Overview
Tinea corporis is a skin infection due to fungi. It is also called ringworm of the body.

What are the symptoms of Tinea corporis?
Symptoms may include itching.

The rash begins as a small area of red, raised spots and pimples. The rash slowly becomes ring-shaped, with a red-colored, raised border and a clearer center. The border may look scaly.

The rash may occur on the arms, legs, face, or other exposed body areas.

What causes Tinea corporis?
Tinea corporis is a common skin disorder among children. However, it may occur in people of all ages. It is caused by mold-like fungi called dermatophytes.

Fungi thrive in warm, moist areas. The following raise your risk for a fungal infection:


 * Long-term wetness of the skin (such as from sweating)
 * Minor skin and nail injuries
 * Poor hygiene

Who is at highest risk?
Tinea corporis can spread easily to other people. You can catch the condition if you come into direct contact with an area of ringworm on someone's body, or if you touch contaminated items such as:


 * Clothing
 * Combs
 * Pool surfaces
 * Shower floors and walls

The fungi can also be spread by pets (cats are common carriers).

Diagnosis
The health care provider can often diagnose tinea corporis by how the skin looks.

In some cases, the following tests may be done:

Looking at a skin scraping of the rash under the microscope using a KOH (potassium hydroxide) test Skin lesion biopsy

When to seek urgent medical care?
Call for an appointment with your health care provider if ringworm does not improve with self-care.

Treatment options
Keep the skin clean and dry.

You can buy antifungal cream without a prescription, or your health care provider may prescribe it.


 * Wash and dry the area first.
 * Apply the cream, beginning just outside the area of the rash and moving toward the center. Be sure to wash and dry your hands afterward.
 * Use the cream twice a day for 7 to 10 days.
 * Do not use a bandage over ringworm.
 * Creams that contain miconazole, clotrimazole, ketoconazole, terbenifine, or oxiconazole are often effective in controlling ringworm.

Once treatment has started, a child can return to school.

To prevent the infection from spreading:

Your health care provider will prescribe medicine taken by mouth to treat ringworm that:
 * Wash all towels in warm, soapy water and then dry them.
 * Use a new towel and washcloth every time.
 * Clean sinks, bathtubs, and bathroom floors well after using.
 * Wear clean clothes every day and do not share clothes

Antibiotics may be needed to treat secondary bacterial infections.
 * Is severe or covers a large area of your body
 * Passes deeper into the skin to the hair follicle, such as in a beard.

Infected pets should also be treated.
