Once we identify nummular eczema and treat it appropriately, most people are significantly better within seven to 10 days, and, for patients who dont have another type of eczema, it often never comes back, according to Dr. Peter Lio, founding director of the Chicago Integrative Eczema Center.

What Are The Symptoms Of Nummular Eczema

The most common and noticeable symptom of nummular eczema is a patch of coin-shaped lesions on the body. The lesions frequently develop on the arms or legs, but they may eventually spread to the torso and hands. They may be brown, pink, or red.

Other symptoms may include:

  • lesions that are very itchy and burn
  • lesions that ooze fluid and eventually crust over
  • red, scaly, or inflamed skin around the lesions

Signs of eczema clearing or new flare-ups:

  • Flatter spots are visible.
  • Skin discoloration is present in the area where the spot flattens. In dark skin, this discoloration is known as postinflammatory hypopigmentation and may last for several months.
  • A new flare-up may show up as a large, raised patch on top of an old, healing spot instead of a coin-shaped lesion.

What Should I Know About Nummular Eczema Treatment

The first step in treating nummular eczema is getting a proper diagnosis from a board-certified dermatologist if at all possible, according to Dr. Makhzoumi. We are trained to know the difference between all these red, round, scaly things, she says. Further, your dermatologist can take a small scraping from the top of the rash and check it under the microscope to see if it is caused by a fungus to rule out ringworm.

About 25% of people with nummular eczema also have allergic contact dermatitis, meaning their skin develops an allergic reaction to a substance. If you can, getting a skin patch test can help identify if youre allergic to anything in particular, so you can avoid those triggers as much as possible. During an office visit, your doctor will place small amounts of potential allergens on your skin that are covered with patches, according to the AAD. Roughly two days later, youll head back to your doctor so they can inspect your skin for reactions, such as skin rashes. You may need to have a follow-up appointment several days later so your doctor can take another look at your skin.

After your doctor diagnoses you with nummular eczema, they may discuss the following treatments:

Alternatively, your doctor may recommend a topical calcineurin inhibitor like tacrolimus or pimecrolimus as an alternative or in addition to steroids. These medicines work by dialing down the overactive immune response that causes eczema flares.

How Do Doctors Tell Whether Its Eczema Or Ringworm

Doctors diagnose eczema in large part by looking at it and by eliminating other possible causes of your symptoms. They might ask if anything seems to trigger an outbreak and whether you have a history of eczema in your family. They also may test your skin for allergic reactions or draw some blood to look for alternate causes.

Ringworm is one of the conditions they may try to eliminate. Your doctor might be able to tell simply by looking at your skin you have ringworm and not eczema. If theyâre still unsure, they might scrape some skin cells from the area to look at under a microscope.

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.

You can get ringworm by touching surfaces, objects, people, or animals that have ringworm.

How Do Doctors Diagnose Them

A doctor will diagnose nummular eczema or ringworm by examining the skin and asking about signs and symptoms. They may ask when the rash first appeared, what makes it better or worse, and if the person has already tried any treatments.

Symptoms Of Discoid Eczema

Discoid eczema causes distinctive circular or oval patches of eczema. It can affect any part of the body, although it does not usually affect the face or scalp.

The first sign of discoid eczema is usually a group of small spots or bumps on the skin. These then quickly join up to form larger patches that can range from a few millimetres to several centimetres in size.

On lighter skin these patches will be pink or red. On darker skin these patches can be a dark brown or they can be paler than the skin around them.

Initially, these patches are often swollen, blistered and ooze fluid. They also tend to be very itchy, particularly at night.

Over time, the patches may become dry, crusty, cracked and flaky. The centre of the patch also sometimes clears, leaving a ring of discoloured skin that can be mistaken for ringworm.

You may just have 1 patch of discoid eczema, but most people get several patches. The skin between the patches is often dry.

Patches of discoid eczema can sometimes become infected. Signs of an infection can include:

  • the patches oozing a lot of fluid
  • a yellow crust developing over the patches
  • the skin around the patches becoming hot, swollen and tender or painful

Causes Of Discoid Eczema

The cause of discoid eczema is unknown, although it may happen as a result of having particularly dry skin.

When your skin is very dry it cannot provide an effective barrier against substances that come into contact with it. This could allow a previously harmless substance, such as soap, to irritate your skin.

It’s important to look carefully at all the chemicals in cosmetics and toiletries that may have come into contact with your skin. Contact dermatitis, a type of eczema caused by coming into contact with a particular irritant, may have a role in discoid eczema.

Some people with discoid eczema also have a history of atopic eczema, which often happens in people who are prone to asthma and hay fever. However, unlike atopic eczema, discoid eczema does not seem to run in families.

Symptoms Of Ringworm Vs Nummular Eczema

While both conditions can present as itchy, red, and scaly there are some distinct differences in each condition including longevity and transmission.

Ringworm Symptoms

  • Rash that is round and has a defined edge
  • Itching, which may be severe
  • May have small black dots in the center of the rash
  • Can spread to other parts of the body very easily
  • Rash that is red and dry, can be scaly and may look like the skin has been burned
  • Itching, which is often not severe unless caused by an allergic reaction or other cause of eczema flare-ups
  • May not have a round shape but can occur in different areas on one person at once if they are exposed to something that causes them to break out
  • Ringworm can spread to other parts of the body and is contagious to others, especially with skin-to-skin contact.

Eczema symptoms Include:

  • Itching, which may be severe, especially at night
  • Red to brownish-gray patches, especially on the hands, feet, ankles, wrists, neck, upper chest, eyelids, inside the bend of the elbows and knees, and in infants, the face and scalp
  • Small, raised bumps, which may leak fluid and crust over when scratched
  • Thickened, cracked, scaly skin
  • Raw, sensitive, swollen skin from scratching

Eczema is not contagious and typically lasts longer than ringworm. Many individuals have chronic eczema, which means it can last for years or a lifetime. It is common for eczema to flare up in intensity. This difference is one of the most crucial in both identifying and treating eczema and ringworm
