Images of Tinea Corporis (Ringworm of Body)
Tinea infections are commonly called ringworm because some may form a ring-like pattern on affected areas of the body. Tinea corporis, also known as ringworm of the body, tinea circinata, or simply as ringworm, is a surface (superficial) fungal infection of the skin. Ringworm may be passed to humans by direct contact with infected people, infected animals (such as kittens or puppies), contaminated objects (such as towels or locker room floors), or the soil.
There are several kinds of ringworm, including:
- Majocchi's granuloma, a deeper fungal infection of skin, hair, and hair follicles. It is most common in women who shave their legs.
- Tinea corporis gladiatorum, a special name given to ringworm spread by skin-to-skin contact between wrestlers.
- Tinea imbricata, a form of ringworm seen in Central and South America, Asia, and the South Pacific.
Who's at risk?
Ringworm may occur in people of all ages, of all races, and of both sexes.
Ringworm is most commonly seen in children. Other people who are more likely to develop ringworm include:
- Women of child-bearing age who come into contact with infected children.
- People who have another tinea infection elsewhere on their bodies: tinea capitis (scalp), tinea faciei (face), tinea barbae (beard area), tinea cruris (groin), tinea pedis (feet), or tinea unguium (fingernails or toenails).
- Athletes, especially those involved in contact sports.
- People in frequent contact with animals, especially cats, dogs, horses, and cattle.
- People with weakened immune systems.
- People who sweat heavily.
- People who live in warmer, more humid climates.
Signs and Symptoms
The most common locations for ringworm include:
- Trunk (chest, abdomen, back)
Ringworm may cause itching or burning, especially in people with weak immune systems.
If you suspect that your child has ringworm, you might try one of the following over-the-counter antifungal creams or lotions:
Since people often have tinea infections on more than one body part, examine your child for other ringworm infections, such as on the face (tinea faciei), in the groin (tinea cruris, jock itch), or on the feet (tinea pedis, athlete's foot).
Have any household pets evaluated by a veterinarian to make sure that they do not have a dermatophyte infection. If the veterinarian discovers an infection, be sure to have the animal treated.
When to Seek Medical Care
If large areas of the body are affected, or if the lesions do not improve after 1–2 weeks of applying over-the-counter antifungal creams, see your child's doctor for an evaluation.
Treatments Your Physician May Prescribe
In order to confirm the diagnosis of ringworm, your child's physician might scrape some surface skin material (scales) onto a slide and examine them under a microscope. This procedure, called a KOH (potassium hydroxide) preparation, allows the doctor to look for tell-tale signs of fungal infection.
Once the diagnosis of ringworm has been confirmed, the physician will probably start treatment with an antifungal medication. Most infections can be treated with topical creams and lotions, including:
