Classification of cemento-osseous lesions of the jaws has long been a
dilemma for pathologists. A group of 221 cemento-osseous lesions exhib
ited sufficiently distinctive clinicopathologic features to be separat
ed into a specific category: focal cemento-osseous dysplasia. This ent
ity presents as an asymptomatic, focal, mixed radiolucent/radiopaque l
esion with ill-defined borders in the tooth-bearing areas. It was foun
d to occur with greater frequency in women (88%) and in the posterior
mandible (77%). The average age at presentation was 37 years and a rel
ative predilection for black patients was observed. At surgery these l
esions were noted to be hemorrhagic, gritty, and adherent to the surro
unding bone. The gross appearance of multiple hemorrhagic fragments is
of diagnostic significance. Histologic features include a cellular co
nnective tissue stroma punctuated by irregular osseous and/or cementum
-like calcifications. Focal cemento-osseous dysplasia is thought to be
of periodontal ligament origin and to be non-neoplastic in nature. Fu
rther surgical intervention is not necessary, but periodic follow-up i
s recommended, because occasional cases were observed to progress into
florid osseous dysplasia. Care must be taken to differentiate focal c
emento-osseous dysplasia from central cementifying and/or ossifying fi
bromas, which are true neoplasms and required surgical treatment.
