Skin Lesions

Shapes of Lesions:
Solid appearance-no cental clearing

Shapes of Lesions:
Round w/central clearing (tinea corporis)

Shapes of lesions:
Pink macule with purple concentric ring (erythema multiforme)

Shapes of lesions:
Snakelike appearance

Patterns of lesions:
Single lesion-demarcated lesions that remain separate (insect bite)

Patterns of lesions:
Lesions that bunch together in little groups (herpes simplex, impetigo)

Patterns of lesions:
Annular (round w/central clearing) lesions that come in contact w/one another as they spread (tinea corporis)

Patterns of lesions:
Lesions that merge and run together over large areas (pityriasis rosea)

Patterns of lesions:
Lesions that form a line (poison ivy)

Patterns of Lesions:
Lesions following a nerve (herpes zoster)

Patterns of lesions:
Lesions that are scattered all over the body (herpes varicella)

Describe a Macule:
Give an example:

Describe a Papule/give examples:

Describe a patch/give examples:

This primary skin lesion is elevated, firm and rough w/a flat top surface >1cm

Elevated irregular-shaped area of cutaneous edema, variable diameter

This primary skin lesion is elevated, firm, circumscribed, deeper in dermis than a papule; 1 to-2 cm

Primary skin leasion elevated and solid. May or may not be clearly demarcated; deeper in dermis; >2cm

Primary skin lesion: elevated, circumscribed, superficial, not into dermis; filled w/serous fluid; >1cm

Primary skin lesion: Vesicle >1cm

Primary skin lesion: Elevated, superficial; similar to vesicle but filled w/purulent fluid

Primary skin lesion: Elevated, circumscribed,
encapsulated lesion; in dermis or subcutaneous layer; filled w/liquid or semisolid material

Secondary lesions:
Heaped-up keratinized cells, flaky skin

Secondary lesion:
Rough, thickened epidermis secondary to peristent rubbing, itching or skin irritation: often involves flexor surface of extremity

Secondary lesion:
Irregular shaped elevated, progressively enlarging scar; grown beyond boundaries of the wound

Secondary lesion:
Thin to thick fibrous tissue that replaces normal skin following an injury or laceration to the dermis

Secondary lesion:
Loss of the epidermis; linear hollowed-out crusted area

Secondary lesion:
linear crack or break from the epidermis to the dermis

Secondary lesion:
Dried drainage or blood; slightly elevated

Secondary lesion:
Loss of part of the epidermis, depresser, moist, glistening, follows rupture of a vesicle or bulla

Secondary lesion:
loss of dermis and epidermis; concave

Secondary lesion:
Thinning of the skin surface and loss of skin makings; skin appears translucent & paperlike

Pressure ulcer stages:
observable pressure-related alteration of intact skin: indicators may include changes in skin temp, tissue consistency, sensation. Persistent redness

Pressure Ulcer stages:
Partial-thickness skin loss involving epidermis, dermis or both. The ulcer is superficial and appears clinically as an abrasion, blister, or whallow crater.

Pressure Ulcer stages:
Full-thickness skin loss involving damage to or necrosis of subut tissue that may extend down to, but not through, underlying fascia. Manifests clinically as a deep crater w/or w/out undermining of adjacent tissue

Pressure Ulcer Stages:
Full-Thickness skin loss w/extensive destruction, tissue necrosis, or damage to muscle, bone, or supporting structures. Undermining and sinus tracts may also be associated.
