Tinea versicolor: It's possibly tinea versicolor. It's caused by a fungus, which blocks the sunlight from activating the melanocytes (pigment cells) in your skin. With sun exposure, the skin around it tans but the fungal area stays white. You'll need a doctor's examination for a diagnosis.http://www.aad.org/dermatology-a-to-z/diseases-and-treatments/q---t/tinea-versicolor.
