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.
This is one of the most common questions parents ask. Searching for answers means you care.
By Age
What to expect by age
0-6 months
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.
6-12 months
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.
1-2 years
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.
2-3 years
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

Baby Acne vs Eczema: How to Tell the Difference
Baby acne and eczema can both cause facial rashes, but they look and feel different. Baby acne appears as small red or white bumps, similar to teenage acne, usually on the cheeks, nose, and forehead. Eczema causes dry, rough, red, itchy patches. Baby acne resolves on its own by 3 to 4 months, while eczema may need ongoing management.
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.
Alopecia Areata in Babies
Alopecia areata is an autoimmune condition where the immune system attacks hair follicles, causing round, smooth patches of hair loss. While uncommon in babies, it can occur at any age. The condition is not painful or contagious. Many children experience spontaneous hair regrowth, though it may take months. Your pediatrician or dermatologist can confirm the diagnosis.
Athlete's Foot in Toddlers
True athlete's foot (tinea pedis) is actually uncommon in babies and toddlers but can occasionally occur in children who walk barefoot in moist communal areas. Peeling or dry skin on toddler feet is more often caused by juvenile plantar dermatosis (dry, cracked skin from friction) or eczema rather than a fungal infection.
Bed Bug Bites on Baby
Bed bug bites on babies appear as small, red, itchy welts often in lines or clusters, typically noticed in the morning. Bed bugs are not known to transmit diseases, but the bites can cause significant itching and discomfort. Treatment focuses on managing itch with cool compresses and anti-itch cream while eliminating the bed bug infestation from the home.
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.
