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.

There are many different causes of rashes. Here’s a list of 22 potential causes with pictures.

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 gets worse despite treatment.

Rash on Hands and Feet: Common Causes and Treatment

Rashes are earmarked by a change in the color and texture of your skin. They may have blisters, and they may itch or hurt. Rashes that break out on your hands and feet have a wide range of underlying causes.

We’ll explore some of the common conditions that cause rashes to occur on the hands and feet. We’ll also look at treatment options you can try at home, or under a doctor’s care.

Common causes of rashes on the hands and feetOverview
hand, foot, and mouth diseasecontagious infection caused by several viruses, including the coxsackie virus
granuloma annulare chronic, degenerative skin condition with an unknown cause
dyshidrotic eczema (dyshidrosis, pompholyx) itchy, common form of eczema
impetigocontagious, bacterial skin infection
hand-foot syndrome (acral erythema or palmar-plantar erythrodysesthesia)side effect of certain chemotherapy drugs
athlete’s footcontagious fungal infection

Rashes on the hands and feet can be caused by environmental factors, such as irritants or allergens. They may also be the result of medical conditions or infections.

Some common causes of rashes on hands and feet include:

Hand, foot, and mouth diseas

e

Hand, foot, and mouth disease is a contagious infection caused by several viruses, including the coxsackie virus. Anyone can get hand, foot, and mouth disease, although it most commonly occurs in babies and children.

This condition causes a rash on the hands and feet, as well as sores in the mouth and on the tongue. You may experience fever and a sore throat with this condition.

The hand and foot rash caused by this condition sometimes causes blistering to occur, and may be painful, but not itchy. In some instances, it may appear on the buttocks, as well.

Granuloma annulare

Granuloma annulare is a chronic, degenerative skin condition with an unknown cause. There are five recognized types:

  • localized granuloma annulare
  • generalized or disseminated granuloma annulare
  • subcutaneous granuloma annulare
  • perforating granuloma annulare
  • linear granuloma

The most common type, localized granuloma annulare, causes rings of flesh-toned, red, or yellow nodules to form on the feet, hands and fingers.

These nodules are small and hard, but do not typically itch. The rings usually clear up on their own without treatment, within a few months to two years. They may, however, come back.

Granuloma annulare is more common in women than in men, and tends to occur during young adulthood.

Dyshidrotic eczema (dyshidrosis, pompholyx)

This very itchy, common form of eczema causes deep-set blisters on the palms of hands, edges of fingers, soles and sides of feet, and toes. The blisters can become large and painful, and may last for several weeks.

Dyshidrotic eczema outbreaks often coincide with seasonal allergies, during spring and summer. It’s more common in women than in men. This condition is not curable, but its symptoms can be successfully treated. It’s not contagious.

Impetigo

This very contagious, bacterial skin infection begins with an oozing rash of red sores around the mouth and nose that can be spread to the hands and feet via touch. When the sores burst, they develop brownish-yellow crusts.

The rash can be itchy, and painful. Impetigo most commonly occurs in infants and children. Itching and soreness are other symptoms.

Hand-foot syndrome (acral erythema or palmar-plantar erythrodysesthesia)

This condition is a side effect of certain chemotherapy drugs used for cancer treatment. It’s earmarked by pain, swelling, and redness in either or both the palms of the hands and soles of the feet. It can also cause tingling, burning, and blisters. In severe cases, deeply cracked skin and extreme pain may occur.

Athlete’s foot

Athlete’s foot is caused by a contagious fungal infection. It usually starts between the toes, and spreads to the entire foot. This condition is earmarked by a scaly, red rash that itches.

In some instances, athlete’s foot can spread to the hands. This is more likely to happen if you pick at or scratch the rash on your feet.

Athlete’s foot is caused by keeping very sweaty feet trapped in shoes. It can also be transmitted on locker room and shower floors.

Many hand and foot rashes can be treated at home, but some require medical treatment, based on their underlying cause and severity.

There are a number of over-the-counter and at-home rash treatments that may help alleviate itching and pain, plus reduce the appearance of the rash. You may have the best success by combining several.

