A 23-year-old woman developed a severe fungal infection in the genital area caused by a fungus normally found on dogs. Her initial antibiotic treatment failed because the infection was actually fungal, not bacterial. After diagnosis through fungal culture, she was successfully treated with antifungal medications, though the infection left some scarring and discoloration. This case highlights how genital fungal infections can be difficult to diagnose because they look similar to bacterial infections.
