%X UNASSIGNED: Central giant cell granuloma (CGCG) is a fairly common lesion involving the jaw bones. CGCG can show relatively innocuous biological behaviour or it may show clinicoradiological features suggestive of aggressive biological behaviour. To date, there are no histological parameters which can be used to predict the behaviour of these lesions. This study was conducted to assess the utility of parameters of angiogenesis, i.e., total vascular area (TVA), mean vascular area (MVA) and microvessel density (MVD), and density of myofibroblasts in aggressive and non-aggressive CGCGs.
UNASSIGNED: The study was undertaken as a retrospective study. A total of 20 previously diagnosed cases (10 non-aggressive and 10 aggressive) of CGCGs were included in the study. The sections were subjected to immunohistochemistry using the markers CD34 and α-SMA. For the assessment of vascular parameters, image J software was used. The density of myofibroblasts was determined in each case ranging from score-1 to 4, using the criteria given by Sridhara et al. The correlation between mean values of vascular parameters and density of myofibroblasts with aggressiveness of CGCG was assessed using Mann-Whitney U test.
UNASSIGNED: The result of Mann-Whitney U test suggested that the differences between the values of TVA (P < 0.001), MVA (P < 0.003) and density of myofibroblasts, i.e., SMA mean (P < 0.001) and SMA score (P < 0.001), in two groups are statistically significant. The formula for the assessment of aggressiveness was obtained using discriminant analysis.
UNASSIGNED: Angiogenesis and density of myofibroblasts significantly differ in aggressive and non-aggressive cases of CGCGs. The aggressiveness of CGCG case can be predicted using the obtained formula by entering the values of vascular parameters and myofibroblasts.
