“Pityriasis alba is Latin for white, scaly patches and it is the most common cause for them in childhood. Children with this extremely common condition develop uneven, round or oval patches after sun exposure. The patches are dry with very fine scales. Varying from 1 to 2 inches in diameter, they are most common on the face (cheeks), neck, upper trunk, and upper arms of children 3 to 16 years old.
