Mucormycosis is a type of an opportunistic fungal infection, which most commonly involves structures in the maxillofacial region, such as the paranasal air sinuses, maxilla, and orbit and in advanced stages it may affect the brain. The most common route of its entry is through inhalation. A common predisposing condition is diabetes mellitus, leading to an immunocompromised state. We present a case of a 63-year-old female patient with widespread maxillary osteomyelitis following teeth extraction, which was later diagnosed as mucormycosis.
