From the Research
Tinea versicolor is characterized by scaly hypopigmented or hyperpigmented macules/patches, primarily located on the upper trunk, neck, and upper arms, as noted in the most recent review 1. The condition is caused by the overgrowth of Malassezia yeast, a normal skin flora that becomes problematic in certain conditions like heat, humidity, and excessive sweating. Some key physical findings include:
- Hypopigmented or hyperpigmented macules and patches on the skin
- Fine scale that may only be visible when the skin is stretched
- Patches can be white, pink, tan, or brown, and typically don't tan with sun exposure
- Mild itching in some patients, though many are asymptomatic except for the cosmetic appearance The diagnosis can be confirmed by examining skin scrapings under KOH preparation, which reveals short hyphae and round yeast cells, or by using Wood's lamp examination, which may show a yellow-golden fluorescence 1. It's worth noting that while various treatments are available, including topical and oral antifungal therapies, the most effective approach will depend on the individual patient's needs and the severity of the condition, with topical antifungal therapy generally being the first-line treatment 1.
