Perioral dermatitis is an acne-like condition of unknown cause. Some possible causes are the use of topical corticosteroid creams, cosmetic products, oral contraceptives, fluoride and anti-tartar ingredients in dental products, and it tends to occur in those prone to eczema.
A kerion is a scalp condition that occurs in severe cases of scalp ringworm (tinea capitis). A kerion appears as an inflamed, thickened, pus-filled area, and it is sometimes accompanied by a fever.The underlying condition, scalp ringworm, is a usually harmless fungal infection of the scalp and hair that occurs as scaly spots and patches of broken hair on the head. Ringworm of the scalp is most commonly seen in children. Though several different species of fungus may cause scalp ringworm, they are generally known as dermatophytes. Scalp ringworm may be acquired by direct contact with infected people or with contaminated objects that have been handled by infected people (such as combs, pillows, and sofas). Most commonly, scalp ringworm infections are caused by dermatophytes that prefer to grow on humans. Less commonly, the fungus may be spread from infected animals (zoophilic dermatophytes) or from the soil (geophilic dermatophytes).Kerions usually occur in people who have been infected with zoophilic dermatophytes. A kerion is believed to be an overly active response of the immune system or an allergic reaction to the fungus.
Folliculitis is a skin condition caused by an inflammation of one or more of the depressions in the skin that hold hair (hair follicles). It usually occurs in areas where the skin is irritated by friction, such as rubbing from clothes. In most instances of folliculitis, the inflamed follicles are infected with bacteria, especially the type called Staphylococcus, that normally live on the skin.The most common causes of damage to hair follicles, leading to infection, include:Friction from tight clothing A pre-existing skin condition such as eczema, acne, or other inflammation of the skin (dermatitis) Injuries to the skin such as surface scrapes (abrasions) Prolonged contact with plastic bandages or adhesive tape Irritation from shaving
Hidradenitis suppurativa is a chronic skin condition characterized by blockage of the sweat glands and subsequent inflammation and infection of the deeper skin structures. In people who are prone to hidradenitis suppurativa, the sweat glands of the armpit, belly, buttocks, and/or groin become clogged, causing large, tender red bumps to grow in these areas. The bumps represent inflammation, and over time these will become infected with bacteria; multiple bumps can grow together under the skin into large, painful cysts. These cysts can reach the surface of the skin and drain pus. The cycle of plugging, enlargement, and draining will eventually lead to scarring of the skin.There is no cure for hidradenitis suppurativa, but your doctor can help you develop a strategy for treating existing lesions and preventing new ones.
Acne vulgaris is the medical term for the very common skin condition known as blemishes, pimples, zits, and spots. Acne is "multifactorial," meaning that many different factors contribute to the problem. These factors include overgrowth of normal skin bacteria (so some acne is treated with antibacterial creams or pills), plugging of follicles (so some acne is treated with creams to promote clearing of follicles), and overproduction of natural oils (again, there are creams to treat this cause). These coupled with the normal hormonal changes of adolescence are the major causes of acne. Other factors include medications such as lithium, cortisone, and seizure medications; stress; and an unhealthy diet. Acne is often hereditary, meaning it runs in families. Acne is not caused by dirt, though skin that is irritated by environmental exposures may be more inflamed in general. Almost all acne can be improved by simple measures and treatments that your doctor can advise. Many people are bothered by their acne and embarrassed to talk about it, but it is very important to discuss it with your doctor because he/she will be able to give you tips and prescribe products that can make a big difference.
Babies can develop blemishes on their face that looks exactly like acne commonly seen in teens. Although the cause of baby acne is unknown, it may be the result of maternal or infant hormones (androgens) stimulating glands in the face to produce oil, or sebum. Baby acne can essentially be divided into 2 groups: neonatal acne, which affects babies in their first month of life; and infantile acne, which typically affects babies 3–16 months of age. Neonatal acne that is confined to the face is called benign cephalic pustulosis, while infantile acne is usually more severe than neonatal acne and consists of more lesions. The later form may last a few weeks to a few months, but most cases usually resolve by age 3.
Rosacea, sometimes called adult acne, is a chronic inflammation of the face of unknown cause and without a permanent cure. Four different types of rosacea have been described:"Red face" rosacea, with a tendency to face flushing (or blushing), which can progress to a persistent redness of the nose or central face "Acne"-like bumps and/or pus-filled lesions (papulopustular rosacea), with or without a red face or flushing Rhinophyma – slow enlargement of oil glands and skin thickening of the nose and sometimes other face areas, usually in men Eye problems (ocular rosacea), which may occur before skin changes – a burning or gritty feeling may be present as well as reddening of the eyes and lids
Tinea infections are commonly called ringworm because some may form a ring-like pattern on affected areas of the body. Beard ringworm (tinea barbae), also known as tinea sycosis or barber's itch, is a fungal infection of the skin, hair, and hair follicles of the beard and mustache area. Beard ringworm may be passed to other people by direct contact with infected people or animals, with contaminated objects, or from the soil.Although beard ringworm is most common in men, it may also affect women who have dark, coarse hair on their faces and necks.
Whether you are fortunate to have clear skin or fighting in the battle against acne, Skinsight would like to enlighten you about acne and the different kinds that are out there. Believe it or not there are different types of acne affecting a wide variety of people every day, such as picker’s acne, rosacea, and acne keloidalis nuchae. For acne awareness month, we have special articles, slide shows, and discussion forums dedicated to the skin condition that affects over 85% of Americans at some point.
Acne is actually a wide variety of complex disease states, from small bumps to red inflammatory nodules and pustules, all influenced by genetic and hormonal makeup. To help understand it, we start with the fact that the human body is covered with millions of hairs, the vast majority so small they can’t be seen. But you can see the pores where the hairs protrude. And that’s where the trouble begins.
An itchy scalp is very common, particularly in adults, and may or may not be due to any disease. If there is absolutely nothing visible accompanying an itchy scalp or just a few flakes of dry skin, you may have a mild case of dandruff.
Staphylococcus aureus, commonly known as "staph," is a bacterium that can live on a person's skin. In fact, approximately 20-30% of healthy people are staph carriers. These people are said to be "colonized" by the bacteria, but they are not considered to be ill with an infection.
There are a few relatively common skin lesions that are painful or tender in children. Probably the most common cause of a painful bump in a child during the summer months is an insect bite reaction. Bees, wasps, hornets, and also spiders can cause acutely painful skin lesions.
