Other superficial mycoses: Causes, Symptoms, and Treatment
Superficial mycoses are fungal infections that affect the outermost layers of the skin, hair, and nails. Although they are not life-threatening, these infections can cause discomfort and embarrassment. Other superficial mycoses are a group of fungal infections that affect the skin and nails, causing different symptoms and requiring specific treatment.
- Pityriasis versicolor: This type of superficial mycosis is caused by a yeast called Malassezia furfur. It usually affects young adults and is more common in warm and humid climates. The symptoms include patches of discolored skin that can be lighter or darker than the surrounding skin. The patches can be itchy, and sometimes they flake off like dandruff. Treatment options include antifungal creams, lotions, and shampoos.
- Tinea nigra: This superficial mycosis is caused by a fungus called Exophiala werneckii. It usually affects people who live in tropical areas and spend a lot of time outdoors. The symptoms include dark brown or black patches on the skin, usually on the palms of the hands or the soles of the feet. The patches are not itchy, and they do not flake off. Treatment options include topical antifungal creams and lotions.
- Tinea versicolor: This superficial mycosis is caused by the same yeast that causes pityriasis versicolor (Malassezia furfur). However, it presents with different symptoms. The most common symptom is the appearance of scaly, white or pink patches on the skin. The patches can be itchy, and they tend to be more noticeable in areas of the body that are exposed to the sun, such as the arms, neck, and chest. Treatment options include antifungal creams, lotions, and shampoos.
- White piedra: This superficial mycosis is caused by a fungus called Trichosporon spp. It affects the hair shafts and causes the formation of white or light brown nodules that adhere to the hair. The nodules can make the hair look dirty or lumpy. The infection is more common in warm and humid climates. Treatment options include antifungal shampoos and topical antifungal creams.
If you suspect that you have a superficial mycosis, it is essential to seek medical advice. Your doctor can diagnose the infection by examining the affected skin, hair, or nails and taking a sample for laboratory analysis. Treatment options depend on the type and severity of the infection, but they usually involve antifungal medications. In addition to medication, there are some measures you can take to prevent the spread of the infection, such as keeping the affected area clean
