Purpose: The aim of the current study was to compare vascularity and angiogenic activity in peripheral and central giant cell granulomas (GCGs) of the jaws as reflected by vascular endothelial growth factor (VEGF). Patients and Method: 3 males and 7 females complaining of peripheral giant cell granuloma (PGCGs) and fifteen (5 males & ten females) with central giant cell granuloma (CGCGs) were selected to assess and compare the VEGF immunoexpression in multinucleated giantcells, and mononuclear surrounding stroma. Results: The expression levels of VEGF were greater in CGCGs compared to PGCGs and in aggressive CGCG more than non-aggressive. Conclusion: The vascularity and level of angiogenesis within aggressive CGCGs are higher than those in non-aggressive lesions. The stronger VEGF expression, the higher clinical behavior aggressiveness of the different giant cells granuloma lesions.
