Tinea versicolor, also called pityriasis versicolor, is a common fungal skin infection caused by yeast on the skin. 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 occurs mostly in adolescence and early adulthood due to oily skin, but can occur at any time.
Usually, the only symptom of tinea versicolor is white, pink, or light brown patches. Patches may scale slightly, but rarely itch or hurt. Other common characteristics of the rash include:
The symptoms of tinea versicolor may resemble other skin conditions. Always consult your child's doctor for diagnosis.
Tinea versicolor is usually diagnosed based on a medical history and physical examination of your child. The patches seen with this condition are unique, and usually allow the diagnosis to be made on physical examination. In addition, your child's doctor may use an ultraviolet light, called a Woods Lamp, to see the patches more clearly. Also, your child's doctor may do skin scrapings of the lesions to help confirm the diagnosis.
Treatment usually includes the use of an antifungal or dandruff shampoo on the skin as prescribed by your child's doctor. Tinea versicolor usually recurs, requiring additional treatments. Your child's doctor may also prescribe topical creams or oral antifungal medications.
It is also important to know that improvement in the skin may be only temporary, and a recurrence of the condition is possible. Your child's doctor may also recommend using the shampoo monthly to help prevent recurrences. The treatment will not bring the normal color back to the skin immediately. This will occur naturally and may take several months.