Home treatments include:

  • topical application of over-the-counter hydrocortisone cream
  • topical application of anti-itch medications containing pramoxine
  • topical application of lidocaine, or other types of pain medication
  • cold compresses
  • oral antihistamines
  • oral pain medication, such as acetaminophen or ibuprofen
  • cool oatmeal baths
  • applying unscented moisturizing cream
  • avoiding triggers, such as pollen

If you have dyshidrotic eczema: Avoid cobalt and nickel in food and in everyday items. Foods that contain cobalt include clams, fish, and leafy green vegetables. Foods that contain nickel include chocolate, soy beans, and oatmeal.

If you have impetigo: Cleaning and soaking the blisters and removing the crusts every few days may help. Cover the area with an antibiotic cream and loose dressing after treating.

If your rash does not clear up, your doctor may recommend the following:

  • corticosteroid injections
  • liquid nitrogen, applied directly to the rash to freeze the area and remove lesions
  • oral medication to reduce immune system reactions
  • light therapy using a laser
  • blister draining
  • antibiotics, if infection occurs

Any rash that’s painful, accompanied by fever, or looks infected should be seen by a doctor. You should also seek medical attention for a rash that doesn’t clear up easily with treatments you use at home.

Your doctor may be able to diagnose the rash visually after taking an oral history. In some instances, you may also expect diagnostic tests, such as:

  • skin culture
  • allergy tests
  • skin lesion biopsy

If your child has a rash that does not clear up within one or two days, they should be seen by their pediatrician. This will help determine the cause of the rash, and provide relief for their symptoms.

If your child has sores in their mouth or throat that prohibit them from drinking, they should also be seen by their doctor, to avoid complications such as dehydration.

Since conditions such as hand, foot, and mouth disease and impetigo are contagious, make sure to wash your hands after caring for your child.

If you’re a cancer patient experiencing hand-foot syndrome, let your doctor know. Your doctor may be able to change the dosage or type of medication you’re taking.

Rashes on the hands and feet can be caused by a wide range of conditions. These types of rashes sometimes clear up on their own, or they are treated easily at home.

Depending on their underlying conditions, some rashes will respond better to treatments performed or prescribed by a doctor. See your healthcare provider for any rash that’s accompanied by fever or pain.

Rash COVID-19 | A rash can be a symptom of coronavirus

The onset of COVID-19 can be associated with the appearance of various types of skin lesions. They resemble papules, nodules, vesicles, excoriations (abrasions), scales, ulcers, some are in the form of spots, indurations or nets. The rash can occur in people who are asymptomatic with COVID-19. In 21% of patients, dermatosis was the only symptom of SARS-CoV-2 infection. At the same time, 17% of patients reported skin rash as the first manifestation of the disease.

The incidence of skin symptoms of COVID-19 is difficult to determine. There is also no known relationship between some skin symptoms and disease severity. In addition, it cannot be ruled out that in some patients, skin lesions may be a manifestation of a reaction to multiple treatments for COVID-19.

Covid-19 rash - where does it appear?

Skin lesions are often the body's response to viral infections. However, in the case of COVID-19, doctors are surprised by the variety of skin rashes, the time of their appearance and location.

Skin lesions associated with COVID-19 occur on various parts of the body, such as around the mouth, trunk, limbs, legs and arms. They are not always accompanied by itching.

What does the rash of COVID-19 look like?‎

The rashes associated with Covid-19 are varied and similar to skin lesions associated with other viral diseases, according to a study conducted by specialists in Spain. They noted that skin changes did not correlate with the severity of the infection: some were accompanied by asymptomatic COVID-19, others - severe forms of infection.

Five types of rash were noted:

• Irregular frostbite-like patches on the arms and legs, sometimes accompanied by soreness and itching. Mostly encountered in young patients with a mild course of the disease, appeared in the later stages and lasted about 12 days. Registered in 19% of cases.

• Focal eruption in the form of small vesicles, which can cause itching, located on the body and upper and lower limbs. Occurs at the time of the onset of any other symptoms and occurs at 9% of cases in middle-aged patients; kept for 10 days.

