Is It Ringworm or Eczema?
The short answer
Ringworm and eczema can look similar, but ringworm typically forms a distinct ring shape with a clearing center and raised, scaly edges, while eczema tends to appear as irregular dry, red patches. Ringworm is a fungal infection (not actually a worm) that is treatable with antifungal cream, while eczema is a chronic condition managed with moisturizers and sometimes medicated creams.
By Age
What to expect by age
Ringworm is uncommon in very young infants but can occur, especially if there is a pet in the home or an infected family member. At this age, round red patches are more likely to be a form of eczema, nummular dermatitis, or a contact reaction. If you notice a round, scaly patch with a clearing center that is expanding outward, have your pediatrician examine it. A simple skin scraping test can distinguish ringworm from eczema.
As babies become more mobile and interact with the environment, their exposure to fungi increases. Ringworm on the body (tinea corporis) presents as one or more circular, red, scaly patches with raised borders and a clearer center. Eczema at this age usually appears in skin creases and is itchier and drier looking. A key difference is that ringworm patches tend to expand outward over days, while eczema patches stay in the same general areas.
Toddlers in daycare or who have pets are more commonly exposed to ringworm. It can appear on the scalp (tinea capitis), causing a scaly bald patch, or on the body. Scalp ringworm is especially common in toddlers and requires oral antifungal medication, not just cream. Eczema at this age tends to follow a chronic waxing and waning pattern in predictable locations like elbows and knees, whereas ringworm appears as a new isolated patch.
At this age, children can contract ringworm from playmates, shared surfaces, or animals. If your toddler develops a new ring-shaped lesion, avoid applying eczema creams containing steroids before getting a diagnosis, as steroid cream can make ringworm worse and harder to recognize (a condition called tinea incognito). Your pediatrician can often diagnose ringworm visually or with a simple skin culture.
What Should You Do?
When to take action
- A single small, round, mildly scaly patch that is not spreading rapidly or causing significant discomfort
- Dry patches in typical eczema locations (cheeks, elbows, knees) that improve with moisturizer
- A ring-shaped patch that responds to over-the-counter antifungal cream within 1-2 weeks
- A circular rash is expanding, not improving with moisturizer, or you are unsure whether it is ringworm or eczema
- Your child has a scaly, bald patch on the scalp, which may be scalp ringworm requiring oral treatment
- The rash has been present for more than 2 weeks without improvement despite treatment
- The affected area is becoming very swollen, boggy, tender, or oozing pus, which may indicate a kerion (an inflamed fungal abscess on the scalp) or secondary bacterial infection
- Your child has a widespread rash with fever and seems unwell, which could indicate a more serious condition than either ringworm or eczema

Related Skin Concerns
Baby Acne (Neonatal Acne)
Baby acne is a very common, harmless condition that appears as small red or white bumps on your newborn's face, usually around 2-4 weeks of age. It is caused by maternal hormones still circulating in your baby's system and clears up on its own within a few weeks to months without any treatment.
Baby Blister on Lip from Nursing
A nursing blister (also called a suck callus) is a small, painless blister or thickened patch on your baby's upper lip caused by the friction of latching during breastfeeding or bottle feeding. It is completely harmless, does not hurt your baby, and does not need any treatment. These are very common in newborns and typically come and go in the early weeks.
Baby Chin Rash from Drooling
Drool rash is extremely common and appears as red, irritated, or slightly bumpy skin on the chin, cheeks, neck, and chest where drool sits. It is caused by the constant moisture and digestive enzymes in saliva irritating the skin. Keeping the area dry and applying a barrier like petroleum jelly before drool exposure is the most effective treatment.
Baby Dry Patches on Cheeks
Dry patches on your baby's cheeks are very common, especially during cold or dry weather. Baby skin is much thinner and more sensitive than adult skin and loses moisture easily. In most cases, regular application of a gentle, fragrance-free moisturizer is all that is needed. If patches are red, rough, or itchy, mild eczema may be the cause.
Baby Ingrown Toenail
Ingrown toenails are fairly common in babies and toddlers, especially on the big toe. Baby toenails are soft and can easily curve into the surrounding skin. Most mild cases improve with warm soaks and gentle care. If the toe becomes very red, swollen, or shows signs of infection, your pediatrician can help with treatment.
Baby Nail Peeling or Splitting
Peeling or splitting nails in babies are very common and usually harmless. Baby nails are extremely thin and soft, making them prone to peeling, especially from normal wear and moisture exposure. This typically improves as your child grows and their nails become stronger. Keep nails trimmed short and moisturize the nail area gently.
