Cement forming tumours of the lower jaw (case report)

This publication concerns two cement forming tumours - the centrally cementifying fibroma and the true cementoma. The centrally cementifying fibroma is a rare tumour and has been considered an entity for some time. Our case presents a lesion of a size and a homogeneous histological structure rarely encountered. The operative procedure is also discussed. The progression from the radiolucent to the radio-opaque stage could be observed radiologically in the case of a cementoma.
