Overview
Tinea versicolor is a long-term (chronic) fungal infection of the skin.
What are the symptoms of Tinea versicolor?
The main symptom is patches of discolored skin with sharp borders (edges) and fine scales. The patches are often dark reddish-tan in color. The most common sites are the back, underarms, upper arms, chest, and neck. Affected areas do not darken in the sun (skin may appear lighter than surrounding healthy skin)
In African Americans, there may be loss of skin color (hypopigmentation) or an increase in skin color (hyperpigmentation).
Other symptoms include:
- Increased sweating
- Itching
What causes Tinea versicolor?
Tinea versicolor is relatively common. It is caused by the fungus Pityrosporum ovale, a type of yeast that is normally found on human skin. It only causes problems under certain circumstances.
Who is at highest risk?
The condition is most common in adolescent and young adult males. It typically occurs in hot climates.
Diagnosis
A skin scraping that is examined under a microscope should show the yeast.
When to seek urgent medical care?
Call for an appointment with your health care provider if you develop symptoms of tinea versicolor.
Treatment options
Treatment consists of applying antifungal medicines to the skin. These medications include clotrimazole, ketoconazole, and miconazole.
Over-the-counter dandruff shampoos applied to the skin for 10 minutes each day in the shower may also help treat the skin.
