adipocyte

Person with skin deficient in pigment
(melanin).

One of the large dermal exocrine glands located in the axilla and genital areas. It secretes sweat that, in action with bacteria, is responsible for human body odor.

Deepest region of the epidermis; it gives rise to all the epidermal cells.

Structural protein found in the skin and connective tissue.

Band of epidermis at the base and sides of the nail plate.

Middle layer of the skin.

Most numerous sweat-producing exocrine gland in the skin.

Outermost layer of the skin.

Layer of skin cells forming the outer and inner surfaces of the body.

Sac within which each hair grows.

The skin and its accessory structures such as hair and nails.

Hard protein material found in the epidermis, hair, and nails.

The half-moon-shaped, whitish area at the base of a nail.

Major skin pigment. It is formed by melanocytes in the epidermis.

Soft tissue surrounding the nail border.

Tiny opening on the surface of the skin.

Oil-secreting gland in the dermis that is associated with hair follicles.

Oily substance secreted by sebaceous glands.

Flat, scale-like cells composing the epidermis.

Arranged in layers.

A layer (of cells)

Outermost layer of the epidermis, which consists of flattened, keratinized cells.

Innermost layer of the skin, containing fat tissue.

Solid, round or oval elevated lesion 1 cm or more in diameter.

Small (less than 1 cm in diameter), solid elevation of the skin.

Growth extending from the surface of mucous membrane.

Papule containing pus.

Open sore on the skin or mucous membranes (deeper than an erosion).

decubitus ulcers

Small collection (papule) of clear fluid (serum); blister.

Smooth, edematous (swollen) papule or plaque that is redder or paler than the surrounding skin.

Absence of hair from areas where it normally grows.

Bluish-purplish mark (bruise) on the skin.

Small, pinpoint hemorrhage.

itching

Accute allergic reaction in which red, round wheals develop on the skin.

Chronic popular and pustular eruption of the skin with increased production of sebum.

vulgaris

Injury to tissues caused by heat contact.

Diffuse, acute infection of the skin marked by local heat, redness, pain, and swelling.

Inflammatory skin disease with erythematous, papulovesicular lesions.

Rash (exanthema) of the skin due to a viral infection.

Death of tissue associated with loss of blood supply.

Bacterial inflammatory skin disease characterized by vesicles, pustules, and crusted-over lesions.

Chronic, recurrent dermatosis marked by itchy, scaly, red plaques covered by silvery gray scales.

Contagious, parasitic infection of the skin with intense pruritus.

Chronic progressive disease of the skin and internal organs with hardening and shrinking of connective tissue.

Chronic autoimmune inflammatory disease of collagen in skin, joints, and internal organs.

Infection of the skin caused by a fungus.

Photosensitive, scaling, plaque-like, superficial eruption of the skin confined to the face, scalp, ears, chest, arms, and back, which heals with scarring.

tinea pedis

Loss of pigment (depigmnentation) in areas of the skin (milk-white patches).

Increased growth of cells in the keratin layer of the epidermis caused by pressure or friction.

Hypertrophied, thickened scar developing after trauma or surgical incision.

Normal scar left by a healed wound.

Thickened and rough lesion of the epidermis; associated with aging or skin damage.

White, thickened patches on mucous membrane tissue of the tongue or cheek.

Pigmented lesion of the skin.

Samples of skin are examined for presence of microorganisms.

Fluid that accumulates.

pus-filled

Scrapings from the skin lesions, hair specimens, or nail clippings are sent to a laboratory for culture and microscopic examination.

Use of subfreezing temperature via liquid nitrogen application to destroy tissue.

Use of a sharp dermal curette to scrape away a skin lesion.

Tissue is destroyed by burning with an electric spark.

Thin layers of malignant tissue are removed, and each is examined under a microscope to check for adequate extent of the resection.

Suspected malignant skin lesions are removed and examined microscopically by a pathologist.

Substances are injected intradermally or applied to the skin, and results are observed.
