What is pityriasis alba?

Answer 12

Pityriasis alba,common in children 3 to 16 years of age, presents as hypopigmented macules. They most often occur on the face, neck, trunk, and extremities. They have irregular borders, can vary in size, and may have a slight scale. Lesions may become more noticeable after sun exposure because of tanning of the surrounding skin. The etiology of this disorder is unknown, but ultrastructural examination of epidermal cells reveal decreased number of active melanocytes as well as decreased number and size of melanosomes.
