Pathologies of integumentary system Flashcards
Region in which tissue has suffered damage through injury or disease
lesion
Due to overstimulated sebaceous glands; small masses of hardened, discolored sebum that was exposed; a.k.a comedo; comedones
Blackheads
Large blister (fluid filled sac or lesion when fluid is trapped under a thick layer of skin)
Bulla
A.k.a contusion or hematoma
Bruise
Elevated circular mound; can be skin color or erythema and contents can be semisolid or partly fluid filled; ex. Acne Sebastian’s cyst
Cyst
Deep cut or tear in skin or skin & flesh
Laceration
Flat skin discoloration; usually no change in skin texture or thickness ex. Freckle, flat mole, some rashes such as with measles
Macule
Elevated, solid lesion
Papule
Elevated or depressed skin area, may be flat topped or rounded ex. Lesions or psoriasis
Plaque
Small blister or pimple on the skin containing pus ex. Whitehead, blackhead
Pustule
Mark left of skin where a wound, burn, or sore has not healed completely & fibrous connective tissue has developed;
Scar
Raised scar caused by excessive protein (collagen) in the skin that built during healing process
Keloid scar
Round sore on skin or mucous membrane with loss of epidermis and portions of dermis (may even be as deep as subcutaneous fat)
Ulcer
Bubble-like sac of fluid when water is trapped under the epidermis ex. Blister, some bug bites
Vesicle
Red, swollen mark left on flesh by a blow or pressure; also seen with hives
Wheal
Pale or white-topped pustule on the skin
Whitehead
Genetic mutation; congenital absence of melanin; white to light pink color
Albinism
Due to pigmentation or dilated capillaries present on the skin at birth; a.k.a birthmarks; ex. Port-wine stain and mole (can develop into a malignant melanoma)
Nevus
Common, noncontagious, autoimmune chronic skin disease; reddened skin covered by dry, silvery scales (called plaques); common on scalp, elbows, knees, back, & buttocks
Psoriasis
Autoimmune disorder of the connective tissue; inflammation & overproduction of collagen; usually appears in 30-50 years old
Scleroderma
Autoimmune (melanocytes slowly destroyed in ever-enlarging patches of skin); acquired condition of leukoderma that affects skin or hair; white, depigmented patches interspersed with normally pigmented skin
Vitiligo
Benign tumor composed of blood or lymphatic vessels; common in newborns & usually disappear during childhood
Angioma
Second leading cause of cancer death in women (1 in 8) mammograms, fine-needle biopsy; lumpectomy, mastectomy, radical mastectomy
Breast cancer
Caused by pressure & friction; cone-shaped areas on or between toes; thickening of stratum corneum & a central core of keratin (which distinguishes it from a callus)
Corns
Most common breast disorder (50% of women); breast cancer is more common with these women
Fibrocystic disease
Benign tumor formed of mature fat cells; a soft, moveable subcutaneous nodule; typically found on trunk, forearms, or neck
Lipoma
Formed by melanocytes; watch for changes, can develop into a malignant melanoma a.k.a. Nevus
Mole
Benign growths that appear in middle-aged and elderly; light brown or black flat areas that can be mistaken for moles or warts
Seborrheic keratosis
Small, soft, flesh-colored or pigmented benign growth; often on axillary or groin region
Skin tags
Subcutaneous tumor of sebaceous glands that contain sebum, keratin & hair follicle cells; small growth on scalp, neck or back; a.k.a. Sebaceous cyst or wen
Steatoma
Least malignant & most common (50%) of the skin cancers; tend to have a whitish border
Basal cell carcinoma
Begins as a pigmented lesion that develops into an ulcerated crater; may be invasive, but rarely metastasizes
Squamous cell carcinoma
Most serious & least common (2%) of the skin cancers that metastasizes quickly ABCDs for identifying possible melanomas - Asymmetry, border irregular, color change, diameter growth
Malignant melanoma
