    Tinea versicolor

    Pityriasis versicolor

    Tinea versicolor is a long-term (chronic) fungal infection of the skin.

    Causes

    Tinea versicolor is fairly common. It is caused by a type of yeastfungus calledPityrosporum ovale. THis fungus is normally found on human skin. It only causes a problem in certain settings.

    The condition is most common in adolescent boys and young adult men. It typically occurs in hot climates.

    Symptoms

    The main symptom is patches of discolored skin that:

    • Havesharp borders (edges) and fine scales
    • Are often dark reddish-tan in color
    • Are found on the back, underarms, upper arms, chest, and neck
    • Do notdarken in the sun so may appear lighter than surrounding healthy skin

    African Americans may have a loss of skin color (hypopigmentation) or an increase in skin color (hyperpigmentation).

    Other symptoms include:

    • Increased sweating
    • Itching

    Exams and Tests

    The health care provider will examine a skin scraping that is examined under a microscope to look for the yeast.

    Treatment

    The condition is treated by applying antifungal medicines to the skin. These medicines include clotrimazole, ketoconazole, and miconazole. Anti-fungal medicines you take by mouth can also be used.

    Applying over-the-counter dandruff shampoosto the skin for 10 minutes each day in the shower is another treatment option.

    Outlook (Prognosis)

    Tinea versicolor is easily treated. Changes in skin colormay last for months. The condition may come back during warm weather.

    When to Contact a Medical Professional

    Call your health care provider if you develop symptoms of tinea versicolor.

    Prevention

    Avoid excessive heat or sweating if you have had this condition in the past. You can also use anti-dandruff shampoo on your skinevery month to help prevent the problem.
