Primary intraosseous carcinoma/odontogenic carcinomas are extremely rare malignant odontogenic tumours that are thought to arise from residues of odontogenic epithelium. An unusual case of primary intraosseous carcinoma arising de novo in a previously unreported site of posterior maxilla is described. The tumour was characterized by sheets of pleomorphic round-to-ovoid cells and marked osteoid/dentinoid formation with foci of globular mineralization.
