Discover the causes, symptoms, and treatment options for 22 common skin rashes, including fleabites, fifth disease, rosacea, impetigo, ringworm, contact dermatitis, eczema, hand-foot-and-mouth disease, diaper rash, and psoriasis.

Understanding Skin Rashes: Causes, Symptoms, and Treatment

A rash is an area of irritated or swollen skin that can appear in various forms, such as red bumps, scaly patches, or blisters. Rashes can be caused by a wide range of factors, from insect bites to serious medical conditions. It’s important to understand the different types of skin rashes, their causes, and the appropriate treatment options to effectively manage them.

22 Common Skin Rashes Explained

In this comprehensive guide, we will explore 22 common skin rashes, providing detailed information on their characteristics, causes, and treatment approaches.

Fleabites

Fleabites typically appear as small, itchy red bumps, often clustered on the lower legs and feet. They are caused by the bites of fleas and can be more plum-like in color on darker skin tones. Symptoms usually start immediately after being bitten.

Fifth Disease

Fifth disease is a viral illness caused by parvovirus B19, which can result in a distinctive “slapped cheek” rash. Symptoms may include headache, fatigue, low fever, sore throat, runny nose, diarrhea, and nausea. The rash is often more noticeable after a hot shower or bath.

Rosacea

Rosacea is a chronic skin condition that goes through cycles of fading and relapsing. It can be triggered by various factors, such as spicy foods, alcohol, sunlight, and stress. On darker skin tones, the rash may appear as brown or yellowish-brown bumps with a dusky coloration.

Impetigo

Impetigo is a highly contagious skin infection that commonly affects children between the ages of 2 and 5. It typically appears around the mouth, chin, and nose as an irritating rash with fluid-filled blisters that pop easily and form a honey-colored crust. On darker skin tones, the rash may appear brown, purple, or gray.

Ringworm

Ringworm is a fungal infection that manifests as itchy, circular scaly patches with raised borders. On lighter skin tones, the patches may appear pink or red, while on darker skin tones, they can appear gray or brown.

Contact Dermatitis

Contact dermatitis is a skin irritation that appears hours or days after contact with an allergen or irritating substance. It has visible borders and typically appears where the skin touched the irritant. On darker skin tones, it may be less noticeable and can cause blisters that weep, ooze, or become crusty.

Allergic Eczema

Allergic eczema, also known as atopic dermatitis, may resemble a burn and is often found on the hands and forearms. The skin is itchy, scaly, or raw, and may have blisters that weep, ooze, or become crusty. On darker skin tones, it can cause darker brown, purple, or gray patches.

Hand, Foot, and Mouth Disease

Hand, foot, and mouth disease is a viral infection that usually affects children under the age of 5. It causes painful red blisters in the mouth and on the tongue, gums, palms of the hands, and soles of the feet. On darker skin tones, the spots may appear skin-colored or grayish-brown.

Diaper Rash

Diaper rash is a skin irritation that occurs in the areas that have contact with a diaper. The skin looks red, wet, and slightly lighter or darker than typical skin color, and may feel warm to the touch.

Eczema

Eczema, also known as atopic dermatitis, is a chronic skin condition characterized by dry, rough, flaky, inflamed, and irritated skin. Affected areas may be red and itchy, and hair loss may occur in the affected areas. On darker skin tones, eczema can appear as darker brown or gray patches.

Psoriasis

Psoriasis is an inflammatory skin condition that causes dry, scaly plaques on the skin. It is believed to be an immune system-mediated condition, with genetics also playing a role. The appearance and severity of psoriasis can vary significantly between individuals.

These are just a few of the 22 common skin rashes discussed in this comprehensive guide. Each rash has its own unique characteristics, causes, and treatment approaches. It’s important to seek medical attention if home remedies do not provide relief or if you experience additional symptoms such as fever or dizziness.

