[Classification of epitheliomesenchymal odontogenic tumors]

In a group of 34 epitheliomesenchymal odontogenic tumours no difficulties were encountered in recognizing the seven-member group of ameloblastic fibroma (with ameloblastic odontoma and dentinoma included as variants) as distinct from group of odontomas (ameloblastic o. - 2x, complex o. - 20x, combined o. - 5x) The definition is rather a general one with the distinction of variants only sometimes possible. No ameloblastic fibrosarcoma or ameloblastic odontosarcoma were seen in the group; therefore, the question should be asked whether it is really expedient to keep independent places in the classification for so rare tumours.
