What is the main characteristic of tinea versicolor?

Tinea versicolor, also known as pityriasis versicolor, is primarily characterized by depigmentation or discoloration of the skin. This condition is caused by an overgrowth of a type of yeast that is normally found on the skin, leading to the disruption of the normal pigmentation process. As a result, affected areas may appear lighter or darker compared to the surrounding skin, which is particularly noticeable after sun exposure.

This condition does not typically present with blistering, itching, or significant scaliness, although some mild flaking may occur. The focus on depigmentation is crucial because it distinguishes tinea versicolor from other skin conditions that may exhibit similar symptoms, such as a rash or inflammation. Understanding this main characteristic helps identify the condition and differentiate it from other dermatological issues that may have overlapping symptoms but differing underlying causes and treatments.
