- Pityriasis alba is the appearance of white, scaly patches that range from 1 to 2 inches in diameter and appear in the neck and arms of children. Tinea versicolor is caused by a fungus that lives on the skin and causes uneven coloration.
- Most common in adolescents and young adults between the ages of 15 to 30 years old, Tinea versicolor can happen at any age, toddlers included.
- A pediatrician may scrape a small sample of skin to confirm the diagnosis. This procedure is painless and involves taking a specimen from one of the discolored patches.
- Topical anti-fungal medicine treats Tinea versicolor. A moisturizer is used along with sunscreen to prevent the darkening of spots in treating Pityriasis alba. With the latter, the physician also may prescribe topical steroid cream.
- Even when both conditions are treated, white patches can remain. It can take at least several weeks before the healthy skin adjusts its color to match surrounding skin.
