Tinea versicolor is generally referred to as pityriasis simplex, which clinically manifests as flaky hypopigmented patches on the surface of the skin that are covered with fine scales. Furuncle simplex is characterized by skin changes including hypopigmented patches with blurred borders, fine scales, and mild itching. The lesions occur mainly on the facial skin, but can also appear on the neck, upper limbs, and the back of the shoulders, and children are the most common people with pityriasis versicolor. Furfura simplex needs to be differentiated from vitiligo and tinea corporis. Vitiligo can be excluded if the affected skin does not fluoresce when examined with a Wood’s lamp. Fungal infection can be ruled out if no hyphae or spores are found in the scales or skin of the lesions. If you have flaky hypopigmented patches covered with thin scales, it is advisable to consult a doctor in time for examination and treatment under the doctor’s guidance.
