How is pityriasis versicolor diagnosed?

Dr. Mehmet Oz, MD
Cardiology (Cardiovascular Disease)
Pityriasis versicolor usually can be diagnosed by a doctor or dermatologist with a simple medical examination of the affected skin. Sometimes, if the doctor cannot make a positive diagnosis by looking at your skin, he or she may examine your skin through a special piece of equipment called a Wood's lamp. If you have pityriasis versicolor, it will appear yellowish green under this lamp. Another diagnostic option is to gently scrape a small bit of affected skin. This skin sample is examined under a microscope.

If you have any questions about the diagnosis of pityriasis versicolor, talk to your doctor or dermatologist.
