What is tinea versicolor? What are symptoms and signs of tinea versicolor?
Tinea versicolor is a common fungal infection of the skin that often affects adolescents and young adults. The term versicolor refers to the fact that it causes the affected skin to change color and become either lighter or darker than surrounding skin. The most common areas it affects are the shoulders, back, and chest. At times, it can affect folds of skin, such as the crook of the arm, the skin under the breasts, or the groin. The face is usually spared, although sometimes children can have the face affected. There may be just a few spots or so many that it gives the appearance that the affected skin is normal while the unaffected skin around it seems to have a problem.
What causes tinea versicolor?
Tinea versicolor is caused by yeast called Malassezia furfur that normally live on the skin of most adults without causing problems. It exists in two forms, one of which can cause patches of discolored slightly scaly skin. Factors that induce the disease are poorly understood, but high humidity and immune or hormonal changes may play roles. Most people with this very common condition are perfectly healthy.
Because the tinea versicolor fungus is part of the normal adult skin flora, this condition is not contagious in the usual sense. It often recurs after treatment, but usually not right away, so that treatment needs to be repeated only every year or two.
Tinea versicolor patches that are brown or reddish-brown go right away after treatment. This fungus produces a chemical, which seems to inhibit the normal production of pigment in the skin resulting in areas of lighter skin. It may take several months for overall color to even out. It always eventually does. Tinea versicolor does not leave permanent skin discoloration.
