Ameloblastic carcinoma is an exceptionally rare odontogenic tumor. Ameloblastoma is considered malignant if there is evidence of metastasis or histological features of malignancy. Present classification of these tumors is debated. Several authors use the term malignant ameloblastoma for tumours that metastasize despite "benign" histological features whereas ameloblastic carcinoma is referred to as a tumor with malignant histological features regardless of its metastatic potential. We report a case of mandibular ameloblastic carcinoma with cervical lymph node metastasis in a 70-year-old man, documented by MRI and CT. We discuss current knowledge on these tumors.
