Endometriosis and possible malignant transformation.

By examining the cause of infertility for a the period of three years in the two largest hospitals in Belgrade, we found 453 cases of endometriosis out of 683 cases of laparoscopy. During the procedure, removal of endometrial foci, histological examination of the sample and removal of genital and peritoneum abnormalities by laser were carried out. Interestingly, in only 8% of the cases were cancerous changes of the ovary diagnosed. Out of 36 patients with established diagnoses, hysterectomy and bilateral salpingo-oophorectomy were performed in four cases.
