Tinea versicolor

Tinea versicolor, also known as pityriasis versicolor or "sweat spots," is a non-contagious skin condition caused by Malassezia, a common fungus. This condition is more prevalent in young and middle-aged adults, with a higher incidence in males. The main symptoms include scattered brown, red, or white patches on the trunk or upper limbs, which may or may not be accompanied by itching.
