Ameloblastic carcinoma is an exceptionally rare odontogenic tumor. Ame
loblastoma is considered malignant ii there is evidence of metastasis
or histological features of malignancy. Present classification of thes
e tumors is debated. Several authors use the term malignant ameloblast
oma for tumors that metastasize despite ''benign'' histological featur
es whereas ameloblastic carcinoma is referred to as a tumor with malig
nant 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 di
scuss current knowledge on these tumors.
