Abstract
Mucormycosis is a rare potentially fatal opportunistic fungal infection that affects human beings. Normally, a healthy is immune to such infections but there are some risk factors which predispose a person to mucormycosis, of which malnutrition and diabetes mellitus are the most common risk factors. India is the most commonly affected country by mucormycosis because of high proportion people with low socioeconomic status and diabetes mellitus. In diabetes mellitus, mucormycosis is more aggressive and fatal due to an impaired host defense mechanism. In spite of being a rare and fatal fungal infection, early diagnosis and prompt multidisciplinary treatment comprising control of underlying predisposing factor, surgical management, and medical management can be helpful in such cases.
