Background: Mucormycosis is a fungal infection commonly affecting structures in the head and neck, such as air sinuses, orbits and the brain. Common predisposing factors include diabetes and immunosuppression, although it can rarely occur in people who are otherwise healthy. Mucorales possess virulence factors that enable the organism to cause disease. One such trait is the ability to acquire iron from host. The rich vascularity of maxillofacial areas usually prevents fungal infection although more virulent fungi such as those responsible for mucormycosis can often overcome this difficulty. Rapid diagnosis and initiation of therapy is critical due to acute fulminant nature of infection. In most cases, the infection is relentlessly progressive and results in death unless treatment with a combination of surgical debridement and antifungal therapy is initiated promptly. One such case of mucormycosis associated with diabetes mellitus reported to our department with an old maxillary fracture on right side
