What is Tinea Versicolor?
Tinea Versicolor is a common fungal skin infection caused by yeast on the skin. It is also called Pityriasis Versicolor. It is characterized by lighter or darker patches on the skin. Patches are most often found on the chest or back and prevent the skin from tanning evenly. It happens mostly in adolescence and early adulthood due to oily skin, but it can happen at any time.
What are the Symptoms of Tinea Versicolor?
Usually, the only Symptom of Tinea Versicolor is the white or light brown patches with well-defined borders. Patches may scale slightly, but rarely itch or hurt. Other common characteristics of the rash include the following:
- White, pink, or reddish-brown patches
- Infection only on the top layers of the skin
- The rash usually happens on the trunk
- The rash does not usually happen on the face
- Patches worsen in the heat, humidity, or if you are on steroid therapy or have a weakened immune system
- Patches are most noticeable in the summer
- Affected areas do not darken in the sun
The Symptoms of Tinea Versicolor may resemble other skin conditions. Always talk with your healthcare provider for a diagnosis.
How Tinea Versicolor Is Diagnosed?
Tinea versicolor is usually diagnosed based on a medical history and physical exam. The patches seen with this condition are unique and usually allow the diagnosis to be made on a physical exam. In addition, your healthcare provider may use ultraviolet light, called a Woods Lamp, to see the patches more clearly. Also, your Health Care Provider may do skin scrapings of the lesions to help confirm the diagnosis under the microscope or in the lab.
Treatment for Tinea Versicolor
Specific Treatment for Tinea Versicolor will be discussed with you by your healthcare provider based on:
- Your age, overall health, and medical history
- The extent of the condition
- Your tolerance for specific medicines, procedures, or therapies
- Expectations for the course of the condition
- Your opinion or preference
Treatment usually includes the use of an antifungal or dandruff shampoo on the skin, as prescribed by your healthcare provider. Tinea versicolor usually happens again, needing additional treatments. Your healthcare provider may also prescribe topical creams or oral antifungal medicines. It is also important to know that improvement in the skin may be only temporary, and the condition can happen again. Your healthcare provider may also recommend using the shampoo monthly to help prevent it from happening again. The treatment will not bring the normal color back to the skin immediately. This will happen naturally and may take several months. People with this condition should try to avoid excessive heat or sweating.
