Background: A typical non-neoplastic connective tissue proliferations called a pyogenic granuloma. A vascular adhesion molecule used to assess angiogenesis is the CD34 marker. The primary memberof a family of growth factors, VEGF helps in generating and maintaining the lymphatic and blood circulation systems.
Objective: The aim of the study was to know the correlation between VEGF and CD34 protein marker and pyogenic granuloma.
Methods: Thirty-one formalin fixed paraffin embedded (FFPE) blocks were taken from female pyogenic granuloma patients ranging in age from 29 to 70. The IHC was used to identify VEGF and CD34 expression in the cytoplasm of the cells.
Results: Seventeenout of 31 patients had VEGF positive expression. Twenty-sixout of 31 had CD34 positive expression and 5 with no expression (negative expression). Brown-stained cytoplasm showed high VEGF and CD34 expression, whereas blue stained cytoplasm showed no VEGF and CD34 expression in these cells.
Conclusions: The results suggest the role of suchbiomarkers in the oral pyogenic granuloma pathogenesis, and it appears that CD34 and VEGF are valuable biomarkers in evaluating vascular and inflammatory diseases like pyogenic granuloma.
