Pityriasis versicolor: all your questions answered

Sweta Rai and Ian Coulson
Pityriasis (tinea) versicolor (PV) is an extremely common skin eruption seen in daily clinical practice. It is a benign, superficial skin infection caused by the Pityrosporum yeast family. Its prevalence is as high as 40% in tropical climates. No precise data are available for its incidence in the UK, but it is thought to be less than 1% in colder climates, with an increase in cases during the hot and humid months of the year.
