How To Tell The Difference Between Eczema And Ringworm

Get A Diagnosis Before Trying Topical Corticosteroids At Home

Is it Eczema or Ringworm?

While topical corticosteroids are effective at treating eczema, they can actually make ringworm worse. Steroids may improve the itching and swelling, but they cannot kill the fungal infection. This may lead to the infection spreading and weakening your skins defenses. Using steroid cream can also cause ringworm to change its appearance. This makes it harder for your primary care doctor to diagnose it and provide the right treatment.

HSV can be recurrent and some people get repeated blisters frequently over the same area. Other viral infections like hand foot and mouth disease can also present with small blisters and ulcers on the lips, and this can be scattered throughout the lips and buccal mucosa. In HFMD, the blisters are also seen on the hands and feet and you may have other systemic signs like fever.

How Do You Know If You Have Ringworm

Ringworm often creates a ring-shaped rash with a raised, scaly border that snakes its way around the edge like a worm. Some experts believe that the appearance may be where it got its name.

The rash is typically itchy and can cause discomfort. A person should talk with their doctor about getting a diagnosis if they suspect ringworm.

Difference Between Nummular Eczema and Ringworm

Seborrheic dermatitis may closely resemble tinea or psoriasis, especially in the groin. Distribution is helpful in distinguishing seborrheic dermatitis from tinea. When seborrheic dermatitis is present on the face, lesions are remarkably symmetric, mostly affecting the forehead, eyebrows, and retroauricular areas.36 When present in large folds, seborrheic dermatitis tends to be centered along the crease, whereas tinea is less often as symmetric.36 In addition, patches and plaques of seborrheic dermatitis typically are more numerous and appear greasier than lesions of tinea. Plaques of psoriasis are associated with a heavier scale that, unlike seborrheic dermatitis, bleeds when removed.32

Treatment consists of imidazoles, mainly ketoconazole, as a shampoo when present on the scalp or cream when present on the face and body.36 Topical steroids work quickly and are effective but should be limited because of the risk of steroid rosacea.32 Once cleared, daily maintenance therapy is important to prevent relapse.

Oral Or Injectable Medications

For moderate to severe cases of psoriasis where other treatments dont work, your doctor may prescribe an oral or injected medication. These medications reduce inflammation and slow or stop skin cell growth by altering your immune system.

Options include oral medications like methotrexate, cyclosporine, acitretin, and Otezla or injectable biologics like Humira, among others.

Some non-biologics that your doctor may prescribe are:

  • methotrexate
  • etanercept
  • infliximab

As with any treatment, there are possible side effects you should be aware of. Its important to talk to a doctor to determine the best course of treatment for you. Theyll also keep an eye on your overall health for any signs of potentially dangerous side effects.

How Do Symptoms Of Eczema And Ringworm Compare

Both eczema and ringworm tend to inflame and redden the skin and can make it dry, swollen, crusty, and itchy. In addition, both can happen almost anywhere on the body, head to toe.

One symptom that sometimes helps tell the difference is that ringworm often produces a scaly, ring-shaped rash, typically on the trunk, arms, or legs. But nummular, or âdiscoid,â eczema also produces a round, scaly rash that can look like ringworm.

If you think you have ringworm, but over-the-counter remedies fail to work, it may be time to see your doctor. You may have eczema, psoriasis, or some other skin condition. Only your doctor can tell for sure the source of your symptoms.

Specific Symptoms Of Psoriasis

While psoriasis doesnt have symptoms that are as clear cut as those of ringworm, there are a few other ways you might be able to tell that its psoriasis and not something else.

First, if the symptoms are recurring and lack that ring-like feature, it may be psoriasis. Since psoriasis is a chronic condition, it doesnt really go away over a few days with treatment like ringworm will.

Second, about 30% of people with psoriasis develop psoriatic arthritis, a type of arthritis closely associated with psoriasis.

In many cases, ringworm can be treated with creams, lotions, or powders containing antifungals such as clotrimazole or miconazole, and many of those treatments are available over the counter. If the infection does not respond well to that treatment, your healthcare provider may prescribe a cream containing a higher concentration of antifungal medication. Sometimes, oral antifungals, such as griseofulvin, fluconazole, terbinafine, or itraconazole, are necessary to clear up the infection. Thats the case when the lesion is recurrent, chronic, or doesnt get better after using prescription-strength topical antifungal products .

In addition to antifungals, your healthcare provider might recommend hygiene measures that make the growing conditions for the fungus unfavorable. These include wearing well-ventilated clothing, avoiding bandaging the area, and changing damp or wet clothes frequently.

