  • Tinea versicolor is a common superficial fungal infection of the skin, causing hypo or hyperpigmented (“versicolor”), slightly scaly macules on the trunk, neck, and upper arms (short-sleeved shirt distribution). They are easier to see in darker skin and may be more obvious after tanning. In lighter skin, macules may look reddish or tan instead of pale.
