Tinea versicolor caused by Malassezia infection

Tinea Versicolor, Skin Infection Caused by Malassezia

Tinea versicolor is a common skin condition caused by a type of yeast called Malassezia. The yeast lives on the skin of most people without causing problems. However, some people may develop an excessive growth of Malassezia, which leads to tinea versicolor.

The infection causes patches of discolored, often scaly skin to form on the back and chest. It can also occur on the face, neck, arms, and legs. The patches may be lighter or darker than the surrounding skin, and can become itchy or sore. Tinea versicolor can affect people of any age, but it is most common in adolescents and young adults.

Tinea versicolor is not contagious, and it is not usually a serious problem. Treatments such as antifungal creams and shampoos are available to clear up the skin patches.

Signs and Symptoms of Tinea Versicolor

  • Scaly, discolored patches on the skin
  • Patches can be lighter or darker than the surrounding skin
  • Patches may be itchy or tender
  • Patches often occur on the back, chest, and face
  • Can also occur on the arms and legs

Causes of Tinea Versicolor

Tinea versicolor is caused by an overgrowth of a type of yeast called Malassezia. This yeast is found on the skin of most people and is usually harmless. However, in some cases, the yeast may overgrow and cause tinea versicolor.

The yeast feeds on fatty acids in the skin’s oils, which can cause an imbalance in the skin’s oils. This can cause the skin to become dry, scaly, and discolored.

Treatments for Tinea Versicolor

Tinea versicolor is usually not a serious condition and can be treated with antifungal creams or shampoos. These medications are often applied twice a day for two to four weeks, until the skin patches disappear.

It is important to follow the instructions on the medication label. In some cases, the patches may recur and require additional treatment.