• Urticaria-like patchy eruption, white or pink, often itchy. They were noted in 19% of cases, mainly on the body, but also happened on the palms.

• Maculopapular eruptions in the form of small flat or bulging vesicles, which were observed in 47% of cases. These rashes persisted for about a week and appeared simultaneously with other symptoms, but most often accompanied by a severe course of the disease.

• The appearance of a vascular red-blue network or signs of skin necrosis on the skin was observed in 6% of patients, mostly elderly with a severe course of the disease.

At the same time, experts note that the rash can have a different origin, and it is difficult to classify it without having the appropriate experience and knowledge.

In case of any skin symptoms, Medicover dermatologists with many years of experience and extensive experience in diagnosing various skin lesions are always ready to help you!

Skin lesions and diagnosis of COVID-19

Diagnosis of dermatological changes caused by COVID-19 consists primarily in the exclusion of other possible causes of rashes, such as allergies.

This may require a series of studies to determine if the rash is related to SARS-CoV-2 infection, or if it is a reaction of the body to certain medications, or if the infection is caused by other pathogens.

If finger pressure on purple-red skin lesions does not cause them to disappear, this is an alarm that indicates the need to seek medical attention in order to rule out infection with the SARS-CoV-2 virus.

In Medicover clinics, you can get professional advice from a dermatologist and undergo all the necessary examinations to establish an accurate diagnosis, as well as get advice on effective treatment in accordance with modern international clinical guidelines.

Coronavirus rash - when does it occur and how long does it last?

The first symptoms of COVID-19 can occur approximately 5-6 days after infection, sometimes this period is extended up to 14 days. However, a rash can be both the first symptom and the only sign of COVID-19..

Depending on the type of skin lesions and their severity, they last from several days to several weeks.

Skin rash may be accompanied by other systemic symptoms associated with COVID-19. These include:

• fever

• Permanent cough

• shortness of breath, breathing problems,

• Fatigue

• Ground

• Dizziness

• Loss of smell and taste.

rash as a manifestation of children inflammatory multisystem syndrome (PIMS) after COVID-19in children‎

Viral diseases are a common cause of skin lesions in children. A rash caused by SARS-Cov-2 may appear on a child's skin up to 2-4 weeks after infection and indicate the development of childhood inflammatory multisystem syndrome associated with SARS-CoV-2.

PIMS with multiform inflammatory syndrome in children sometimes occurs after COVID-19 infection, sometimes even after asymptomatic infection. PIMS most commonly occurs in schoolchildren around the age of 9years.

In the case of children, skin lesions caused by SARS-CoV-2 infection may appear as reddish papules, resembling other viral exanthems. Papules may appear on the face and back, and within 3-5 days they disappear spontaneously.

Any rash in children should be consulted with a pediatrician. Until an accurate diagnosis is established and the connection with COVID-19 is excluded, children should not come into contact with other people, especially the elderly, who are prone to a severe course of coronavirus infection up to death.

"Coronavirus fingers"

Skin lesions in the form of so-called "coronavirus fingers" are more often diagnosed in young people, adolescents and children. They take the form of red spots, vesicles and even ulcers, accompanied by swelling of the skin of the fingers and interdigital spaces.

COVID-19 and chickenpox - how is the rash different?

Papulo-vesicular eruptions in COVID-19 and chickenpox are very similar to each other. They differ in the age of patients and localization of skin lesions.

In SARS-CoV-2 infection, skin lesions are more common in adults with a mean age of 60 years. However, one of the main clinical features is the localization of lesions in the trunk area, the elements are diffuse in nature, they are characterized by the absence of itching.

The rash appears 3 days after the onset of symptoms of COVID-19 and spontaneously disappears after 8 days without leaving marks, while with chickenpox the rash can be biphasic and last up to 2 weeks.

Treatment of rash due to COVID-19

Rash due to SARS-CoV-2 infection does not require specific medical procedures. Clinical data show that it is enough to simply observe its course and apply symptomatic treatment if necessary. Useful antihistamines that relieve itching and swelling of the skin. Mild patients can use them at home.

In case of serious and significant skin lesions, systemic treatment with corticosteroids under medical supervision is recommended.
