Distribution of estrogen and progesterone receptors in Epulis Fissuratum

Abstract

Statement of Problem: Epulides Fissurata (EF) are common proliferative and denture- induced lesions of the oral cavity with a predilection for female. This suggests a possible role for sex steroid hormones in the development and progression of these lesions. Purpose: The objective of this study was the immunohistochemical evaluation of epulis fissuratum of the oral cavity for estrogen and progesterone receptors expression in epithelial, stromal, inflammatory and endothelial cells populations. Materials and Methods: In this cross-sectional study, 15 samples of formalin- fixed, paraffin- embedded epulis fissuratums including marginal mucosal tissues in 4 cases as a control group, were immuno-histochemically evaluated for estrogen and progesterone receptors protein expression. Result: In 10 cases, estrogen receptor positivity was found within the epithelium and progesterone receptor immunoreactivity was present in 7 cases. Stromal cells exhibited estrogen and progesterone receptor immunostaining in many cases but only few cases showed expression of these receptors in the inflammatory and endothelial cells. Estrogen and progesterone receptors were also detected in some cases containing salivary glands tissue. Conclusion: Although chronic irritation may be the initiating factor for the occurence of epulis fissuratum, some of the cells in the lesion, could be potential targets for estrogen and progestrone hormones