Remember, the appearance of a rash can vary depending on skin tone, and it’s crucial to be aware of these differences to ensure accurate diagnosis and effective treatment. By understanding the various types of skin rashes, their causes, and the appropriate management strategies, you can take proactive steps to address and alleviate these skin conditions.

22 Common Skin Rashes, Pictures, Causes & Treatment

A rash is any area of irritated or swollen skin on your body. Rashes are often itchy and painful and can appear differently on different skin tones. While they are often described as red, on darker skin tones, they may be purple, gray, or white.

Rashes have a variety of causes, from bites to chickenpox to serious conditions like drug allergies. Seek medical attention if home remedies do not help or if you also have symptoms such as fever or dizziness.

Contact dermatitis

Contact dermatitis is one of the most common causes of rashes. This type of rash occurs when the skin comes into direct contact with a foreign substance that causes an adverse reaction, leading to a rash. The resulting rash may be itchy, red, or inflamed.

Possible causes of contact dermatitis include:

• beauty products
• soaps
• laundry detergent
• dyes in clothing
• chemicals in rubber, elastic, or latex
• poisonous plants, such as poison oak, poison ivy, or poison sumac

Medications

Taking medications may also cause rashes. They can form as a result of:

• an allergic reaction to the medication
• a side effect of the medication
• photosensitivity from the medication

Other causes

Other possible causes of rashes include the following:

• A rash can sometimes develop in the area of a bug bite, such as a fleabite. Tick bites are of particular concern because they can transmit disease.
• Atopic dermatitis, the most common form of eczema, is a rash that may be more common in people with asthma or allergies. The rash is often reddish, though it can be skin-colored or darker on people with darker skin tones. It can be itchy with a scaly texture.
• Psoriasis is a common skin condition that can cause a scaly, itchy, red, or purplish rash to form along the scalp, elbows, and joints.
• Seborrheic eczema is a type of eczema that most often affects the scalp and causes redness, scaly patches, and dandruff. It can also occur on the ears, brows, or nose. When babies have it, it’s known as cradle cap.
• Systemic lupus erythematosus is an autoimmune disease that can trigger a rash on the cheeks and nose. This rash is known as a “butterfly,” or malar, rash.
• Rosacea is a chronic skin condition of unknown cause. There are several types of rosacea, but all are characterized by redness and rash on the face.
• Ringworm is a fungal infection that causes a distinctive ring-shaped rash. The same fungus that causes ringworm on the body and the scalp also causes jock itch and athlete’s foot.
• Diaper rash is a common skin irritation in infants and toddlers. It can be associated with prolonged exposure to a wet diaper.
• Scabies is an infestation by tiny mites that live on and burrow into your skin. It causes a bumpy, itchy rash.
• Cellulitis is a bacterial infection of the skin. It usually appears as a red, swollen area that is painful and tender to the touch. If left untreated, the infection causing the cellulitis can spread and become life threatening.

Causes of rashes in children

Children are particularly prone to rashes that develop as a result of illnesses:

• Chickenpox is caused by a virus, and the rash is characterized by small itchy bumps and blisters that form all over the body.
• Measles is a viral respiratory infection that causes a widespread rash consisting of itchy, red bumps.
• Scarlet fever is an infection due to group A Streptococcus bacteria that produces a toxin, causing a bright red or skin-tone-colored, sandpaper-like rash.
• Hand, foot, and mouth disease is a viral infection that can cause red lesions on the mouth and a rash on the hands and feet.
• Fifth disease is a viral infection that causes a red, flat rash on the torso, arms, and legs.
• Kawasaki disease is a rare but serious illness that triggers a rash and fever in the early stages and can lead to heart complications.
• Impetigo is a contagious bacterial infection that causes an itchy, crusty rash and yellow, fluid-filled sores on the affected area, such as the face, neck, or hands.