Since ringworm is contagious, it is essential to prevent reinfecting yourself as well as passing the fungus on to others . According to the American Academy of Dermatology , a person with ringworm should avoid touching the rash and wash their hands frequently. Bedding, as well as clothing, should be washed frequently in detergent and hot water. You should wear shower shoes at the gym or pool locker rooms, and a shower should be taken after a workout, followed by changing into clean clothes .

Diagnosing Nummular Eczema And Ringworm

Youll need to see your doctor for a diagnosis of either condition.

Its best to have nummular eczema diagnosed by a dermatologist. A doctor specializing in skin conditions or even your primary care doctor can help determine a treatment plan and rule out other conditions.

Nummular eczema is diagnosed with a physical exam. A doctor can usually make a diagnosis by looking at the skin. Nummular eczema is most prominent in these areas of the body:

  • legs
  • arms
  • torso

If you have open sores within any of the rashes, your doctor may take a sample to see if you have an infection. This is especially important if your symptoms look like ringworm.

A sample can help them determine if you have a staph infection from eczema, or if its a fungal infection related to ringworm.

Red, circular rashes on the skin are a telltale sign of ringworm, but your doctor may also test a sample to confirm. Theyll look for signs of a fungal infection. If the fungal test is negative, then you dont have ringworm.

Once you have an accurate diagnosis, your doctor can explain treatment options.

Is It Ringworm Or Eczema

While there are some similarities between the two conditions, there are many differences, too.

Ringworm Despite the name, ringworm isnt caused by a worm. Its a type of fungus, the same type that causes athletes foot and jock itch, in fact. The name comes from the appearance of the condition, a red ring around a white center of scaly skin. Ringworm usually isnt painful but it can be extremely itchy and uncomfortable.

Eczema While doctors arent sure exactly what causes eczema, they do know its not caused by any kind of fungus. Its thought to be a combination of dry, irritable skin and some sort of disorder or malfunction of the immune system. Eczema causes scaly patches of skin, but unlike ringworm, these arent round or ring-like in appearance. Patches of eczema are red or brownish in color and may ooze or bleed, especially if you scratch the area a lot. Eczema is not just itchy, it can be pretty painful, as well.

Ringworm has a pretty distinctive appearance. Youre not likely to mistake it for something else.

When trying to determine if youve got ringworm or eczema, one other factor to consider is the fact that ringworm is contagious. Eczema is not. If other members of your household are suffering from the same skin problem, its probably not eczema.

    Whats The Difference Between Psoriasis And Ringworm

    The biggest difference between psoriasis and ringworm, says Dr. McGregor, is the origins of each. Psoriasis is an autoimmune condition, while ringworm is a fungal infection. While a persons autoimmune issues trigger psoriasis, you can acquire the ringworm fungus in a number of different ways, he adds, from soil, other humans or even pets.

    Additionally, psoriasis is a chronic condition, meaning it never goes away. Ringworm, conversely, will go away with treatment since its simply an infection.

    When To Seek Medical Advice

    See a pharmacist or GP if you think you may have discoid eczema. They can recommend a suitable treatment.

    You should also seek medical advice if you think your skin may be infected. You may need to use an antibiotic cream or, in severe cases, take antibiotics as a tablet or capsule.

    A GP should be able to make a diagnosis just by examining the affected areas of skin. In some cases they may also ask questions or arrange some tests to rule out other conditions.

    A GP may refer you to a doctor who specialises in skin conditions if they’re unsure of the diagnosis or if you need a patch test.

    Nummular eczema can be mistaken for a common infection that appears as a circular, itchy rash: tinea corporis, which is known as ringworm. It tends to present, as the name suggests, like a ring, Dr. Makhzoumi says. The two skin conditions are almost indistinguishable except for one subtle clue. Ringworm bumps are typically flat and have scaling on the border whereas an entire nummular eczema patch can be raised and scaly, Dr. Silverberg says. Further, the center of a ringworm patch may look like your typical skin color rather than red or brown, Dr. Silverberg says.

    Ringworm, which can be spread from person to person , is caused by more than 40 species of fungi, including Trichophyton, Microsporum, and Epidermophyton, according to the Centers for Disease Control and Prevention . You can get ringworm by touching surfaces, objects, people, or animals that have ringworm. If you regularly shower at the gym and people you have been in contact with suddenly develop itchy, flat circles with scaly borders, that could be a sign that your skin rash is possibly pointing to ringworm.

    • The groin and axillary regions are spared in eczema but are not spared in certain ringworm infections .
