- Usually normal when: Flesh-colored firm bumps arranged in a ring that are not painful, itchy, or scaly
- Call your doctor if: Ring-shaped lesions become very red, scaly, or itchy, suggesting they may actually be ringworm or another treatable condition
- Varies by age — see the age-by-age breakdown below
“Eczema is very common in babies and children. About 1 in 10 children will develop eczema, typically starting in the first few months of life.”
Thousands of parents search for this exact thing. You are not alone.
What Parents Should Know
According to AAD, NIH, AAP guidelines, granuloma annulare is a harmless skin condition that causes flesh-colored or slightly pink firm bumps arranged in a ring or arc shape. It is not ringworm and is not contagious. The cause is unknown. It typically resolves on its own within 1 to 2 years without treatment, though it may recur. At 0-3 months, granuloma annulare is very rare in infants under 6 months. Ring-shaped skin lesions at this age are more likely to be other conditions and should be evaluated by your pediatrician. It is generally considered normal when flesh-colored firm bumps arranged in a ring that are not painful, itchy, or scaly. However, you should contact your pediatrician promptly if ring-shaped lesions become very red, scaly, or itchy, suggesting they may actually be ringworm or another treatable condition.
Normal vs. Concerning
By Age
What to expect by age
0-3 months
Granuloma annulare is very rare in infants under 6 months. Ring-shaped skin lesions at this age are more likely to be other conditions and should be evaluated by your pediatrician.
3-6 months
If ring-shaped bumps appear at this age, they are more likely ringworm than granuloma annulare, but your pediatrician can help distinguish the two. Granuloma annulare bumps are smooth and firm without the scaling typical of ringworm.
6-12 months
Granuloma annulare may begin to appear. The bumps are typically on the hands, feet, elbows, or knees. They form a ring or arc of small, firm, smooth bumps without any scaling or itching. No treatment is needed as they resolve on their own.
12-24 months
Toddlers may develop granuloma annulare lesions that persist for months. While parents may worry about the appearance, the condition is benign. Treatment is usually not recommended for children because the lesions resolve spontaneously and treatments can cause more scarring than the condition itself.
What to Tell Your Pediatrician
- Describe when you first noticed granuloma annulare (ring-shaped skin bumps) in baby and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if ring-shaped bumps appear and you want confirmation of the diagnosis.
- Mention if the bumps are changing in appearance or becoming symptomatic.
- Let your doctor know if you have noticed any related concerns, such as changes in feeding, sleep, or movement patterns.
- Bring a list of any questions or observations you want to discuss at the appointment.
What Should You Do?
When to take action
- Flesh-colored firm bumps arranged in a ring that are not painful, itchy, or scaly
- Lesions that remain stable or slowly resolve over months
- Ring-shaped bumps appear and you want confirmation of the diagnosis
- The bumps are changing in appearance or becoming symptomatic
- Granuloma annulare lesions are very numerous or widespread
- Ring-shaped lesions become very red, scaly, or itchy, suggesting they may actually be ringworm or another treatable condition
- Widespread granuloma annulare covering large body areas, which may occasionally be associated with underlying conditions
What You Can Do at Home
- Keep track of when you notice granuloma annulare (ring-shaped skin bumps) in baby — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that flesh-colored firm bumps arranged in a ring that are not painful, itchy, or scaly — this is generally within the range of normal.
- At 0-3 months, focus on observation rather than intervention unless your pediatrician advises otherwise.
- Use fragrance-free, hypoallergenic products on your baby's skin. Avoid over-bathing — 2-3 baths per week is usually sufficient.
- While monitoring at home, seek immediate care if ring-shaped lesions become very red, scaly, or itchy, suggesting they may actually be ringworm or another treatable condition.
Related Conditions
Circular or Ring-Shaped Rash on Baby
A ring-shaped or circular rash on a baby can be caused by ringworm (a fungal infection), granuloma annulare, nummular eczema, or Lyme disease. Ringworm is the most common cause and is easily treated with antifungal cream. If the ring has a clear center with a raised, scaly border, ringworm is very likely. A ring-shaped rash following a tick bite needs prompt medical evaluation.
Is It Ringworm or Eczema?
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.
Raised Bumps on Baby's Skin
Raised bumps on a baby's skin have many possible causes, most of which are harmless. Common causes include keratosis pilaris (tiny rough bumps on upper arms and thighs), molluscum contagiosum (small, dome-shaped, pearl-like bumps from a viral infection), insect bites, viral rashes, and milia (tiny white bumps in newborns). The bumps' appearance - their color, size, texture, location, and whether they are itchy - helps determine the cause. Most resolve on their own or with simple treatment.

My Baby Has an Extra Nipple (Accessory Nipple)
Accessory (supernumerary) nipples are one of the most common minor congenital findings, occurring in about 1 in 18 people. They appear as small, flat, often pigmented bumps along the "milk line" — an embryonic line running from the armpit to the groin on each side. Most people mistake them for moles. Accessory nipples are almost always harmless and require no treatment. In rare cases, they may be associated with kidney abnormalities, so some pediatricians recommend a renal ultrasound if one is found, though this practice varies.
My Baby Was Born with a Raw Spot on Their Scalp (Aplasia Cutis)
Aplasia cutis congenita (ACC) is a condition where a baby is born with a small area of missing skin, most commonly on the scalp. It occurs in about 1 in 10,000 births. The affected area may look like a raw wound, an ulcer, or may have already healed into a thin, shiny scar by the time of birth. Most cases are small, isolated, and heal well with basic wound care — the area eventually forms a hairless scar. Larger defects or those associated with other findings may need more investigation, but isolated small ACC has an excellent prognosis.
New Treatments for Atopic Dermatitis (Eczema) in Children
Treatment for atopic dermatitis in children has advanced significantly in recent years. While moisturizers and topical steroids remain first-line treatments, newer options include non-steroidal topical medications (like crisaborole), biologic therapies (like dupilumab, approved for children 6 months and older), and JAK inhibitors. Most children's eczema is well-managed with basic skin care and mild topical treatments, but these newer options provide hope for moderate-to-severe cases.