You can treat most contact rashes, but it depends on the cause. Follow these guidelines to help ease discomfort and speed up the healing process:

• Use mild, gentle cleansers instead of scented bar soaps.
• Use warm water instead of hot water for washing your skin and hair.
• Pat the rash dry instead of rubbing it.
• Let the rash breathe. If it’s possible, avoid covering it with clothing.
• Stop using new cosmetics or lotions that may have triggered the rash.
• Apply unscented moisturizing lotion to areas affected by eczema.
• Avoid scratching the rash because doing so can make it worse and could lead to infection.
• Apply an over-the-counter (OTC) hydrocortisone cream to the affected area if the rash is very itchy and causing discomfort. Calamine lotion can also help relieve rashes from chickenpox, poison ivy, or poison oak.
• Take an oatmeal bath. This can soothe the itchiness associated with rashes from eczema or psoriasis. Here’s how to make an oatmeal bath.
• Wash your hair and scalp regularly with dandruff shampoo if you have dandruff along with a rash. Medicated dandruff shampoo is commonly available at drugstores, but your doctor can prescribe stronger types if you need them.

Over-the-counter (OTC) medications

Talk with a healthcare professional, who may recommend OTC medication like ibuprofen or acetaminophen to treat mild pain associated with the rash.

Avoid taking these medications for an extended period because they can have side effects. Ask a healthcare professional how long it’s safe for you to take them. You may not be able to take them if you have liver or kidney disease or a history of stomach ulcers.

Call a healthcare professional if the rash doesn’t go away with home remedies. You should also contact them if you’re experiencing other symptoms in addition to your rash and you suspect you have an illness.

If you don’t already have a physician, you can use the Healthline FindCare tool to find a professional near you.

Go to the hospital immediately if you experience a rash along with any of the following symptoms:

• increasing pain or discoloration in the rash area
• tightness or itchiness in the throat
• difficulty breathing
• swelling of the face or limbs
• fever of 100. 4°F (38°C) or higher
• confusion
• dizziness
• severe head or neck pain
• repeated vomiting or diarrhea

Contact a healthcare professional if you have a rash as well as other systemic symptoms, including:

• joint pain
• a sore throat
• red streaks or tender areas near the rash
• a recent tick bite or animal bite

Your healthcare professional will perform a physical exam and inspect your rash. Expect to answer questions about your:

• rash
• medical history
• diet
• recent use of products or medications
• hygiene

Your healthcare professional may also:

• take your temperature
• order tests, such as an allergy test or complete blood count
• perform a skin biopsy, which involves taking a small sample of skin tissue for analysis
• refer you to a specialist, such as a dermatologist, for further evaluation

Your healthcare professional may also prescribe medication or medicated lotion to relieve your rash. Most people can treat their rashes effectively with medical treatments and home care.

Follow these tips if you have a rash:

• Use home remedies to soothe mild contact rashes.
• Identify potential triggers for the rash and avoid them as much as possible.
• Call a healthcare professional if the rash doesn’t go away with home treatments. You should also contact them if you’re experiencing other symptoms in addition to your rash and you suspect you have an illness.
• Carefully follow any treatments your doctor prescribes. Speak with a healthcare professional if your rash persists or worsens despite treatment.

Rashes are areas of irritated or swollen skin. These areas may become itchy, painful, or dry out.

Skin discoloration is a common rash symptom, which can present differently on different skin tones. Rashes may appear red or pink on lighter skin tones, while on darker skin tones they may be purple, gray, or white.

Causes, Symptoms, Treatment, Picture, and More

A malar rash, also known as a butterfly rash, may have many causes from sunburn to chronic diseases. It can often be cured.

Malar rash is a red or purplish facial rash with a “butterfly” pattern. It covers your cheeks and the bridge of your nose, but usually not the rest of the face. The rash can be flat or raised.

A malar rash can occur with many different diseases and conditions, from sunburn to lupus. It’s most often seen in people with rosacea.

It may be scaly and sometimes itchy, but it doesn’t have bumps or blisters. It may also be painful.

Sunlight triggers this rash. It can appear on other parts of the body that are exposed to the sun if you’re sensitive to sunlight. The rash may come and go, and it can last for days or weeks at a time.

