case_images: Clinical examination of the affected area revealed gray-colored exposed bone in the maxillary anterior area, and a panoramic radiograph taken before extraction showed diffused rarefaction of the alveolar process and the hard palate [Figure 1].

case_images: Based on these features, a provisional diagnosis of maxillary osteomyelitis was made followed by excision of anterior maxilla [Figure 3].

case_images: H and E stained section revealed pseudostratified ciliated columnar epithelium with edema in the submucosal areas with dense inflammatory infiltrate chiefly composed of eosinophil's interspersed with multiple colonies of thick nonseptate fungal hyphae, branching at right angles to obtuse angles, which were surrounded by extensive necrotic debris based on histopathological features diagnosed as mucormycosis [Figures 4-6].

case_images: This was followed by complete excision of the maxilla, as necrosis extends up to zygomatic bone, and surgical reconstruction of the maxilla was done [Figure 7].
