The evaluation of tinea versicolor begins with a history and physical exam.

Physical findings in someone with tinea versicolor include:

  • Rash:
    • Patches of skin that may be lighter or darker than the surrounding skin
  • Mild flaking of the skin

The diagnosis of tinea versicolor can usually be made without testing.

  • Skin scraping:
    • For examination under the microscope