Many conditions may cause a malar rash:

• Rosacea, also called adult acne. Rosacea’s rash is also characterized by pimples and enlarged blood vessels.
• Lupus. A rare condition with a variety of symptoms, it can result in other types of rashes.
• Seborrheic dermatitis. With this condition, the rash could occur on your face and other areas. It also involves scaling of your skin and scalp.
• Photosensitivity. If you’re sensitive to sunlight or get too much sun, you may have a sunburn that looks like a malar rash.
• Erysipelas. Caused by Streptococcus bacteria, this infection can lead to a painful malar rash. It may also involve the ear.
• Cellulitis. This is a type of a bacterial infection affecting the deeper skin layers.
• Lyme disease. In addition to a rash, this disease, resulting from another type of bacterial infection, may also produce flu symptoms, joint pain, and many other problems.
• Bloom syndrome. This inherited chromosomal disorder has multiple additional symptoms, including skin pigmentation changes and mild intellectual disability.
• Dermatomyositis. This connective tissue disorder also causes skin inflammation.
• Homocystinuria. In addition to a malar rash, this genetic disorder may lead to vision problems and intellectual disability.

Rosacea is the most common cause of a malar rash.

It’s also very common in the population. About 16 million Americans are estimated to have rosacea.

Usually the rash is triggered by:

• stress
• spicy food
• hot drinks
• alcohol

With rosacea, you may have:

• redness that spreads to your forehead and chin
• visible broken spider veins on your face
• raised patches of facial skin called plaques
• thickened skin on your nose or chin
• acne breakouts
• red and irritated eyes

The cause of rosacea isn’t known. Scientists are investigating possible factors, including:

• an immune system reaction
• a gut infection
• a skin mite
• the skin protein cathelicidin

About 66 percent of people with lupus develop a skin disease. Malar rash is present in 50 to 60 percent of people with systemic lupus erythematosus, also known as acute cutaneous lupus. Lupus is a somewhat rare condition, likely underdiagnosed due to its complexity.

Other forms of lupus skin disease include:

• discoid lupus, which causes round, disk-shaped sores with raised edges, usually on the scalp and face.
• subacute cutaneous lupus, which appears as red scaly lesions with red edges, or red ring-shaped lesions
• calcinosis, which is a buildup of calcium deposits under the skin that may leak a whitish liquid
• cutaneous vasculitis lesions, which cause small reddish-purple spots or bumps on the skin

A malar rash can have many different causes, and there’s no simple way to tell if your rash is a sign of lupus. Lupus is a complex disease that affects each person differently. Symptoms may start slowly or suddenly. The symptoms also vary widely in severity.

Additional symptoms may include:

• rashes of varying types
• mouth, nose, or scalp sores
• skin sensitivity to light
• arthritis in two or more joints
• lung or heart inflammation
• kidney problems
• neurological problems
• abnormal blood tests
• immune system disorder
• fevers

Having a few of these symptoms doesn’t mean that you have lupus.

Diagnosis of a malar rash can be a challenge because there are many possible causes. Your doctor will take a medical history and review all your symptoms to rule out other possibilities.

If your doctor suspects lupus or a genetic disease, they will order blood and urine tests.

Specialized tests for lupus look for:

• low white blood cell count, low platelets, or low red blood cells, which indicate anemia
• antinuclear antibodies, which are usually a probable sign of lupus
• levels of antibodies for double-stranded DNA and red blood cells
• levels of other autoimmune antibodies
• levels of proteins that have immune functions
• kidney, liver, or lung damage from inflammation
• heart damage

You may also need a chest X-ray and echocardiogram to look for heart damage. A diagnosis of lupus depends on many test results, not just one marker.

Treatment for malar rash depends on the severity of your rash and the suspected cause. Because sunlight is often a trigger for malar rash in general, the first line of treatment is to limit your sun exposure and use sunscreen rated at SPF 30 or more. If you have to be in the sun. wear a hat, sunglasses, and protective clothing in addition to sunscreen. Learn more about choosing a sunscreen.

