adverse microclimate and shear in the skin over the pelvis and shear in the heel
Stage 3 (Full-thicknessskinloss)
adipose is visible in the ulcer
granulation tissue and epibole (rolled wound edges) are often present
Stage 4 (Full-thicknessskin and tissueloss) : exposed or directly palpable fascia, muscle, tendon, ligament, cartilage or bone in the ulcer
Unstageable Pressure injury (ObscuredFull-ThicknessSkin and TissueLoss): issue loss in which the extent of tissue damage within the ulcer cannot be confirmed
MACULE AND PATCH
small, flat, nonpalpable skin color change
skin color may be brown, white, tan, purple, red
macules: <1cm, circumscribed border
patches: >1cm, irregular border
Freckles: flat, small macules of pigment that appear following sun exposure
Vitiligo depigmentation of the skin
Striae: sometimes called stretch marks
Seborrheic keratosis: a warty or crusty pigmented lesion
Scar: Skin mark left after healing of wound or lesion that represents replacement by connective tissue of the injured tissue
Mole (also called nevus): a flat or raised tan/brownish marking up to 6 mm wide
Cutaneous tag: raised papule with a depressed center
Cutaneoushorn
Cherry angiomas: small raised spots (1–5 mm wide) typically seen with aging.
Papule and plaque: Elevated, palpable, solid mass
Papules have a circumscribed border and are less than 0.5 cm
Plaques are greater than 0.5 cm and may be coalesced papules with a flat top
Picture below is psoriasisvulgaris, an example of plaque
Nodule and tumor: Elevated, solid, palpable mass that extends deeper into dermis than a papule
Nodules are 0.5 to 2 cm and circumscribed
Tumors are greater than 1 to 2 cm and donot always have sharp borders
Picture below is a keloid, a nodule
Vesicle and bulla: Circumscribed elevated, palpable mass containing serous fluid
Vesicles are less than 0.5 cm
Bullas are greater than 0.5 cm
Picture below is varicella (chickenpox), a vesicle
Wheal: Elevated mass with transient borders that are often irregular. Size and color vary. Caused by movement of serous fluid into the dermis
Picture below is a urticaria (hives)
Pustule: Pus-filled vesicle or bulla; Picture below is acne
Cyst: Encapsulated fluid-filled or semisolid mass that is located in the subcutaneous tissue or dermis; Picture below is a epidermoid cyst
Erosion: Loss of superficial epidermis that does not extend to the dermis; Picture below is an aphthous ulcer, aphthous stomatitis, or cankersore
Ulcer: Skin loss extending past epidermis, with necrotic tissue loss; picture below is a stasis dermatitis with venous stasis ulcer
Fissure: Linear crack in the skin that may extend to the dermis and may be painful; picture below is an interdigitaltineapedis with fissures and maceratio
Petechiae: Round red or purple macule that is 1 to 2 mm in size
Ecchymosis: Round or irregular macular lesion that is larger than petechial lesion
Hematoma: localized collection of blood creating an elevated ecchymosis
Spider angioma: Red arteriole lesion with a central body with radiating branches
Telangiectasis (Venousstar): Bluish or red lesion with varying shape (spider-like or linear) found on the legs and anterior chest
