Department of PathologyEndometriosis occurs in about 10-15 % of women in reproductive age and incidence of the disease is up to 50 % in patients which suffersfrom chronic pelvic
pain, dysmenorrhea and infertility. Although endometriosis is one of the most investigated disease of gynecology, itspathogenesis is still not clear completely. Tumor necrosis factor alpha (TNF-α) is the most effective proinflammatory cytokine producedin response to tissue injury and chronic inflammation. Interleukin 6 (IL-6) is another cytokine involved in the regulation of
inflammationreactiones and immune system, cell differentiation, cell proliferation, hemopoiesis and tumorigenesis. Inspite of the studies done so farshows that TNF-α and IL-6 presence in patient with endometriosis, there was no comparative immunohistochemical studys hows thepresence of these cytokines in normal and endometriotic tissue and the distribution in the cell types. In this study it
is aimed to investigateTNF-α and IL-6 expressions of normal and endometriotic tissues in the human by immunohistochemical methods. Tissue sections thatwere examined in this study obtained from tissue biopsies of ectopic endometriums taken from 24 women between the ages of
20-40.Additionally, the tissue sections taken from the normal endometrium obtained from 10 patients without any endometrial dysfunction dueto dilation or curettage are also evaluated as a control group. It was observed that TNF-α and IL-6 expressions are at varying levels fromweak to moderate in the control groups in surface and glandular epithelium. However there is no evidence of a significant staining of thestromal cells. It is found that TNF-α and IL-6 immunoreactivity is significantly increased in the epithelial cells, stromal cells and macrophageswhich are in endometriotic tissues when these immunoreactivity rates in control endometrium are compared. Expression of TNF-α and IL-6are both strong in ectopic endometrial tissues. This situation give rise to the tought of the two cytokines may have the same, parallel effectsduring the process of pathogenesis and development of the disease. When we evaluated the results together, we achieved the conclusionthat bothTNF-α and IL-6 are important cytokines that involved in the pathogenesis of the endometriosis.
