Also known as skin abscesses, boils form as a result of a cut or break in the skin, which leads to a bacterial infection. They are characterized as a red, tender area with a painful, pus-filled center that can open spontaneously or by surgical incision. Some boils are caused by an ingrown hair. Others are caused by plugged-up sweat glands, such as some types of cystic acne. Anyone can get a boil. They grow quickly and are usually painful until they drain. However, left alone a boil will naturally come to a head and burst open, allowing the pus to drain and the skin to heal. People with weakened immune systems are more susceptible to boils than the general population.

Boils tend to occur on parts of the body that have hair or sweat glands and are exposed to friction, typically on the face, neck, armpits or buttocks. There are a variety of different types of boils:

Furuncle or Carbuncle. These abscesses are caused by the Staphylococcus aureus bacterium. A furuncle is an individual boil; carbuncles are deep clusters of boils that most often form on the back of the neck, shoulders or thighs.

Pilonidal Cyst. An infected hair follicle around the buttocks area caused by long periods of sitting. Pilonidal cysts almost always require medical treatment.

Hidredenitis Suppurativa. These are multiple abscesses that form from blocked sweat glands in the armpits or groin areas.

Cystic Acne. These boils are situated more deeply into skin tissue than the more superficial forms of acne. It typically occurs among teenagers.

Boils respond well to home remedies. To promote healing, apply heat to the boil in the form of hot soaks or compresses. Keep the area clean, apply over-the-counter antibiotics and then cover with gauze. Do not puncture or squeeze the boil because it can lead to further infection. If the boil does not go away within two weeks, is accompanied by a fever or is painful, contact your dermatologist. The doctor will clean, lance and drain the boil and prescribe an antibiotic to alleviate the infection.

Candidiasis is the medical term for yeast infections in the body. There are three forms of candidiasis that relate specifically to the skin:

Oral Candidiasis (Oral Thrush). This infection is characterized by lacy, white patches on top of reddened areas that occur on the tongue, throat or elsewhere in the mouth. It is usually accompanied by a fever, colic or diarrhea. Oral thrush can be painful and lead to an uncomfortable burning sensation in the mouth. People who are diabetic, have suppressed immune systems, patients undergoing antibiotic or chemotherapy treatment and denture wearers are more susceptible to this infection. It is particularly important to catch it early in infants and children. Because of the discomfort caused by oral thrush, they may stop eating and/or drinking.

Diaper Rash. Candidiasis breeds in warm, moist environments and in the natural creases of the skin. Some diaper rashes are bacterial, but many are caused by yeast infections. To treat diaper rash, use over-the-counter powders and ointments and antifungal creams and lotions. Plan on frequent diaper changes to give the skin a chance to be exposed to air regularly. If diaper rash doesn’t abate in seven to 10 days, contact your dermatologist.

Candidal Intertrigo. This yeast infection occurs in moist overlapping skin folds, such as areas in the inner thighs, armpits, under the breasts, below the belly, behind the ears and in the webbed spaces between the fingers and toes. It is more common among people who are overweight. It is characterized by red, raw skin surrounded by scaling and, in some cases, lesions that itch, ooze or hurt. Candidal intertrigo is treated with medicated topical creams.

Scabies is a harmless but very itchy and highly contagious skin condition caused by mites that burrow into the skin and lay eggs. Symptoms include a severe itch, often worse at nighttime, and thin burrow tracks made of tiny bumps or blisters on the skin. Humans are allergic to the mites, which is what causes the itching.

Typically, scabies appear in folds of the skin, such as the armpits, around the waist, inside the wrists, between the fingers, on the soles of feet, on the back of knees or on inner elbows. In children, they more commonly appear on the face, scalp, neck, palms and soles. Scabies is spread through direct contact with an infected person or by sharing clothing and linens. It is so contagious that frequently when one person in a family is diagnosed with scabies, all family members are treated for it. It takes about 21 days for eggs to mature and new mites to begin burrowing through the skin.

Generally a visual examination of the skin is all that is needed to diagnose scabies. However, your dermatologist may take a small scrape of the skin to examine under a microscope. The typical treatment is prescription medicated creams applied liberally all over the body. It takes a few days of treatment before the sensation of itchiness begins to go away.

To help prevent further spreading, be sure to clean all clothes and linen in hot water and dry with high heat. Dry clean items you cannot machine wash in this manner or place the item in a sealed plastic bag and put it away for two weeks. The mites will die without a food source for this length of time.
