Introduction/Background Ovarian cancer is a gynecological tumor that causes the most deaths in developed countries. Early diagnosis is very important in terms of life expectancy. Both clear cell cancer and endometrioid type ovarian cancer from ovarian tumors are associated with endometriosis. Sometimes it is seen in combination with endometriosis, sometimes it can develop from the endometrioma capsule.

Methodology We had a 44-year-old 6-month-old married woman in the premenopausal period, gravid 0, followed for 6 months by thinking of a simple cyst, endometrioma growth of about 65 mm, ca125 : 225 iu, and ca19.9 high output of 11 455 iu, USG and MRI also showed the presence of 39 mm solid areas containing calcified areas on the cyst wall, minimal fluid appearance around the cyst

Abstract #43 Figure 1

Macroscopic view of the right USO-Ovary

Results After the suspected malignancy in the frozen examination, Unilateral salpingo oophorectomy,, Staging was performed. The uterus and other tuba ovaries were left. Final Pathology: Stage IA, gr 1, good differentiation, no capsule involvement, we performed fertility-sparing surgery. The patient was placed on post-op follow-up

Conclusion As a result, the patient was followed up with the diagnosis of endometrioma cyst. Unfortunately, during the follow-up, both the endometrioma and the papillary structure within the endometrioma were omitted.In particular, endometriod or clear ca cell ovarian cancer should be kept in mind in the premenopausal period, in ovarian masses containing large endometrioma and intra-cyst papillary structure.In those who do not have children, fertility-sparing surgery should be planned.
