Correlation of Vascular and Inflammatory Index in Oral Pyogenic Granuloma and Periapical Granuloma – An Insight into Pathogenesis
Journal Title: Journal of Clinical and Diagnostic Research - Year 2017, Vol 11, Issue 5
Abstract
Introduction: Angiogenesis is vital in the aetiology and pathogenesis of a number of pathological processes that include solid reactive lesions like pyogenic granuloma and chronic inflammatory disorders like periapical granuloma. Vascular Endothelial Growth Factor (VEGF) is a potent proangiogenic cytokine secreted by many cell types which present several pivotal functions in physiologic and pathologic angiogenesis. Aim: The aim of the present study was to evaluate and compare the expression of VEGF in oral Pyogenic Granuloma (PG) and Periapical Granuloma (PAG) and also to correlate with the inflammatory cell infiltrate. Materials and Methods: Paraffin embedded tissue blocks of histologically diagnosed cases of PG and PAG, 20 of each were retrieved from the archives. The cases were selected randomly to evaluate the expression of VEGF marker and to assess the Mean Vascular Count (MVC) index and inflammation by Morphological Index (MI). The results were analysed using Unpaired t-test, Mann-Whitney U test and spearman correlation coefficient-test. Results: The PG showed higher expression of VEGF when compared to PAG with no significant difference in inflammation. PG showed positive correlation and PAG showed negative correlation between inflammation and VEGF expression. Conclusion: Histologically similar PG and PAG are different not only by their clinical presentation but also by their mechanisms of formation and molecular sketch. Thereby raised expression of VEGF marker was established in PG emphasizing the fact that all histologically similar lesions need not have similar clinical course and molecular depiction.
