A 52-year-old woman with lupus developed a widespread fungal skin infection that was initially mistaken for worsening lupus symptoms. The infection affected her scalp, face, and nails with two different types of fungi. After six months of treatment with antifungal medications, her symptoms resolved completely with no return of the infection during follow-up.
Tinea capitis, commonly known as scalp ringworm, is a fungal infection that primarily affects children but can also occur in adults, especially postmenopausal women. This study of 454 patients in Hangzhou, China found that the most common cause is Microsporum canis (a fungus from cats and dogs), representing a shift from previous decades when different fungi were dominant. Researchers tested how well these fungi grow at human body temperature (37°C) versus room temperature, finding that most fungi adapt well to the warmer temperature, particularly Nannizzia gypsea, which grew equally well at both temperatures. Treatment typically involves oral antifungal medications like terbinafine or itraconazole, sometimes combined with topical treatments or steroids for inflammatory cases.
A 60-year-old woman developed unusual hair loss and rash on her scalp that looked like dandruff. Tests revealed three types of fungi, including Microsporum canis (usually found in animals) and two types of Malassezia yeast. Treatment with antifungal medications for three months cleared the infection. Laboratory experiments showed that the yeast species may actually help the fungus grow better, which could explain why adults sometimes get scalp fungal infections differently than children.
This paper describes a rare condition where patients develop painful red bumps on the shins (erythema nodosum) as a reaction to a severe scalp fungal infection (kerion) caused by Trichophyton mentagrophytes. The authors reviewed 23 similar cases and found that this reaction usually happens during antifungal treatment and resolves within about a week. Treatment with antifungal medications like griseofulvin, sometimes combined with anti-inflammatory steroids, is effective, though scarring of the scalp may remain.
This study examined fungal skin infections in children and teens in Northern Poland over six years, finding that about 1 in 5 children tested had a fungal infection. Different types of fungal infections were more common at different ages—younger children more often had scalp infections, while teenagers more often had foot and nail infections. The study found that children living in rural areas had higher infection rates than those in cities, suggesting that environmental factors play an important role in fungal infection patterns.
A 60-year-old woman developed unusual hair loss and scalp inflammation that looked like dandruff but was actually a fungal infection caused by multiple fungi working together. Doctors found three different fungi in her scalp samples: one dermatophyte and two Malassezia species. Lab experiments showed that the Malassezia fungi actually helped the main disease-causing fungus grow better, which explains why the condition looked different from typical cases. After three months of antifungal medication, her symptoms cleared and her hair grew back.
Researchers in Iran studied fungal infections of the scalp and nails using modern DNA testing methods. They found that the main fungus causing scalp infections (T. tonsurans) remains the most common, but a new species (T. indotineae) is increasingly causing nail infections and is resistant to common antifungal medicines. The study shows that traditional identification methods often misidentify these fungi, highlighting the importance of molecular testing for accurate diagnosis and treatment.
This study examined fungal skin infections in children and teenagers in northern Poland from 2019 to 2024. Researchers tested over 1,200 young patients and found that about 1 in 5 had a fungal infection. The most common culprits were specific fungi that cause scalp infections in young children and foot/nail infections in teenagers. Interestingly, children living in rural areas were more likely to have these infections, even though more urban children were tested.
Researchers studied fungal skin infections in a community in northeastern Argentina, finding that 37% of patients had these infections. The most common cause was a fungus called Trichophyton tonsurans. Poor living conditions like overcrowding and lack of clean water increased infection risk. The study shows that fungal skin infections are a significant health problem in areas with limited access to basic sanitation and water services.
This study examined fungal skin infections caused by dermatophytes in a Moroccan hospital over four years, analyzing 950 samples. The researchers found that nail infections (onychomycosis) were most common, particularly in people over 50 years old, while scalp infections mainly affected children. The fungus Trichophyton rubrum was responsible for most infections, though Microsporum canis increasingly caused scalp infections, likely due to increased pet ownership in Morocco. The study emphasizes the importance of proper laboratory testing to identify the specific fungus and choose appropriate treatment.
