The patches are primarily located on the upper part of the torso, shoulder girdle, neck, and sometimes upper arms. The size of the patches is usually 1-2 cm, but when numerous, they can merge into larger patches. There is very fine scaling, which is more visible when the skin is slightly stretched between two fingers. Pityriasis versicolor typically causes white patches, though sometimes they are red or light brown. Long-standing pityriasis versicolor can lead to prolonged or even permanent pigment loss in the affected areas. Therefore, it is important to treat it timely and correctly.
Symptoms
Pityriasis Versicolor is characterized by discolored patches on the skin, which can range from white, pink, salmon-colored to brown. These patches are usually found on the back, chest, neck, and upper arms. Some people experience mild itching, especially when warm or sweating, and the skin may be slightly flaky.
Causes
The condition is caused by an overgrowth of the yeast Malassezia, which naturally resides on the skin. Factors such as warm, humid climates, oily skin, weakened immune systems, and genetic predisposition can contribute to this overgrowth.
Diagnosis
The diagnosis is usually made based on the appearance of the skin, sometimes supplemented by a skin scrape under a microscope or an examination with a Wood’s lamp, which can reveal a specific glow on the affected skin.
Treatment
Treatment options include antifungal creams, lotions, or shampoos, and sometimes oral antifungals. Repeated treatment may be necessary as the condition can recur.
Self-care tips
To prevent recurrence, it is recommended to keep the skin dry, wear lightweight and breathable clothing, regularly use antifungal products, and limit the use of oily skin products.
