Skin Lesions - Health Assessment

Question 1

a reddened localized collection of edema fluid; irregular in shape. size varies (examples are hives, mosquito bites.)

Answer 1

Wheal

Question 2

1 cm or larger, elevated, encapsulated, fluid-filled or semisolid mass arising from the subcutaneous tissue of dermis. (examples sebaceous and epidermoid cysts, chalazion of the eyelid)

Answer 2

Cyst

Question 3

A circumscribed, round or oval, thin translucent mass filled with serous fluid or blood. Vesicles are less than 0.5 cm (0.2in) Examples: large blister, second-degree burn, herpes simplex)

Answer 3

Vesicle, Bulla

Question 4

Vesicle or bulla filled with pus (example: acne vulgaris, impetigo)

Answer 4

Pustule

Question 5

Elevated, solid, hard mass that extends deeper into the dermis than a papule. Nodules have a circumscribed border and are 05 to 2 cm ( 0.2 in to 0.8 in) (examples: malignant melanoma. hermangioma)

Answer 5

Nodule, Tumor

Question 6

Plaques are larger than 1 cm (0.4 in) (Examples: psoriasis, rubeola)

Answer 6

Plaque

Question 7

Circumscribed, solid elevation of the skin. They are less than 1 cm (0.4 in) Examples: warts, acne, pimples, elevated moles

Answer 7

Papule

Question 8

Flat, unelevated change in color. They are 1 mm to 1 cm (0.04 to 0.4 in) in size and circumscribed. Examples: freckles, measles, petechiae, flat moles, Patches are larger than 1 cm and may be irregular in shape.

Answer 8

Macule, Patch

Question 9

A translucent, dry, paper-like, sometimes wrinkled skin surface resulting from thinning to wasting of the skin due to loss of collagen and elastin. (ex: striae, aged skin)

Answer 9

Atrophy

Question 10

Wearing away of the superficial epidermis causing a moist, shallow depression. Because erosions do not extend into the dermis, they heal without scarring. (ex: scratch marks, ruptured vesicles)

Answer 10

Erosion

Question 11

Rough, thickened, hardened area of epidermis resulting from chronic irritation such as scratching or rubbing (ex: chronic dermatitis)

Answer 11

Lichenifciation

Question 12

Shedding flakes of greasy, kerantinized skin tissue. Color may be white, gray, or silver. Texture may vary from fine to thick. (ex: dry skin, dandruff, psoriasis, and eczema)

Answer 12

Scales

Question 13

Dry blood, serum, or pus left on the skin surface when vesciles or pustules burst. Can be red-brown, orange, or yellow. Large crusts that adhere to the skin surface are called scabs (ex: eczema, impetigo, herpes, or scabs following abrasion)

Answer 13

Crust

Question 14

Deep, irregularly shaped area of skin loss extending into the dermis or subcutaneous tissue. May bleed. May leave scar.

Answer 14

Ulcer

ex; pressure ulcers, stasis ulcers, chancres

Question 15

Linear crack with sharp edges, extending into the dermis. (ex: cracks at the corners of the mouth or in the hands, athlete’s foot)

Answer 15

Fissure

Question 16

flat, irregular area of connective tissue left after a lesion or wound has healed. New ones may be red or purple; older ones may be silvery or white. (ex: healed surgical wound, or injury, healed acne)

Answer 16

Scar

Question 17

elevated, irregular, darkened area of excess scar tissue caused by excessive collagen formation during healing. Extends beyond the site of the original injury. Higher incidence in people of African descent

Answer 17

Keloid (ex: keloid from ear piercing or surgery)

Question 18

Linear erosion

Answer 18

Excoriation (ex: scratches, some chemical burns)
