Overview

Tinea versicolor is a fungal skin infection. It’s caused by yeast on the skin. It occurs most often in teens and young adults. But it can happen at any age.

This condition causes lighter or darker patches on your child’s skin. These patches are often on your child’s chest or back. They stop the skin from tanning evenly.

Causes

Yeast normally lives on the skin in small amounts. Tinea versicolor occurs when yeast expands and increases greatly in number (overgrows).

Risk Factors

The following can increase your child’s risk for tinea versicolor:

  • Living in a hot, humid climate
  • Having moist and oily skin
  • Having a weakened immune system

Symptoms

Often, the only symptom of this condition is white, pink, or light brown patches on your child’s skin. The patches may have very fine scale-like flakes. It normally doesn’t itch or hurt.

Here are other aspects of the rash:

  • An infection is only on the top layers of the skin.
  • The rash is on your child’s chest or back.
  • The rash isn’t usually on the face.
  • Patches get worse in the heat or humidity.
  • You notice the patches more in the summer.
  • Patches get worse if your child takes steroid medicines or has a weakened immune system.

The symptoms of this condition may look like symptoms of other health problems. Make sure your child sees their healthcare provider for a diagnosis.

Diagnosis

Your child’s healthcare provider will ask about your child’s health history. They will also give your child an exam. The patches caused by this condition are unique. Healthcare providers are often able to make the diagnosis through an exam.

Your child’s healthcare provider may use an ultraviolet light, called a Wood's lamp, to see the patches more clearly. Also the provider may do skin scrapings of the lesions to examine under the microscope. This can help confirm the diagnosis.

Treatment

Your child’s healthcare provider may advise using a shampoo that contains selenium sulfide. This shampoo is available over the counter. If this treatment doesn’t work, the provider may prescribe an antifungal or dandruff shampoo. Your child will apply the shampoo to their affected skin. The provider may also prescribe topical antifungal creams or oral antifungal medicines.

Your child’s skin may only get better for a short time. Then the condition may happen again. The provider may tell your child to use the shampoo each month to keep tinea versicolor from coming back.

The treatment won't make your child’s skin return to its normal color right away. This may take a few weeks or months. It’s important not to tan and to protect skin from the sun.

When to Call a Healthcare Provider

If your child’s treatment isn’t working, call their healthcare provider. They may suggest other treatments.
