Pityriasis Alba: A Condition with Possibly Multiple Etiologies
Abstract
Pityriasis alba is a common hypomelanosis which is generally seen in young children. There is no specific known cause for this condition; however, studies to elucidate pathogenic factors seem to suggest that there are at least five separate causes for the condition. This list includes dermatitis, photosensitivity, fungal and bacterial pathogenesis, and post-inflammatory alterations. An evaluation into causative factors translates into alternative therapeutic options, which may be advantageous with affected individuals.
