Abstract

Vascular Endothelial Growth Factor, also known as Vascular Permeability Factor, is a multifunctional cytokine hyperexpressed during angiogenesis and in numerous physiological and pathological processes characterised by an increase of vascular permeability. The aim of this study was to evaluate the angiogenetic processes which are accompanied by an expansion of cystic radicular lesions and of keratocysts of the jaw bone. 12 subjects were chosen with an average age of 43 years, of whom 8 were males and 4 females. After an accurate history and physical examination, the patients underwent surgery for removal of the cysts. The samples taken were histologically and immunohistochemical examined. The histological exam confirmed the diagnosis of radicular cysts and keratocysts. The immunohistochemical examinations were positive for VEGF in all the lesions analysed, even though they had different immunostaining. Using a semi-quantitative method, in the radicular cyst samples it was possible to highlight a wider expression of the vascular component, both in the inflamed area and the adjacent stroma. The lesions with keratin content showed newly formed and modest vascularisation both in the area showing slight inflammation, where the cellular component was prevalent, and in the adjacent areas showing no inflammation. Therefore, angiogenesis could take on a primary role in the development of cystic lesions of the jaw. However, the differences of expression of the VEGF protein suggest the need for wider monitoring to better evaluate a possible use of such a protein as a diagnostic marker.
