Invasive rhinomaxillary mucormycosis: a case report with a review of the literature

Mucormycosis is a rare, often fatal disease that is caused by zygomycetes, which are common fungi frequently found in the soil and decaying vegetation. Diabetes mellitus, malnutrition, and an immunocompromised state favor the growth of various microorganisms, including zygomycetes and the normal flora of the oral cavity, which are otherwise nonpathogenic, leading to opportunistic infections. Here we report a case of mucormycosis presenting with extensive necrosis of the maxilla along with rhinocerebral involvement in a 60-year-old patient suffering from uncontrolled diabetes with ketoacidosis.
