[edit | edit source]
Pityriasis or tinea versicolor is a common chronic superficial fungal skin infection of the upper trunk, neck, and upper arms caused by the organism Mallassezia furfur (Mellen et al and Levin).
Prevalence[edit | edit source]
It is frequently seen in tropical regions, with prevalence as high as 40%; it is also common in temperate areas, representing up to 3% of patients seen by dermatologists during the summer months. Children age 0-15 years had a 17.8% prevalence of pathogens of the genus Malassezia in the skin. The highest prevalence of colonisation was 23.3% in infants age 0-18 months and 26.7% in 11-15 year-olds. (Schwartz)
The species of Malassezia that are involved are Mglobosa (77%-90% of affected patients in Spain, 55% in Japan, 25% in Canada), M. sympodialis (32%-42% in Spain, 9% in Japan, 59% in Canada). and M. furfur (11% in Canada). (Levin)
US National Health Survey data from 1971-1974 showed a prevalence of 0.8% among people 1-74 years old in the United States. (Mellen).
