Pityriasis versicolor, sometimes called tinea versicolor, is a common fungal infection that causes small patches of skin to become scaly and discoloured. Symptoms of pityriasis versicolor Patches of skin may be darker or lighter than your normal skin colour, or may be red, brown or pink.
Pityriasis versicolor is a common yeast infection of the skin, in which flaky discoloured patches appear on the chest and back.

Pityriasis versicolor (also known as tinea versicolor) is a common fungal infection of the skin that is localized to the outermost layer of the epidermis (the stratum corneum). It is caused by yeasts of the genus Malassezia, which are normal skin flora in more than 90% of adults.
In some patients pityriasis versicolor can be a recurrent problem and arises again when conditions are right for the Malassezia to proliferate. When this happens the rash will start again, or become more widespread and scaly if the skin had not had the time to revert back to its original state in the first instance