Other treatments depend on the cause of the rash.

Rosacea

Rosacea malar rash treatment may include antibiotics, special skin creams to heal and repair your skin, and possible laser or light treatments.

Bacterial infection

If you have a bacterial infection, you’ll be prescribed a topical antibiotic. For systemic bacterial infections — that is, infections affecting the entire body — you may need oral or intravenous antibiotics.

Lupus

Lupus malar rash treatment depends on the severity of your symptoms. Your doctor may prescribe:

• steroidal creams for your rash
• topical immunomodulators, such as tacrolimus ointment (Protopic)
• nonsteroidal drugs to help with inflammation
• antimalarials such as hydroxychloroquine (Plaquenil), which has been found to suppress inflammation
• immunosuppressive drugs, in more severe cases, to treat the rash and prevent its recurrence
• thalidomide (Thalomid), which has been found to improve lupus rashes that don’t respond to other treatments

Home remedies

You can take steps to keep your face comfortable while the rash heals.

• Wash your face with a mild, unscented soap.
• Apply small amounts of mild oils, cocoa butter, baking soda, or aloe vera gel to the rash to soothe the skin.

A malar rash may have many causes from sunburn to chronic diseases.

Rashes caused by bacterial infections can be cured. On the other hand, rosacea and lupus are both chronic diseases, for which there currently aren’t any cures. Rashes from these conditions improve with treatment, but can flare up again.

See your doctor if you have a malar rash so that they can determine the underlying cause and start you on the right treatment.

Most common types of allergic rash

Skin allergy is the most common type of allergic reaction in infants. This is because the skin of babies is very delicate and sensitive. Therefore, any stimulus can cause allergic rash on her.

Allergic rash in children most commonly presents as atopic eczema, papular urticaria, heat rash, urticaria, or intertrigo.

Thus, atopic eczema is characterized by red, itchy rashes that may consist of tiny red bumps. This allergic rash in a baby typically develops after 2 months of age and is, in fact, an inflammatory skin condition. Eczema is the most common version of childhood rash caused by allergies.

However, allergic rash in infants can also be caused by insect bites such as pet fleas, ticks, bedbugs and mosquitoes.

It is called papular urticaria. Most often, such a reaction manifests itself in open areas of the body, such as hands, face and neck. But in babies with a strong reaction, hives can appear all over the body, giving the impression that there are many insect bites, when in fact, there may be only one bite.

Another common type of childhood skin reaction is heat rash. It is also called miliaria or “potnichka”. It is usually seen on the face, neck, back, armpits, or buttocks. Such a rash on the skin appears when the child overheats. In most cases, it does not require treatment and goes away on its own.

An allergic reaction such as urticaria may disappear on its own. True, in some cases it will take several hours, while in others the urticaria can last for several weeks.

Antihistamines for children will help speed up the healing process.

In general, urticaria resembles stinging nettles. It can take on various sizes and shapes and develop anywhere in the body.

But intertrigo appears in skin folds. Therefore, this problem is more likely to affect chubby babies. At the same time, the most common place of its appearance is the neck. As an allergy develops, skin-to-skin rubbing can cause pain.

Causes of allergies in infants

Allergy is a hypersensitivity reaction of the immune system to one or another allergen: food, pollen, dander, dust, etc. In response to an irritant, the immune system releases inflammatory mediators such as histamine, serotonin, and bradykinin, which leads to an inflammatory response.

Due to the sensitivity of the skin of infants, allergies and similar contact dermatitis in them can be provoked by various irritants. For example, Allergy on the buttocks of a child is a frequent consequence of a diaper that has not been changed in time.

Food, soaps, detergents and even saliva can also cause breakouts.

For example, intertrigo occurs as a reaction to excessive moisture : saliva and sweat that accumulate in the folds of the child’s skin. Because these skin areas are less exposed to the air, moisture stays in them longer, making the baby vulnerable to infection.

