Granuloma Annulare (Ring-Shaped Skin Bumps) in Baby
The short answer
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.
Thousands of parents search for this exact thing. You are not alone.
By Age
What to expect by age
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.
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.
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.
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 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

Related Skin Concerns
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.
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.
