Types Of Skin Rashes

A rash indicates an abnormal change in skin color or texture. Rashes are usually caused by skin inflammation, which can have many causes. There are many types of rashes, including eczema, granuloma annulare, lichen planus, and pityriasis rosea. Eczema and Your Skin Eczema is a general term that describes several different conditions in which skin is inflamed, red, scaly, and itchy. Eczema is a common skin condition, and atopic dermatitis (also called atopic eczema) is one of the most common forms of eczema. Eczema can occur in adults or children. The condition is not contagious. What Causes Atopic Eczema? The cause of atopic eczema is not known, but the condition often affects people with a family history of allergies. Many individuals with eczema also have hay fever and/or asthma or have family members with those conditions. Some factors can trigger a flare-up of eczema or make eczema worse, but they do not cause the condition. Eczema triggers include stress, skin irritants (including soaps, skin care products, or some fabrics), allergens, and climate/environment. What Are the Symptoms of Atopic Eczema? The appearance of eczema can vary from person to person. In adults, eczema occurs most frequently on the hands and elbows, and in “bending” areas such as the inside of the elbows and back of the knees. In young children, eczema is often seen on the elbows, knees, face, neck, and scalp. Signs and symptoms of atopic eczema include: Itchiness Skin redness Dry, scaly, or crusted skin that might become thick and leathery from long-term scratching Formation of small, fluid-filled blisters that might ooze when scratched Infection of the areas where the skin has been broken How Is Atopic Eczema Diagnosed? Atopic eczema usually is diagnosed with an analysis of a person’s history of symptoms and with an exam of the skin. A doctor might test an area of scaly or crusted skin to rule out other skin diseases or infections. How Is Atopic Eczema Treated? Atopic eczema can be treated with medications, including over-the-counter creams and ointments containing the steroid hydrocortisone (for example, Cortizone-10, Cort-Aid, Dermarest Eczema, Neosporin Eczema). These products may help control the itching, swelling, and redness associated with eczema. Prescription-strength cortisone creams, as well as cortisone pills and shots, are also used for more severe cases of eczema.

Types Of Skin Rashes

Overview Bumps, itching, redness and other skin conditions are very common, and their cause may not be easily identifiable. Rashes can be caused by many things, including plants (poison ivy, for example), allergic reactions to a medication or a food, or an illness (measles or chickenpox, for example). Eczema and hives, both of which are related to allergies, are two of the most common skin rashes. GET RELIEF Find an allergist Search Eczema Eczema, also known as atopic dermatitis, affects between 10 and 20 percent of children and 1 to 3 percent of adults. A common symptom of eczema is dry, red, irritated and itchy skin. Sometimes, especially when infected, the skin may have small, fluid-filled bumps that ooze a clear or yellowish liquid. People with eczema often have a family history of allergies.Learn more about eczema treatments and about identifying potential causes of eczema. Hives Hives (urticaria) are red bumps or welts that appear on the body. The condition is called acute urticaria if it lasts for no more than six weeks, and chronic urticaria if it persists beyond six weeks. Acute urticaria is most commonly caused by exposure to an allergen or by an infection. The cause of chronic urticaria is largely unknown.Learn more about urticaria and how to manage it. Contact dermatitis Contact dermatitis is a reaction that appears when the skin comes in contact with an irritant or an allergen. Symptoms can include a rash, blisters, itching and burning.Soaps, laundry detergents, fabric softeners, shampoos — or even excessive exposure to water — can all cause contact dermatitis. Other items that can cause a reaction are metals (such as nickel, a component of stainless steel and other alloys used to make costume jewelry), adhesives, nail polish, topical medications, plants and latex gloves.Sometimes an allergen won’t cause a skin reaction unless the skin is also exposed to sunlight. This condition is called photoallergic contact dermatitis. It can occur with products such as shaving lotion, sunscreen and some perfumes.Learn more about treating contact dermatitis rashes and about recognizing and avoiding irritants and allergens.

Types Of Skin Rashes

Rashes are one of the most common reasons that parents of small children visit the doctor. In most cases rashes do not indicate a dangerous condition, but in some cases they do. If a child is in good general health and has no other symptoms, you can simply observe the rash for a few days. Many types of rashes will disappear without treatment. If the rash is accompanied by high fever, breathing difficulties, vomiting, or reduced general health (when the child is not acting right), take your child to see a doctor, as it is often difficult to describe rashes over the telephone. One type of rash can have different causes, so let the doctor note what the rash looks like, how widespread it is, how many and how big the marks are, how long the rash has been present, and whether it is itchy.

Continued How Is Granuloma Annulare Diagnosed? The condition is diagnosed by a doctor who may use a skin biopsy to confirm the diagnosis. How Is Granuloma Annulare Treated? Treatment of granuloma annulare often is not necessary, except for cosmetic reasons. In some cases, steroid creams or ointments are used to help the bumps disappear. Some doctors may decide to freeze the lesions with liquid nitrogen or to inject steroids directly into the rings of bumps. Ultraviolet light therapy or oral drugs can be used in severe cases. Lichen Planus and Your Skin Lichen planus is a common skin disorder that produces shiny, flat-topped bumps that often have an angular shape and a reddish-purplish color. Lichen planus can occur anywhere on the skin but is often found on the insides of the wrists and ankles, the lower legs, the back, and the neck. Some people have lichen planus inside their mouth, genital region, hair, and nails. Thick collections of bumps may occur, especially on the shins. Lichen planus occurs most often in adults aged 30 to 70. It is not common in very young or elderly people. What Causes Lichen Planus? In most cases, the cause of lichen planus is not known. However, lichen planus is linked to hepatitis C infection in some cases. Medications to treat high blood pressure, heart disease, and arthritis can cause lichen planus-type rashes that are allergic reactions to those drugs. Lichen planus is not contagious. What Are the Symptoms of Lichen Planus? Signs and symptoms of the condition include shiny, flat-topped bumps that are purple or a reddish-purplish color. When it appears on the scalp, lichen planus may cause hair loss. Lichen planus of the nails can cause brittle or split nails. How Is Lichen Planus Diagnosed? A doctor can diagnose lichen planus by its distinctive appearance or with the use of a skin biopsy. In a skin biopsy, a small bit of skin is taken from the affected area and is sent to a lab for testing. How Is Lichen Planus Treated? Although lichen planus cannot be cured, its symptoms can be treated with anti-itch products such as antihistamines (for example, Benadryl, or diphenhydramine). If lichen planus affects only a small part of the body, medicated cream can be applied to the affected area. Drugs such as steroid injections, prednisone, other drugs to suppress the immune system, or retinoids may be prescribed in more severe cases. Another treatment for lichen planus is light therapy. Talk to your doctor about which treatment is right for you.
