摘要: OBJECTIVE: To compare histologically and stereologically the endometriotic nodule of rectovaginal septum to peritoneal endometriosis. DESIGN: Morphometric investigation, cytokeratin vimentin content, steroid receptor evaluation were performed on tissue from peritoneum (n = 52) nodules 68). SETTING: An academic teaching hospital. PATIENTS: Biopsies taken 120 patients undergoing a laparoscopy for infertility and/ or pelvic pain (52 typical black implants 68 septum). None treated. RESULTS: Mitotic activity was found be significantly different in The suggested that stroma is not mandatory invasion glandular epithelium nodule, which is, like adenomyoma, circumscribed nodular aggregate smooth muscle elements. Cytokeratin content as well estrogen (ER) P (PR) lower both types lesion when compared with eutopic endometrium. But immunoreactivity epithelium, ER PR lesions. CONCLUSION: It disease endometriosis must called adenomyosis adenomyoma. Its histopathogenesis probably related implantation regurgitated endometrial cells but metaplasia Mullerian rests.
