Purpose:
The aim of this retrospective study was to investigate the characteristics of cemento-osseous dysplasia (COD) lesions for devising a clinical algorithm to help management decisions, specifically discussing the need for a possible surgical intervention versus solely follow-up.
Materials And Methods:
One hundred thirty-five subjects were thus identified having previously diagnosed and treated for COD from the archives of the pathology in between 2005-2015. These were then re-evaluated. Demographic features, radiographic and histopathologic findings were assessed.
Results:
The most frequent variant was the focal type (n=83), and the mandible (n=131) was predominantly affected jaw bone. Female predilection was evident for all subtypes. Almost half of the lesions (n=72) presented with mixed radiolucent and radiopaque appearances in radiography at the time of the biopsy. Cementicles/psammoma body-like calcifications and trabecular pattern were the most common hard tissue appearances.
Conclusion:
COD lesions are non-neoplastic fibro-osseous lesions which can exhibit similar histopathologic and radiologic features with other bone lesions. Ideally, these lesions should be clinically identified and followed-up. Considering the possible complications, a thorough knowledge of these lesions and their differentials is essential in order to avoid unnecessary surgical interventions.
