Correlation of histopathologic features with demographic, gross and radiographic findings in giant cell granulomas of the jaws.

Background and aims. The correlation between morphology of giant cells in peripheral granulomas of the jaws and the aggressive behavior of the lesion is unknown. This study investigated the correlation between the histopathologic features with demographic, gross and radiographic findings in giant cell granulomas. Materials and methods. In this analytical study, data from 23 cases of central giant cell granuloma (CGCG) and 42 cases of peripheral giant cell granuloma (PGCG) were analyzed, focusing on age, gender, location, and gross and radiographic features. For each patient, microscopic slides were assessed in terms of histologic features of giant cells and stroma. Results. No significant differences were found in the mean number of nuclei or the size of nuclei and giant cell distribution patterns between the jaws and genders in both lesions (P >0.05). Correlation between the mean number of nuclei and age was positively significant and correlation between the size of nuclei and age was negatively significant (P < 0.05). In addition, correlation between the mean number and size of nuclei and the size of the lesion was significant (P < 0.05). Correlation between stroma and aggressiveness of CGCGs was not statistically significant. Correlation between histopathologic features and radiographic findings was not statistically significant (P > 0.05). Conclusion. There were correlations between the mean number of nuclei per giant cell and the size of the lesion and age, and between the size of nuclei and size of the lesion. No relation was observed between histopathologic and radiographic features.
