Malignant intraosseous odontogenic tumors (MIOT) of the jaws are very rare. The diagnosis is difficult. Clinical, paraclinical and histological diagnostic criteria, strict are well established. But the International Union Against Cancer (UICC) does not provide TNM classification that will allow harmonization of the treatment. Indeed, despite their location, they cannot be classified as primary tumors of the oral cavity because of their localization in the bone marrow, making them systematically classified as T4.We propose a classification taking into account the clinical and radiological data.
