ABSTRACT

Pityriasis alba is a very common benign hypopigmented condition in children living in Latin-American countries. It has a chronic self-limited course and no relation to internal diseases. Characterized by asymptomatic white blotchy and scaly plaques in skin exposed to sunlight. Likely associated with the atopic phenotype; prophylactic and therapeutic measures include hydrating and emollients, although results might not be satisfactory since there isn´t any definitive treatment for this disorder. Due to the development of the disease, most parents are concerned about the uneven pigmentation that results in non-aesthetic appearance with medical and social implications.
