Carcinoma arising as a primary tumor within the jaw is rare. According to the World Health Organization (WHO): International Histologic Classification of Tumours, primary intraosseous carcinoma (PIOC) is defined as a squamous cell carcinoma arising within the jaw, having no initial connection with the oral mucosa, and presumably developing from residues of the odontogenic epithelium.

This article reviewed twenty-seven cases of PIOC among Japanese and described the clinicopathological features.
