What’s the difference between nummular eczema and ringworm?
Once your dermatologist diagnoses and treats the rash, you may get better within 7-10 days. Nummular eczema takes longer to heal than ringworm. Sometimes, it may take up to a year, and it may return if not cured completely. In extreme cases, it may scar or cause the affected skin to become darker.
What is nummular eczema?
- Coin-shaped patches on your legs, arms, back, buttocks, foot, and hands.
- Extreme itching and burning lesions.
- Oozing and crusted scaly lesions.
The causes of this rash are not clear. However, you may get this eczema if you have
Skin reaction to another type of eczema:
- Atopic dermatitis (familial condition inflammation of the skin, especially in children).
- Stasis dermatitis (inflammation of the leg skin due to fluid build-up).
- Contact dermatitis (inflammation of the skin after contact with certain substances).
What is ringworm?
Ringworm is a common skin infection also known as dermatophytosis, dermatophyte infection, or tinea corporis. It is not a worm infection, but it is caused by fungi (mold) that live in the dead tissues of our skin. It is so-called because the rash has a ring-like shape and spreads in a ring-like manner. Ringworm is highly contagious.
You may get red, itchy, and scaly patches with sharp edges. These are red at the edges and have a normal looking center. Sometimes, the rash may blister and ooze. Scalp infection of ringworm is very common in children. It mainly spreads through skin-to-skin contact by sharing personal objects or even through an infected animal.
It can be commonly misdiagnosed with nummular eczema, tick-borne disease (Lyme disease), or spider bite. Therefore, consult your dermatologist if you get ring-like patches. Ringworm may develop at the following sites on the body:
- On your scalp
- In between your toes (athlete’s foot/tinea pedis)
- In between your skin folds of the groin region (jock’s itch/tinea cruris)
- Over the cheeks (barber’s itch)
- On your face (tinea faciei)
- On your hands or even nails
How can you prevent these skin infections?
The best way to prevent is to:
- Keep your skin dry and clean.
- Do not share personal items such as towels, clothes, soaps, and creams.
- Change your undergarments at least once a day.
- Wash your hands after playing with pets, especially if your pet has ringworm.
- Do not wear certain metal or dyed substances if you have hypersensitive skin.
