In this study we aimed to investigate the expression of Fas protein by immunohistochemistry between ovarian endometriomas and endometriosis related ovarian tumors, endometrioid and clear cell carsinomas. Ovarian endometriosis (n = 22), ovarian endometrioid adenocarsinomas (n = 12) and ovarian clear cell carsinomas (n =8) histopathologic samples were included in this study. When we compared the epithelial Fas expression among three groups, we observed that endometriomas express significantly higher epithelial Fas than both ovarian tumors (P
