Fatal fungal infection: the living dead

Necrotizing fasciitis is an uncommon infection mainly caused by Streptococcus pyogenes, which is also known as flesh-eating bacteria. It is often caused by bacteria, but can also be caused and complicated by fungus. We report a case of bacterial necrotizing fasciitis that was complicated by a fatal fungal infection, a rare clinical presentation affecting the upper limbs, head and neck, in a young diabetic female patient. It was an unsuspected case of fungal infection with mucormycosis, which proved to be fatal due to a delay in diagnosis and treatment.
