Pityriasis Versicolor in Children and Adolescents: an Update.

Purpose of Review: Pityriasis versicolor (PV) is a superficial mycosis that it can occur at any age, even in newborns. In this review, we will describe epidemiological data, mycological characteristics of yeast, pathogenesis and clinical characteristics of the disease, different diagnostic resources, and the current recommendations for treatment. Recent Findings: The typical morphology and topography of PV allow us to make a quick diagnosis, but atypical presentations have been described. Diagnostic tools, such as dermoscopy, can also reveal patterns that allow the evaluation of characteristics of scales and pigment in lesions. The discovery of new species and new mechanisms of interaction with the host has broadened the panorama of aetiological possibilities. Summary: Although PV is a common disorder, extensive research is necessary to better understand the pathophysiology of the disease, immunological characteristics of the pathogen-host relationship and resources needed to precisely diagnose the disease, treat the disease, and avoid its chronic and recurrent course.
