Abstract
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.
