Mucormycosis causing extensive destruction of maxilla.

Mucormycosis is a rare, often fatal opportunistic infection caused by a saprophytic fungus belonging to a class of Phycomycetes. It is characterized by its unrelenting progression towards vital organs with marked propensity towards arterial wall by direct extension producing vascular thrombosis leading to ischaemic necrosis. In normal circumstances the saprophytes are not pathogenic but represent opportunist-requiring impairments in patient's resistance to disease. If not treated the disease may prove fatal. We report a case of Mucormycosis with extensive necrosis of the maxilla in a 57-year-old patient suffering from uncontrolled diabetes with ketoacidosis.
