Moreover, the presence of hemorrhagic areas in the fibrous capsule of DC<\/jats:styled-content> could also contribute to the increase in osteolytic activity. The aim of this study was to compare immunohistochemical expression of nuclear factor \u03baappaB (RANK<\/jats:styled-content>), RANK<\/jats:styled-content> ligand (RANKL<\/jats:styled-content>), and osteoprotegerin (OPG<\/jats:styled-content>), vascular endothelial growth factor (VEGF<\/jats:styled-content>) and angiogenic index in RC<\/jats:styled-content> and DC<\/jats:styled-content>.<\/jats:p><\/jats:sec>Methods<\/jats:title>These proteins were evaluated in 20 RC<\/jats:styled-content> and DC<\/jats:styled-content> by immunohistochemistry.

The higher VEGF<\/jats:styled-content> expression in RC<\/jats:styled-content> might be related to nature of these lesions, where the inflammatory process contributes significantly to these
