Tinea versicolor is a common fungal infection of the skin. The fungus interferes with the normal pigmentation of the skin, resulting in small, discolored spots. These patches can be lighter or darker in color than the surrounding skin and most commonly affect the trunk and shoulders.
Tinea versicolor (TIN-ee-uh vur-si-KUL-ur) occurs most often in adolescents and young adults. Sun exposure can make tinea versicolor more noticeable. Tinea versicolor, also called tinea versicolor, is not painful or contagious. But it can lead to emotional distress or embarrassment.
Antifungal creams, lotions, or shampoos can help treat tinea
versicolor. But even after successful treatment, the skin color may
remain uneven for several weeks or months. Tinea versicolor returns
often, especially in hot, humid weather.
Symptoms
Signs and symptoms of tinea versicolor include:
Patches of discoloration of the skin, usually on the back, chest,
neck, and upper arms, which may appear lighter or darker than usual
Mild itching
Scaling
When to consult a doctor
See your doctor if:
Your skin does not improve with self-care measures
The fungal infection returns
The patches cover large areas of your body
Causes
The
fungus that causes tinea versicolor can be found on healthy skin. It
only begins to cause problems when the fungus overgrows. A number of
factors can trigger this growth, including:
Hot and humid weather
Oily skin
Hormonal changes
Weakened immune system
Prevention
To
help prevent tinea versicolor from coming back, your doctor may
prescribe a skin or oral treatment that you use once or twice a month.
You may need to use them only during the hot and humid months.
Preventive treatments include:
2.5 percent selenium sulfide (Selsun) lotion or shampoo
Ketoconazole (Ketoconazole, Nizoral, others) cream, gel or shampoo
Itraconazole (Onmel, Sporanox) tablets, capsules or oral solution
Fluconazole tablets or oral solution (Diflucan)
