid in a cavity within the skin layers, up to 1.0 cm; filled with serous fluid. Example: herpes simplex | Vesicle |
| Circumscribed superficial elevations of the skin formed by free fluid in a cavity, within the skin layer, 1.0CM or larger.
Example second-degree burn | Bulla |
| Circumscribed superficial elevation filled with pus.
Example: acne , impetigo | Pustule |
| A flake of exfoliated epidermis.
example: dandruff, dry skin, psoriasis | scale |
| Linear crack in the skin.
Example: athlete's foot | Fissure |
| Palpable elevated solid mass up to 1.0 cm, example elevated Nevis | Papule |
| Elevated superficial lesion, palpable ,1.0 cm or larger . Often for my coalescence of papules | Plaque |
| Marblel ike lesion larger than 0.5 cm. Often deeper and firmer than papule. | Nodule |
| Palpable, elevated solid mass, somewhat irregular relative to the transient superficial area of localized skin edema.
Examples: insect bite, hives | Weal |
| Loss of superficial epidermis; surface is moist but does not bleed.
Example: ruptured chickenpox | Erosion |
| Dried residue of serum, plus, or blood. Example impetigo | Crust |
| Deep loss of epidermis or dermis; may bleed and scar, examples: Stasis ulcer on venous insufficiency, syphilitic chancre | Ulcer |
| Thickening and roughing of the skin that with increased visibility of the normal skin furrows example: atopic dermatitis | lichenification |
| Thinning of the skin with loss of the normal skin furrows, the skin looks shinier and more translucent than normal.
Example arterial insufficiency | Atrophy |
| And abrasion or scratch mark, it may be linear, or rounded as in a scratched insect bite. | Excoriation |
| Replacement of destroyed tissue by fibrous tissue. May be thick and pink:hypertrophic. May be thin and white a hypotrophic but does not extend beyond the injured area. | Scar |