But in the development of eczema, an important role is played by the genetic predisposition to this problem. Synthetic clothing, certain detergents, food allergies, and exposure to irritants such as dust, smoke, and sweat can also cause this rash.

Sweaty skin is the main cause of miliaria (heat rash). Because babies’ sweat glands are small, their bodies don’t have the ability to regulate their temperature, making them prone to heat rash. Therefore, tight clothing, or even a seat belt in a car seat that fits snugly against the body, can cause a rash in warm, humid weather.

Sudden changes in temperature can also cause hives. Although insect bites and certain types of food are also often associated with it. Sometimes urticaria also occurs in infectious or viral diseases.

But be careful: skin rashes in a small child can be a sign of an infectious or viral disease.

If rash is accompanied by high fever, vomiting, lethargy, or other unusual symptoms, consult physician for conditions such as chickenpox, measles, meningitis, etc.

At the same time, sometimes a rash in a baby can be a variant of the norm. For example, in the first month of life, a child often develops so-called baby acne. They are the result of hormonal changes and over time – approximately in the third month – pass on their own.

Allergic rash symptoms

If a child develops reddish, swollen patches anywhere on the body after eating a certain food (most commonly cow’s milk, eggs, peanuts, or seafood) or after significant changes in temperature, it is most likely urticaria .

Antihistamines may help in this case . But the best option would be to eliminate exposure to the allergen.

For example, if a food allergy is suspected, an elimination diet is prescribed. If the child is fully breastfed, the diet should be followed by the mother, temporarily excluding potential allergens from her menu.

Other allergic reaction in a child – eczema or atopic dermatitis , most often manifests itself as a rash on the cheeks, neck, and also in the folds of the skin. However, it can also occur throughout the body. Eczema is characterized by a red and itchy rash. If a child constantly scratches such a rash, characteristic pigmentation may occur in these areas. To prevent this condition, wash and moisturize your baby’s skin well with products with neutral odors.

In the case of papular urticaria, the rash may also be very itchy. The reaction itself begins as a small raised tubercle. Over time, this rash can enlarge and become reddish-brown.

A topical steroid cream, which is used to relieve itching, helps here. An antihistamine may also relieve the condition, but should be given at night. Antihistamines for infants are prescribed in the form of drops. Such allergy drops for children should be new generation drugs, because they have fewer side effects.

But be careful: if a child scratches the skin, it can lead to infection. The doctor may then prescribe an antibiotic cream.

Red or reddish-brown tint, as in papular urticaria, may also have intertrigo rash . In this case, the affected areas of the skin can also itch, and sometimes smell unpleasant. Sometimes the skin may become cracked.

To get rid of such a rash, the skin, especially the folds, must be washed well with water and dried. Vaseline or a zinc oxide barrier cream is then applied to it to speed up the healing process. In severe cases, steroid drugs are prescribed.

But miliaria rash looks like tiny red bumps. This condition can also be manifested by blisters filled with pus, which is formed due to blockage of the sweat ducts.

Heat rash in a child , if the cause of the overheating is removed, usually goes away on its own in three to four days.

Allergy to the buttocks in a child

Allergy to the buttocks in a child may be a symptom of diaper dermatitis. Other symptoms include swelling of the skin and red spots that usually appear on the rounded part of the buttocks.

This rash usually improves with frequent diaper changes and the use of baby powder or zinc ointment.

However, sometimes a child’s butt allergy may actually be a yeast rash caused by a fungus. Its signs are pink blotches that usually appear on the skin folds of the child. They may be accompanied by small pink dots or ulcers around the edge. This disease is treated with an antifungal cream.

To prevent these and other skin manifestations, try to avoid situations where the child sweats. The skin must be clean and dry. But don’t use soap too often. It can over-dry the skin. Therefore, it is better to wash the child with plain water, and after bathing, moisturize the skin with baby cream or oil.
