Common Rashes of the Skin : Part 3- Tinea Versicolor

Tinea versicolor (TV) is a common fungal infection affecting mostly adolescents and young adults.  The condition is seen most often in tropical regions where the weather is hot and humid.  Despite the name, TV is not in the same family as ringworm (tinea). Also unlike ringworm, it is not contagious from one person to the next.  Tinea versicolor is caused from a fungus that naturally already lives on many people’s skin, but only causes TV in some individuals.

The term “versicolor” refers to the various skin color changes that may be seen with this condition, including light patches, dark patches, pinkish patches, or a combination.   There may be small scales on the patches, and mild itching may be present.  TV is seen most commonly seen on the trunk, upper arms, and upper legs.

Factors that contribute to development of TV include exposure to hot and humid weather, excessive sweating, and usage of skin oils.  TV is not caused by poor hygiene.

Treatment consists of topical or oral antifungals.  TV responds well to therapy, however it does have a tendency to reoccur.  If TV recurs frequently, preventative measures with washes and/or creams can be used. After treatment, the skin may take months to return to its normal color.
