Pityriasis alba (PA) is a benign inflammatory dermatosis affecting about 5% of infantile population, frequently seen in tropical areas of the world. This entity has received many synonymous such as chronic impetigo and erythema streptogenes, but its actual name was given from Hazen. PA is also considered a minor criterion for the diagnosis of atopic dermatitis. It is characterized by hypopigmented, irregular plaques with well-defined borders, covered by fine scales; it affects mainly face, limbs and occasionally thorax.
