Tinea versicolor is a common fungal skin infection 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, but it can occur at any time.
Usually the only symptom of tinea versicolor is the white or light brown patches. Patches may scale slightly, but rarely itch or hurt. Other common characteristics of the rash include:
- white, pink, or brown patches
- infection only on the top layers of the skin
- the rash usually occurs on the trunk
- the rash does not usually occur on the face
- patches worsen in the heat, humidity, or if your child is on steroid therapy or has a weakened immune system
- patches are most noticeable in the summer
The symptoms of tinea versicolor may resemble other skin conditions. Always consult your child's physician 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 physician may use an ultraviolet light to see the patches more clearly. Also, your child's physician may do skin scrapings of the lesions to help confirm the diagnosis.
Treatment usually includes the use of dandruff shampoo on the skin as prescribed by your child's physician. The shampoo is left on the skin overnight and washed off in the morning. To be effective, the shampoo treatment may be required for several nights. Tinea versicolor usually recurs, requiring additional treatments. Your child's physician may also prescribe topical creams or oral antifungal medications.
It is also important to know that improvement in the skin may only be temporary, and a recurrence of the condition is possible. Your child's physician 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.
