Tinea versicolor (TV) is a skin infection that causes areas of the skin to change color. The skin might have lighter patches, darker patches, or both light and dark patches.
TV is caused by a fungus. This fungus lives on people’s skin and does not cause problems normally. But in some people, the fungus can cause TV. This happens more often in people who live where the weather is hot and humid.
Even though tinea versicolor is caused by fungus, it does not spread from one person to another. It is not “contagious.”
Where Tinea versicolor found ?
TV occurs worldwide, but the highest incidence is found in tropical climates.
Prevalence of up to 50 percent has been reported in some tropical countries . In Scandinavia, the prevalence has been estimated to be approximately 1 percent .
TV most commonly affects adolescents and young adults, but can also occur in children and has been reported in infants .
The disorder is not contagious, although successful inoculation has occurred under experimental conditions utilizing topical oils and occlusion .
Dr. Oller talks about TV. Diagnosis, treatment, follow up
Patients with TV often present with hypopigmented, hyperpigmented, or erythematous macules on the trunk and proximal upper extremities . Unlike other disorders utilizing the term tinea (eg, tinea pedis, tinea capitis), TV is not a dermatophyte infection. The causative organisms are saprophytic, lipid-dependent yeasts in the genus Malassezia (formerly known as Pityrosporum) .
Tinea versicolor responds well to medical therapy (table 1), but recurrence is common and long-term prophylactic therapy may be necessary. The clinical features, diagnosis, and management of TV will be reviewed here.
