GLOSSARY
Acne: A chronic skin disorder due to inflammation of hair follicles and sebaceous glands (secretion glands in the skin).
Actinic Keratoses: Actinic keratoses are common premalignant skin tumors that appear as small, raised, flaky lesions usually found on heavily sun exposed skin in older people. They are mainly due to long-term exposure to the sun in susceptible persons and may progress to squamous cell carcinoma.
Cellulitis: Cellulitis is an acute inflammation of the connective tissue beneath the surface of the skin. It is more wide-spread than a localized infection as seen in an ulcer or abscess. It causes the skin tissues in the infected area to become red, hot, painful and swollen.
Dermatitis: A general term used to refer to eruptions or rashes on the skin.
Eczema: Swelling of the outer skin of unknown cause. In the early stage it may be itchy, red, have small blisters, and be swollen, and weeping. Later it becomes crusted, scaly, and thickened.
Intertrigo: Intertrigo is a yeast infection (candida albicans) of the skin found under skin folds. It is notorious for flaring in response to hot humid weather. Moisture builds under the skin fold and the yeast flourishes leading to symptoms such as redness, scaling and significant itching. The skin may develop some raw spots. Little red bumps and pustules may be present. Typically the involved skin is red in color.
Lichen planus: Lichen planus of the skin is characterized by reddish-purple, flat-topped bumps that may be very itchy. They can be anywhere on the body, but seem to favor the inside of the wrists and ankles. The disease can also occur on the lower back, neck, legs, genitals, and in rare cases, the scalp and nails. Thick patches may occur, especially on the shins. Blisters are rare.
Lymph Nodes: Small, bean-shaped nodes at various points throughout the body that function to filter the lymph fluid and attempt to destroy the microorganisms and abnormal cells which collect there. The most common locations are the neck (both sides and front), armpit and groin, but also under the jaw and behind the ears. Swollen or painful lymph nodes generally result from localized or systemic infection, abscess formation, or malignancy. Other causes of enlarged lymph nodes are extremely rare. Physical examination for lymph nodes includes pressing on them to check for size, texture, warmth, tenderness and mobility. Most lymph nodes can not be felt until they become swollen, and then will only be tender when pressed or massaged. A lymph node that is painful even without touching indicates greater swelling. Lymph nodes can usually be distinguished from other growths because they generally feel small, smooth, round or oval-shaped and somewhat mobile when attempts are made to push them sideways. Because less fat covers the lymph nodes in children, they are easier to feel, even when they are not busy filtering germs or making antibodies. Children’s nodes enlarge faster, get bigger in response to an infection and stay swollen longer than an adult's.
MRSA: (Methicillin-Resistant Staphylococcus Aureus)
Psoriasis: An inherited skin disorder in which there are red patches with thick, dry silvery scales. It is caused by the body making too-many skin cells. Sores may be anywhere on the body but are more common on the arms, scalp, ears, and the pubic area. A swelling of small joints may go along with the skin disease.
Sebaceous Hyperplasia: A skin condition in which a person develops small, yellowish growths, usually on the face.
Seborrheic Dermatitis: Seborrheic dermatitis is a skin condition characterized by loose, greasy or dry, white to yellowish scales with associated reddened skin. Cradle cap is the term used when seborrheic dermatitis affects the scalp of infants.
Seborrheic Keratoses: Seborrheic keratoses are raised growths on the skin. Seborrheic means greasy and keratosis means thickening of the skin. There may be just one or clusters of dozens. They are usually start off light tan, and then may darken to dark brown or nearly black. They may be oval spots a fraction of an inch across, or form long Christmas tree like patterns on the torso inches long.
The consistent feature of seborrheic keratoses is their waxy, pasted-on or stuck-on look. The look is often compared to brown candle wax that was dropped onto the skin.
Telangiectasia: Small, unsightly red, purple or blue blood vessels found along the surface on the face, upper chest, neck and rarely on other parts of the body. Similar veins are found on the legs but called spider veins.
