A dermatofibroma is a common growth on the skin that has no known cause. Dermatofibromas can be found anywhere on the body, but they most often develop on the extremities, with the lower legs being the most common place to find them. They are usually round, brownish to red-purple, and feel like hard lumps under the skin. While dermatofibromas are usually painless, there can be some itching or tenderness to touch.
Dyshidrotic eczema (dyshidrotic dermatitis) is an itchy rash that appears as small fluid-filled blisters on the hands and feet. It is not known what causes dyshidrotic eczema. Sweating does not seem to cause the condition, although the term "dyshidrotic" refers to abnormal sweating. The lesions of dyshidrotic dermatitis are extremely itchy, and the condition often comes and goes (episodic), with episodes being more common in warm weather.
Sunburn is damage to the top layers of the skin caused by overexposure to ultraviolet (UV) light. Most commonly, the light source is the sun, but tanning beds and some intense heat sources, such as welding tools, can also produce a sunburn. The sunburn usually becomes apparent within 24 hours of exposure; the skin becomes red, warm, and tender, and the person may feel dizzy or ill. Sometimes the skin may blister and peel.Experiencing a sunburn raises the lifetime risk of developing skin cancer. Sunburn and sun exposure also increase wrinkling and other signs of premature aging in the skin. Even a tan is dangerous to the skin, as many doctors consider a tan to be an early sunburn. The best protection is to avoid the sun, especially during the peak hours of 10 AM to 3 PM. Always wear sunscreen on exposed skin with an SPF of at least 30. Additionally, it is important to know that you can get a sunburn through certain clothing and that tanning beds are a source of the same light that cause burns, premature aging, and skin cancer.
Alopecia areata is an autoimmune condition resulting in hair loss. The immune system of the body mistakenly stops hair growth for unknown reasons. Hair loss may be patchy or sparse and may involve the rest of the body in addition to the scalp. Hair in most people spontaneously regrows, though recurrences of the condition are also typical. Genetic and environmental factors play a role in hair loss; the condition may be seasonal as well.
Perioral (which literally means "around the mouth") dermatitis is a facial rash that resembles acne but is specifically located on the skin around the lips. It is red and can be bumpy or scaly. There are usually several causes of this condition including: Chronic use of topical steroid creams. Inhaled prescription steroid sprays via the mouth or nose. Overuse of facial creams and/or moisturizers.
Pruritic urticarial papules and plaques of pregnancy (PUPPP) is the most common skin condition of pregnancy. Typically, women affected by PUPPP develop red, itchy bumps on the belly near stretch marks (striae) during their third trimester. PUPPP usually gets better within a few weeks after delivery, does not affect the health of your baby, and has no long-term consequences for you.
Sunburn is caused by the skin's reaction to ultraviolet light exposure. It appears as reddening and tenderness of the skin and usually occurs between 12 and 24 hours after the exposure. It can develop blisters and shedding of the outer layer of skin. Some oral medications used for other medical conditions, most commonly hydrochlorothiazide (a blood pressure medication) may make the skin more sensitive to sunburning.First Aid GuideIf you have suffered a sunburn:Further direct sun exposure should be avoided for a few days. Cool water or cool milk soaks may help cool and soothe the affected areas. Acetaminophen and ibuprofen can help decrease the redness and pain. Applying a greasy cream or ointment may actually make the pain worse by trapping the heat on the skin. Drink a lot of fluids.Do not attempt to break any blisters that may form; you can cover these with gauze if necessary. If any break on their own, a topical antibiotic ointment can be applied. A moisturizer can help with skin peeling afterward. Avoid topical products that end in "-caine" as they can sometimes further irritate the skin.Prevention is very important. To reduce risk of skin cancer later in life, sunburns should be prevented.Avoid direct sun in the middle of the day (10 AM to 3 PM). Remember: snow and water reflect light to the skin, and clouds still let a lot of light through, so you may still be exposed to ultraviolet light even on cloudy days. Use a hat with a wide brim. A baseball hat does not give much protection. Cover up with tightly woven clothing. Some manufacturers make specialty clothing with a high sun protection factor (SPF) rating, or you can purchase a special ingredient to be added to your washer that can "wash" SPF into your clothing. Use sunscreen on all exposed skin areas, including the lips, before going outdoors. A broad spectrum (blocks UVB and UVA light), with an SPF of at least 30, is best. Apply generously 30 minutes before going outdoors, and reapply every 2 hours or after swimming or sweating a lot. Do not use tanning beds!
Cradle cap is the common name for seborrheic dermatitis affecting the scalp of newborns. It is a very common skin disorder affecting the oil-rich parts of the skin, including the face, ears, and scalp, and it is often seen in babies up to 3 months of age. The skin becomes flaky and inflamed, and a yellowish scale can accumulate. If the scale is picked off, the skin underneath will look pink or red. Cradle cap itself is not serious, but the affected areas can become infected if not treated properly. The cause of cradle cap is related to overgrowth of normal skin yeast including Pityrosporum and Candida.
Since both moles and melanoma come from melanocytes, how can you tell the difference between a normal mole and a melanoma?
I’m a pediatric dermatologist who specializes in the care of severe inflammatory diseases such as psoriasis and atopic dermatitis. These conditions can impair the overall health, development, and quality of life of affected children.
Question: Is it bad to treat itchy skin with hydrocortisone, because it merely treats the itch (if even that) and not the underlying cause?
How can I get rid of the scaly skin and rash from psoriasis?
Dermatologists have many strategies and tools available to treat skin conditions. One treatment that is very common in dermatology clinics is prescribing topical steroids. Steroids are used to treat common skin conditions such as eczema, psoriasis, and contact dermatitis.
While the ideal scenario is to avoid getting mosquito bites in the first place, that’s certainly easier said than done. But here’s a helpful preventive tip: about 30 minutes before you go outside, take Claritin® or Zyrtec® to get antihistamine into your system before your first encounter with a mosquito. I find I have a very mild reaction if I’m bitten, with little swelling, redness, or itching.
Psoriasis can be a very upsetting diagnosis, but you should know that you are not alone. Around 7 million people (2-3%) Americans are affected by psoriasis. People with psoriasis have thickened, red, and often scaly patches on their skin. Psoriasis is very likely to run in families, but it can also be triggered by certain situations, such as emotional stress, injury to the skin, infection, as well as taking certain medications. The exact cause of psoriasis is unknown, but it seems to be caused by errors in how the immune system functions. Recently, many celebrities have announced that they are afflicted by psoriasis. From Kim Kardashian to CariDee English (winner of America's Next Top Model in 2006), women famous for their beauty have all of the same treatment options available to them as anyone else.
Developing an itchy rash after a hike in the woods or a day of working in the yard is not particularly surprising. An inadvertent brush with poison ivy or poison oak and the annoyingly itchy rash that develops is a common summertime problem in the Eastern US. But developing similar symptoms after preparing a fresh meal in your kitchen seems unexpected. As it turns out, it’s not so rare.
