Lesions Flashcards
breakdown of the outer layers of the skin (epidermis), usually because of a: Cut. Scrape, inflammation. Ex : rupture vesicle
Erosion
a mark left on the skin by a cut or burn that has healed
Scar
linear crack in the skin that may extend to the dermis and maybe painful ex chapped lips or hands and athletes foot.
Fissure
Skin Loss extending past epidermis with necrotic tissue loss. Bleeding and scarring are possible.
Ulcer
A dried exudate on the skin surface, either serum, blood or pus or a combination
- where the exudate from erosions and ulcers dries on the surface of the lesion.
Crust
a secondary skin lesion wherein the characteristic features of skin thickening, hyperpigmentation, and exaggerated skin lines are noted.
Lichenification
A dried exudate on the skin surface, either serum, blood or pus or a combination
- where the exudate from erosions and ulcers dries on the surface of the lesion.
Crust
a thick, dry flake of skin.
Scales
decrease in size or wasting away of a body part or tissue
Atrophy
HEMANGIOMA/INFANTILE HEMANGIOMA
Bright Red birthmark that shows up at birth or in the first or second week of life.
Stork bite, is a congenital capillary malformation present in newborns. It is a common type of birthmark in a newborn.
PORT-WINE STAIN (Nevus Flammeus).
, is a vascular lesion characterized by anomalous dilatation of end vasculature found just beneath the skin surface. The lesion contains a central, red spot and reddish extensions which radiate outward like a spider’s web. They may appear as multiple or solitary lesions.
Spider (star) angioma.
also known as spider naevus or spider telangiectasia,
a soft, squashable, blue or purple macule or papule, that is 0.2–1 cm in diameter. Although they may arise anywhere, most venous lakes are diagnosed on the lower lip (on the vermilion margin or mucosal surface), on an earlobe, or elsewhere on the face, neck, or upper trunk..
Venous lake
pinpoint, round spots that appear on the skin as a result of bleeding. The bleeding causes the petechiae to appear red, brown or purple. Petechiae (puh-TEE-kee-ee) commonly appear in clusters and may look like a rash. Usually flat to the touch, petechiae don’t lose color when you press on them.
Petechiae
purple-colored spots and patches that occur on the skin, and in mucus membranes, including the lining of the mouth
Purpura
A small bruise caused by blood leaking from broken blood vessels into the tissues of the skin or mucous membranes. Associated with trauma and bleeding tendencies.
Ecchymosis (bruise)
A localized collection of blood creating an elevated ecchymosis. It is associated with trauma. A hematoma is usually caused by a broken blood vessel that was damaged by surgery or an injury. It can occur anywhere in the body, including the brain.
Hematoma
Bluish or red lesion with varying shape (spider- like or linear) found on the legs and anterior chest. It does not blanch when pressure is applied. It is secondary to superficial dilation of venous vessels and capillaries and associated with venous pressure states.
Telangiectasis (Venous Star)
Papular and round red purple lesion found on the trunk or extremities. It may be blanch with pressure. It is a normal age related skin and usually not clinically significant
Cherry Angioma
ABCDE Criteria for Melanoma Assessment
A = Asymmetry
B = Border Irregularity
C = Color Variegation
D= Diameter greater than 6 mm
E = Evolving Changes*
A shiny, skin-colored bump that’s translucent, meaning you can see a bit through the surface.
Basal cell carcinoma
scaly red patches, open sores, rough, thickened or wart-like skin, or raised growths with a central depression.
Squamous cell carcinoma
first sign of melanoma is often a mole that changes size, shape or color. This melanoma shows color variations and an irregular border, both of which are melanoma warning signs. Melanomas can develop anywhere on your body.
Malignant melanoma
typically appear as painless purplish spots on the legs, feet or face. Lesions can also appear in the genital area, mouth or lymph nodes.
Kaposi’s sarcoma
