Pityriasis alba
Pityriasis alba is a chronic dermatitis that may be recurrent. It presents as asymptomatic, multiple, oval, finely scaly, hypopigmented macules which range in size from 5 mm to 5 cm, typically on the face or extensor surfaces of the arms of infants or children. It begins with an erythematous inflammatory phase. It is very common and up to 40% of children can be affected and is more prominent in dark skinned children.
