Case Report: Destructive deep infection of the foot caused by Neoscytalidium dimidiatum leading to great toe amputation.

We report an invasive deep-tissue infection caused by Neoscytalidium dimidiatum in a diabetic patient in China. Although typically a phytopathogen restricted to superficial human infections, it caused rapid necrosis necessitating hallux amputation. This case highlights the need for clinical awareness regarding the pathogenic potential of N. dimidiatum in immunocompromised hosts.
