Eczema vs Ringworm: Key Differences
Content reviewed against published AAP, AAD, CDC guidelines
Last reviewed:
Eczema and ringworm can both cause itchy, red, scaly patches on the skin. However, eczema is a chronic inflammatory condition while ringworm is a contagious fungal infection requiring antifungal treatment.
Key takeaways
- Ringworm has a distinctive ring shape with clear center; eczema patches are irregular
- Ringworm is contagious; eczema is never contagious
- Eczema is chronic and recurring; ringworm clears completely with antifungal treatment
- Eczema occurs in typical locations (creases, cheeks); ringworm can appear anywhere
: Cause
Eczema (Atopic Dermatitis): Chronic immune/skin barrier condition (genetic + environmental triggers)
Ringworm (Tinea): Fungal infection (dermatophytes)
: Appearance
Eczema (Atopic Dermatitis): Dry, rough, scaly patches; may weep or crust when flaring
Ringworm (Tinea): Ring-shaped patch with raised, scaly border and clearer center
: Shape
Eczema (Atopic Dermatitis): Irregular, poorly defined edges
Ringworm (Tinea): Circular or oval with distinct ring pattern
: Location
Eczema (Atopic Dermatitis): Creases (elbows, knees, neck); cheeks in babies
Ringworm (Tinea): Anywhere on body; scalp, trunk, and limbs common
: Number of patches
Eczema (Atopic Dermatitis): Usually multiple patches, often symmetrical
Ringworm (Tinea): Often starts as a single patch, may slowly spread
: Contagious
Eczema (Atopic Dermatitis): No — never contagious
Ringworm (Tinea): Yes — spreads via skin contact, shared items, or animals
: Itch
Eczema (Atopic Dermatitis): Intense, widespread itching (especially at night)
Ringworm (Tinea): Mildly to moderately itchy
: Treatment
Eczema (Atopic Dermatitis): Moisturizers, topical steroids, avoiding triggers
Ringworm (Tinea): Antifungal cream (clotrimazole, terbinafine) for 2-4 weeks
: Age of onset
Eczema (Atopic Dermatitis): Usually starts in infancy (before age 5)
Ringworm (Tinea): Common in school-age children
| Eczema (Atopic Dermatitis) | Ringworm (Tinea) | |
|---|---|---|
| Cause | Chronic immune/skin barrier condition (genetic + environmental triggers) | Fungal infection (dermatophytes) |
| Appearance | Dry, rough, scaly patches; may weep or crust when flaring | Ring-shaped patch with raised, scaly border and clearer center |
| Shape | Irregular, poorly defined edges | Circular or oval with distinct ring pattern |
| Location | Creases (elbows, knees, neck); cheeks in babies | Anywhere on body; scalp, trunk, and limbs common |
| Number of patches | Usually multiple patches, often symmetrical | Often starts as a single patch, may slowly spread |
| Contagious | No — never contagious | Yes — spreads via skin contact, shared items, or animals |
| Itch | Intense, widespread itching (especially at night) | Mildly to moderately itchy |
| Treatment | Moisturizers, topical steroids, avoiding triggers | Antifungal cream (clotrimazole, terbinafine) for 2-4 weeks |
| Age of onset | Usually starts in infancy (before age 5) | Common in school-age children |
When to Worry
- Ring-shaped rash spreading despite moisturizer use (likely ringworm, not eczema — needs antifungal)
- Signs of secondary bacterial infection: honey-colored crusting, pus, increasing redness or warmth
- Rash on the scalp with hair loss (scalp ringworm needs oral antifungal)
- Widespread rash that is not responding to treatment within 2 weeks
- Fever accompanying the skin rash

Bottom line
Both Eczema (Atopic Dermatitis) and Ringworm (Tinea) are common in young children. The key differences in symptoms can help you identify what your child may have, but when in doubt, consult your pediatrician.
