Tinea versicolorhttps://en.wikipedia.org/wiki/Tinea_versicolor
Tinea versicolor is a condition characterized by a rash on the trunk and proximal extremities. Most cases are caused by the fungus Malassezia globosa. These yeasts cause problems primarily under warm, humid conditions. Tinea versicolor is more common in hot, humid climates and in individuals who sweat heavily, and it often recurs each summer. Topical antifungal medications are recommended to treat tinea versicolor.
