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.

Follow-up testing showed no infection, and the baby improved without antifungal treatment, suggesting it was contamination rather than true disease. However, this finding is important because this yeast has been known to cause serious infections in premature babies in hospital settings.

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.
